1.0 Introduction

1.1 Function

The function of the GE Frame 7-FA Gas Turbine Lube Oil System is to supply lubricating oil for the gas turbine and generator bearings, seal oil to the generator, trip oil, and oil to the suction side of the hydraulic control oil/lift pumps.

A blowout panel is normally located on the oil tank. This blowout panel is designed to relieve energy should there be an explosion within the tank.

1.3 AC Oil Pumps

The basic purpose of the turbine lube oil system is to provide lubricating oil to the turbine and generator bearings. Additionally, oil is provided to the hydrogen seal oil system and hydraulic controls fluid. Both AC Oil Pumps are in operation when the turbine is running below rated speed, such as during startups and shutdowns. Once the turbine reaches 95 % of rated speed, one AC Oil Pump will be shutdown, this pump becomes the “lag” pump. The running pump is the “lead” pump and it will meet the system oil supply needs.

With the unit on turning gear, only one AC Oil Pump supplies the needs of the oil system including “lift” oil.

1.4 DC Emergency Oil Pump

The DC Emergency Oil Pump acts as a backup for the AC oil pumps, and provides lube oil to the system in case of a loss of AC power. Like the AC pumps, it takes suction directly from the oil tank and discharges to the lube oil supply header but bypasses the coolers and filters.

1.5 Seal Oil Pump

The Seal Oil Pump and its associated AC/DC motors, supply oil to the hydrogen seal oil system in the event of failure of the lube oil pumps and/or loss of AC power (in the case of the DC motor). Like the lube oil pumps, the seal oil pump takes suction directly from the lube oil tank.

2.0 Lube Oil Tank / Reservoir

2.1 Oil Tank

The Lube Oil Tank/Reservoir stores all of the oil required by the Lube Oil System including the Seal Oil and Hydraulic Oil Systems. The oil holding capacity of the tank is 6,200 gallons. The tank is the foundation for the oil skid compartment and serves as the mounting base for the remainder of the lube oil system components. The tank and system components are housed below the turbine-generator centerline to allow adequate drainage from the turbine-generator bearings by gravity. All drain piping is properly pitched downward to assure positive drainage.

The lube oil tank itself extends down below the skid housing . The tank is rectangular in shape and is constructed of weld fabricated carbon steel. The interior of the tank is coated with an oil resistant protective coating. The tank is provided with miscellaneous connections for filling and draining. Blowout panels are located along the horizontal wall of the oil tank.

2.2 Lube Oil Tank Heater (23QT)

During standby periods, immersion heaters are used to maintain the oil at a viscosity as needed for turbine start-up. This is accomplished by three (3) immersion heaters (23QT-1, -2 and 3) installed in the oil reservoir. Temperature switch 26QL-1 is mounted on the side of the tank and controls the heaters to maintain fluid temperature. This switch brings the heaters into service with a decreasing oil temperature at 70ºF (± 2ºF). Temperature switch 26QL-1 will drop the heaters out of service on an increasingtemperature of 79ºF (± 3ºF).

If the heaters fail to function and the oil reservoir temperature drops below the point where oil viscosity exceeds 800 SUS, temperature switch 26QN-1 (located inside the tank) will initiate a low oil temperature alarm at a decreasing temperature of 56ºF (± 2ºF). 26QN-1, if indicating an oil temperature below 56°F (± 2°F), will prevent a turbine startup. [Saybolt Universal Seconds (or SUS) is used to measure

viscosity. The efflux time is Saybolt Universal Seconds (SUS) required for 60 milliliters of a petroleum product to flow through the calibrated orifice of a Saybolt

Universal viscometer, under carefully controlled temperature and as prescribed by test method ASTM D 88]

2.3 Lube Oil Tank Level (71QH/QL)

Normal operating oil level in the oil tank is 19.5” below the top surface of the oil tank. A level alarm device (float operated) is mounted onthe lube reservoir and operates two (2) level switches 71QH-1 (High Level) and 71QL-1 (Low Level)]. The switches are connected into the alarm circuit of the turbine control panel to initiate an alarm if the liquid level changes 3" (± ¼ “) above or below normal. The oil level is also visually indicated by a sight gauge on the side of the tank. Oil drain and fill connections are located on the side of the tank to facilitate those activities.

