Electrical power distribution for Oil & Gas applications

Greater challenges...Oil and gas companies must meet the challenges arising from greater demand for resources that are more difficult to access and extract. The heavy investments required must be returned faster. This requires state-of-the-art technology based on international know-how as well as extremely reliable and high-performance equipment.

...and consequent changes For electrical distribution systems in the oil and gas industry, this means far-reaching changes that call for new solutions.

Complex international projectsThe high investments lead to a joining of operational forces. Project organization becomes more complex with international partners providing a vast array of different competencies.Engineering firms, contractors and oil companies want a partner with solid experience in this field who can provide proactive support both locally and globally from the beginning to end of the project.

Know-how and experienceContinuity of service in electrical installations is vital to the profitability of heavy investments in oil and gas production. Experience in electrical engineering and technical know-how are essential to work out the optimum solution among the many alternatives.The electrical partner must have the means to carry out the necessary studies on system architecture and on the operating dependability and reliability of networks. It must also have in-depth knowledge of local and international standards given the ever increasing importance of safety and environmental considerations.

Enhanced performance and reliability of equipmentThe stringent specifications for installations mean that performance levels must be high. The equipment must be standardized, but offer all the features required to optimize costs and energy availability.The trends below are now commonly observed.b Increasing power levels, with more and more electrical motors, particularly for MV applications. Sites up to 100 MW are now common and others can reach 700 MWb Increasing voltage levels, with MV distribution now prevalent, where 3.3 kV is often replaced by 11 kVb High currents up to 4000 Ab High short-circuit currents, often 50 kA at 11 kVb Reductions in size and weight, made necessary by the constraints weighing on floating installations (offshore, FPSO, etc.) and the cost of shelters for onshore installationsb More intelligent switchboards to facilitate integration in electrical monitoring and control systems (EMCS)

Other electrical network studies

b Harmonics: control electrical pollution.

b Overvoltages and insulation coordination: guarantee equipment dielectric strength is respected according to expected overvoltage levels (permanent or temporary overvoltages or surges due to switching or lightning strikes).

b Dependability: guarantee the availability of electric power to increase the reliability of installations adapted to the application.

b Electromagnetic compatibility (EMC): design installations that are fully protected against electromagnetic disturbances.

Schneider Electric global service The work carried out for this project included: b Load flow and voltage profile studiesv Sizing of equipment (cables, lines, transformers) according to the installed powerv Calculation of voltage drops over the various linksv Positioning of power transformer tap changersb Short-circuit current calculationsv Maximum short-circuit current values (device sizing)v Minimum short-circuit current values (protection settings)b Protection studyv Choice of protection devicesv Determination of settings according to the various operating modesb Dynamic stability studyv Determination of maximum fault clearing times enabling motors reaccelerationv Impact of high power (7 MW) motor starting on voltage levelsv Impact of voltage drops due to the upstream network (220kV)v Design of a load shedding plan

Detail of design services Calculation of short-circuit currents These calculations are achieved using network modeling as defined in IEC 60909. They enable the maximum and minimum short-circuit currents (symmetric and asymmetric) to be determined for phase to phase and phase to ground faults. These calculations are essential for checking:b Making and breaking capacity of interrupting devicesb Electrodynamic withstand of equipment (switchboards, busbars, etc.)b Thermal withstand of grounding devicesb Site grounding characteristicsb Protection settings Protection studyThis study enables the type of protection to be determined (over current, directional, differential relays, etc.) by taking into consideration the various technical and economic criteria of the oil process. Protection settings are defined according to:b Short-circuit currents of the different operating modesb Transformer switching currentsb Motor starting or re-energizing currentsb etc.

Dynamic stability studyThe main objective of a network dynamic study for this type of installation is to estimate the behaviour of high power asynchronous motors should an electrical incident occur.For example, a phase to phase fault in the installation creates a voltage drop and the slowing of motors of substations close to the faulty feeder. If protection setting times are too long, the motors will slow too much to ensure that all loads can be fully brought up to speed once the fault has been cleared.Pre-determined load shedding will allow priority loads to be rescued. Furthermore, for this installation, the study enabled network behaviour to be checked should the automatic transfer system (ATS) installed in the main substation, operate.In the event of a fault on one of the 220kV/30kV transformers, the ATS ensures busbar changeover in less than 500ms. The simulation carried out enabled system stability and the re-energizing of high power motors to be validated.

Clustered oil and gas production field StakesTengiz is one of the most important O&G fields in Kazakhstan: 285,000 barrels a day of high quality production. The field reserves are estimated at between 6 and 9 billion barrels and production should reach 750,000 barrels in 2010, corresponding to an increase of 163% over 7 years.The project aimed to propose an Electrical Distribution solution for new sites intended to increase the existing gas production. In such a project, the availability of electrical power from the HV network connection point to the LV load is a main concern.