2.4 Mist Eliminator

The lube oil reservoir is equipped with a mist eliminator through which the vapor extractor takes suction on the air space above the oil level in the reservoir. The mist eliminator is comprised of a cylindrical fabrication filled with a substance similar to steel wool of the stainless steel variety.

Situated on top of the lube oil reservoir, the function of the mist eliminator is to do just as its name implies, remove any oil mist that might be entrained in the air and/or other gasses being drawn out of the reservoir by the vapor extractor(s) prior to the discharge of the vapors (gasses) to the atmosphere outside the lube oil accessory compartment. The misted oil is entrapped by the mist eliminator fill and returned to the reservoir by natural gravity flow.

2.5 Vapor Extractor

The vapor extractors are small centrifugal fans (23QV-2A and -2B) that draw air from inside the lube oil tank and return piping, and exhaust the air to atmosphere. This is necessary to remove any hydrogen that might collect inthe bearing pedestals or the oil tank, and to remove moisture-laden air inside the tank. The vapor extractors are driven by small, AC motors (88VA-1A and -B). Flow-regulating valves (FB1-1 and -2) on the exhauster discharges are set to maintain about 6” to 8” H2O vacuum inside the oil tank (with the turbine operating at base load).

Pressure switch (63QV-1) provides a low differential pressure alarm signal when there isinsufficient vacuum in the lube oil reservoir. This alarm occurs at 4.0 in H20 vacuum (±0.1 in. H2O vacuum) increasing, and clears at 3.6 in. H20 vacuum (±0.1 in. H2O vacuum) decreasing.

2.6 Vapor Extractor Controls

The turbine oil vapor extractor is manually controlled by a two (2) selection positions on the turbine controls screen.

The vapor extractors are set up to run in a lead/lag configuration and are designed to run one at a time. The selection of lead and lag extractor is made by the operator from the turbine control “motor” screen prior to startup. The lag extractor takes over whenever the lead extractor has failed to run, has been overloaded or if there is insufficient vacuum in the lube oil reservoir.

If the lag extractor is started automatically by the control systemdue to insufficient tank vacuum level, the lead extractor will be automatically shut off. Pressureswitch (63QV-1) provides a low differential pressure alarm signal when there is insufficient vacuum in the lube oil reservoir.

3.0 Lube Oil Supply

3.1 AC Lube Oil Pumps

The lube oil system is equipped with two (2) lube oil pumps (PQ1-1 and PQ1-2) to provide the lubrication and hydraulic oil needs of the gas turbine-generator. Each pump is capable of delivering 883-gpm of oil at a rated pressure of 110-psig. Under “normal” turbine operating conditions only one pump is required to supply all of the units oil needs. Both pumps are required during startup and shutdown.

A ball-check valve ties the two pump discharge lines to a common header, OL-4. Pressure indicators indicate pump discharge pressure: • PI-QA-1 for pump 1 (PQ1-1) and • PI-QA-2 for pump 2 (PQ1-2)The header takes the oil through coolers, filters, and to the various system functions.

The pumps are driven by vertically mounted AC motors (88QA-1 and 88QA-2). Additionally, the motors are equipped with motor heaters(23QA-1 and 23QA-2) to prevent condensation from forming in the motors when they are not in service.

3.2 Lube Oil Cooler 3.2.1 Capacity

There are two (2) 100% capacity “plate” type heat exchangers arranged in parallel to remove heat from the lube oil (OL-4 from the AC pump discharge supply) before it enters the lube oil filter and on to the bearing oil supply header. The heat exchangers are labeled LOHX-1 and LOHX-2. Under normal operating conditions only one (1) heat exchanger is required to adequately cool the lube oil.

The coolers are equipped with a transfer valve to allow operations to transfer oil flow from one cooler to another. Before doing so, however, the shown normally closed (NC) fill valve is “opened” to fill the standby cooler with oil prior to transfer.

3.2.3 Lube Oil Cooler Construction

Cooling water is directed through one cooler at a time by aligning butterfly valves located in the cooling water lines like the one shown in here. The heat exchangers are of the counter flow type meaning the oil and cooling medium travel through the exchanger in opposite directions to one another as depicted in the cutaway drawing.

The purpose of the counter flow type exchanger is to keep from shocking the elements of the heat exchanger (in this case plates) with cold water against warm oil. As depicted, the cold water enters the heat exchanger in the vicinity of the cooled oil outlet and the warmed water exits the heat exchanger in the vicinity of the warm oil inlet. Cold to cold and hot to hot.

3.3 Lube Oil Filters

3.3.1 LF3-1

Upon leaving the lube oil cooler, the oil is directed through the appropriate piping to the lube oil filter(s). Each lube oil cooler is coupled with a specific lube oil filter, one such combination is seen here. The oil cooler LOHX-1 is connectedto the lube oil filter LF3-1. The other oil cooler / filter combination is connected at the discharge of the shown ball-check valves. Therefore, changing from one filter to the other for cleaning (changing filter elements) also changes the cooler in use.

Controls on the shown lube oil filter consist of a pressure differential gauge (QQ-21) and pressure switch (63QQ-21) that monitor the differential across filter LF3-1. The pressure switch alarms at 15 psid (±1 psid) pressure differential to indicate the need to switch filters and change out the filter elements in the dirty filter housing. The alarm clears at 11 psid (±1 psid) decreasingpressure differential.

3.4 Hydraulic and Trip Oil Supply

Turbine lube oil, downstream from the operating cooler / filter combination, provides suction oil to the turbine hydraulic system. This connection is shown here via the OR-1 header. The hydraulic system is a subject in its own and is covered in the “Turbine Hydraulic System Power-Doc.”

Further downstream, past a 4-in. orifice there is a 2nd connection, OLT-1, to the turbine trip oil. This system is also a subject in its own and is covered in the “Turbine Trip Oil Power-Doc.”

3.5 Bearing Oil Pressure 3.5.1 Regulation

Lube oil from the cooler / filter combination is supplied to a header labeled as OL.

Oil flow is then through an orifice flange to the Lube Oil Pressure Regulator (VPR2-1). Lube oil pressure is regulated by the Fisher diaphragm type pressure regulator. The valve is operated by fluid pressure, taken from a point downstream of the valve by way of a sensing line, and throttles oil flow to maintain pressure in the bearing header labeled OR. Should the regulator fail closed, the Oil Supply Orifice (FO-3) will maintain a minimum flow. VPR2-1 is calibrated for a bearing header pressure of 30 psig (± 5 psig).

3.5.2 Bearing Oil Pressure Monitoring

Oil pressure and temperatures are monitored by the turbine control system through the following devices that are located “downstream” of the minimum flow orifice and/or the pressure regulator. Regarding the temperature trip, to trip the unit, 2-out-of-3 logic is used, including both the alarm and trip temperature switches.

Thermocouples, LT-TH-1A and LT-TH-1B monitor the lube oil temperature.

Temperature Gauge QA-1 provides local temperature readings on an analog type temperature gauge.

Temperature Switch(s), 26QT-1A and 26QT-1B are the lube oil header high temperature “TRIP” devices, set at 175 ºF.

Pressure Indicator, QA-1A provides local lube oil header pressure indication.

Temperature Switch, 26QA-1 provides a Lube oil header high temperature “ALARM”,set at 165 ºF.

3.5.3 Bearing Oil Piping

The bearing supply header piping distributes cooled lube oil to the various components served by the Lube Oil System. Oil to the turbine is directed through the return header piping. This arrangement minimizes oil leakage (and thus the fire hazard), which could develop in the event of a supply header rupture. The return header gravity drains back to the oil tank/reservoir. Oil to the generator bearings and hydrogen seals does not pass through oil guard piping.

3.5.7 Generator #2 Bearing

The bearing header, OR, provides lubricating oil to the generator bearings. The #2 Generator Bearing is the journal bearing furthest from the pressure regulating valve. For this reason, significant pressure sensing devices are located at this feed line. There are two pressure switches (63QT-2A and 63QT-2B) as well as two pressure indicators (QT-2A andQT-2B) in this feed line, monitoring bearing oil pressure atthe point furthest from the supply. The pressure switch contacts close on a decreasing pressure at 8 psig (±1 psig) and re-open at 10 psig (±1 psig) increasing.

These two pressure switches function in 2-out-of-3 logic with an alarm pressure switch (not shown) to tripthe turbine.

The drain from the #2 Generator Bearing passes through a flow gauge (FG) to the Bearing Drain Enlargement. Thermocouples, LT-G2D-A and LT-G2D-B, provide feedback as to the Lube System Temp – Generator #2 Bearing Drain. The B thermocouple is a spare.

4.0 Emergency Pumps

4.1 DC Emergency Bearing Oil Pump

There is one (1) DC Emergency Bearing Oil Pump labeled as PQ2-1 that is powered by one DC Motor labeled 88QE-1. The purpose is to supply oil to the lube oil supply header in the case of a unit trip due to a loss of AC power. During a unit “startup” the DC oil pump will start as a test to ensure its functionality.

The DC pump discharge bypasses the unit heat exchangers and filters (in case this system is the reason oil pressure has been lost). Under these emergency circumstances the DC Emergency Bearing Oil Pump is used only to supply oil to the unit bearings during a “trip” coast down. Pressure switch 63QE-1 indicates the pump in service. A pressure indicator, QE-1, provides feedback as well.

4.2 DC Oil Pump Controls

The Emergency DC Oil Pump is controlled by the turbine control system and will start automatically if there is a unit trip due to loss of lube oil pressure (63QT). The Emergency DC Oil Pump will continue to run while coasting down.

The DC oil pump will also auto start with a signal from 63ST-1A or 63ST-1B on a Low Seal Oil Pressure Trip set at 3.5 psid (± 0.2 psid) (see Power-Doc on Seal Oil).

Pressure switch 63QE-1 gives indication that the Emergency DC oil pump is running or stopped and will display the status of the pump as “Running” or “Stopped” on the turbine controls screen.

After the unit comes to a stop on a turbine trip due to loss of AC power, the DC pump should only operate a few minutes per hour, in order to remove heat, while at thesame time conserving battery life. The DC pump should be run continuously if the bearing metal temperatures are above 250°F. The emergency pump is sized to clear the trip pressure switches 63QT-2A and 63QT-2B, but will not clear the alarm pressure level switches 63QA-1A and 63QA-1B.

4.3 Auxiliary Seal Oil Pump

Generator seal oil pressure is normally provided from the AC Lube Oil Pumps, coolers, and filter assemblies. The oil supply is from OL-11 through the ball-check valve, to OS (the seal oil supply).

The unit is equipped with an auxiliary seal oil pump for use when neither of the AC lube oil pumpsis available for service such as the case might be during an AC lube oil pump equipment outage with the gas turbine off line.

The seal oil pump can be powered by either its AC or DC motor that are arranged in a piggy back fashion. The AC motor (88QS-1) is used when AC power is available and the gas turbine is not running. The DC motor (88ES-1) is used when AC power is NOT available and is for Emergency situations only.

When the seal oil pump is running its discharge bypasses the systems heat exchanger and oil filters. For this reason the Seal Oil Pump is only run when necessary, meaning that the AC lube oil pumps are not available for some reason.

Pressure indicator OS-1 provides localindication that the pump is in service.

4.4 Auxiliary Seal Oil Pump Controls

The AC auxiliary seal oil pump motor will auto start on a signal from Pressure Differential Trip Switch 63ST-1A or 63ST-1B on a decreasing pressure differential of 3.5 psid (± 0.2 psid). These controls originate in the generator seal oil.

The DC auxiliary seal oil pump motor will auto start from the same switches, providing the AC oil pump does not start (due to loss of AC power). The seal oil system is also equipped with a low differential pressure Alarm switch, 63SA-1.

The AC and DC auxiliary sealoil pump motors have NO way of being started from the unit turbine controls display screen. The screen gives indication if the motors are Running or Stopped only. As shownon the turbine controls screen both the AC and DC auxiliary seal oil pump motors are “Stopped.”

5.2 Startup

Both AC Oil Pumps are in operation when the turbine is running below rated speed, such as during startups and shutdowns to supply oil to the system. Once the turbine reaches 95 percent of rated speed, the “lag” pump will shut down and the lead pump will carry the systems oil supply needs.

One vapor extractor is also in service during this time to remove any hydrogen gas and oil mist that might be in the oil tank in the airspace between the oil level and the top of the tank. Additionally, one lube oil cooler and its associated oil filter are in service.

On a unit startup signal from the turbine controls, the Emergency DC lube oil pump and Emergency DC seal oil pump motors will be automatically started to confirm availability,if needed.

Prior to startup the control room operator selects the lead and lag pumps, vapor extractors and lines up the desired remaining equipment.

The need for immersion heatersdepends upon the local conditions.

5.3 Normal Operation

During normal operations the running unit is monitored from the turbine controls screen by the “on-shift” control operator. The lead-pump remains the lead equipment until the system pressure control switches “AUTO” start the lag equipment or, the control operator makesa manual change in the lead, lag configuration using the appropriate turbine controls screen. This change in lead, lag configuration is typically accomplished during the weekly auto-start test of the lag-pump. Once the lag-pump has successfully started and been verified, then what was the lead-pump is shut down, placed in auto, and becomes the lag-pump.

6.5 Alarm Drop 75 - LUBE OIL PRESSURE LOW Logic Name is L63QAL_ALM

The implication is that one of the AC Lube Oil Pumps have shutdown. The cause of this shutdown should be investigated immediately. In the interim, it may be prudent to verify the availability of DC power to the DC Lube Oil Pump.

The signal originates from one (or both) of two pressure switch signals which monitor AC Lube Oil Pump discharge pressure (meaning the pressure will be higher than bearing oil pressure). These “auto-start” pressure switches (63QA-1A or 63QA-1B) are located in the AC lube oil pump header. The turbine speed signal is an inhibitor, as the speed must be greater than zero, for the alarm to be enabled.

6.6 Alarm Drop 76 - LUBE OIL PRESSURE SWITCH TROUBLE Logic Name is L63QT_SENSR

One of the pressure switches indicates a loss of pressure when, given the current operating condition, this is not possible. The faulty pressure switch should be investigated.

Pressure switches, 63QA-1B and 63QA-1A, monitor pump discharge header pressure. If one pressure switch should indicate lack of pressure, while the other one is normal, this would indicate probable pressure switch failure. The alarm comes in with a 10-second time delay. A parallel path for this alarm occurs if the motor contactor is closed (L52QA), the machine is otherwise normal (L1Z) and the pressure switches indicate no AC Lube Oil Pump is running.

The implication is there a high level in the oil tank. The level indicator at the oil tank will provide immediate verification. Causes might include an excess of clean oil returned to the tank or a cooler leak. If during system shutdown, it may be just the volumeof oil returning from the oil header and drain piping. The situation should be investigated immediately.

The signal originates from a level switch, 71QH-1, mounted on the oil tank. This device alarms on a high level of 3-inches above normal. The device logic name is L71QH.

The implication is there a low level in the oil tank. The level indicator at the oil tank will provide immediate verification. The situation should be investigated immediately as there is risk of loss of suction to the lube oil pumps. Probable cause is an oil leak at the tank or in the header at some other location. Look at various pressure gauges and potential alarms for an indication of where the oil might be leaking, if in the header. Another possible cause is that too much oil has been purposely drained.

The signal originates from a level switch, 71QL-1, mounted on the oil tank. This device alarms on a low level of 3-inches below normal. The device logic name is L71QL.

6.10 Alarm Drop 80 - LUBE OIL HEADER TEMPERATURE HIGH Logic Name is L26QA_ALM

High oil temperature as the turbine is rotating implies a lack of cooling. Probable cause is lack of cooling water to the coolers or failure of the temperature controller. Investigate the integrity of the oil coolers.

The signal originates from a temperature switch, 26QA-1, located in the lube oil header, downstream from the pressure regulator and still in the oil tank. The switch contacts close when the oil temperature raises above 165°F. As a permissive, the turbine speed must be above minimum firing speed (L14HM) to arm the alarm signal.

The implication is the turbine is in service and the coolers have apparently failed. Probable cause is the source of water.

A turbine trip occurs via a “2-out-of-3” logic string involving three temperature indicators as seen here. One permissive is that the turbine is running (above minimum firing speed – L14HM). The two trip temperature indicators are 26QT-1A and 26QT-1B, then there is the alarm temperature indicator, 26QA-1, that is used within the “2-out-of-3” logic.
