NTPC BADARPUR PLANT DETAILS

• First Unit Commissioned 1973 (95MW)

• Installed Capacity 720 MW

• De-rated Capacity 705 MW

• Coal Source Jharia Coal Fields

• Water Source Agra Canal

• Unit Sizes 3X95 MW ,2X210MW

SOME IMPORTANT DATES FOR BTPS BTPS was conceived in 1965 to meet the

growing electricity demand of Northern Region.

The site construction activities started in 1968.

The plant became operational with the commissioning of its first unit on 26th July 1973, 2nd unit in ;74 , 3rd unit in ’75 , 4th unit in ’78 & 5th unit in ’81.

CONTROL AND INSTRUMENTATION LAB

AUTOMATIC CONTROL SYSTEMS

• Based on automating the equipments.• Safe operation under all plant disturbances

and component failures.• Requires 24 Volt DC, 4-20 m A to excite all

the controls.• System installed in BTPS is “OLD RUSSIAN

SYSTEMS”.• These are ACS which are slowly being

replaced by DCS .

ELECTRONIC CONTROLLERS• Electronic control unit (ECU) - Controls one or

more of the electrical systems or subsystems in a motor vehicle.

• At BTPS there were many electronic controllers employed by “BRITISH ELECTRICALS.”

• The panels there were of SCADA architecture but they still employed relays to automate the whole plant.

PID CONTROLLER

• Generic control loop feedback mechanism.• Calculates error values between SP and PV

values.• Minimises error values by adjustment of the

three parameters.• Absence of the integral term prevents system

from reaching target value.

PID Equation:

This is the basic equation of a PID controller:Where;• Kp: Proportional gain, a tuning parameter

• Ki: Integral gain, a tuning parameter

• Kd: Derivative gain, a tuning parameter

• e: Error = SP − PV• t: Time or instantaneous time (the present)

TUNING METHODS

Method Advantages Disadvantages

Manual Tuning No math required. Online method. Requires experienced personnel.

Ziegler–Nichols Proven Method. Online method.Process upset, some trial-and-error,

very aggressive tuning.

Software Tools

Consistent tuning. Online or offline method. May include valve and

sensor analysis. Allow simulation before downloading. Can support Non-Steady State (NSS) Tuning.

Some cost and training involved.

Cohen-Coon Good process models.Some math. Offline method. Only

good for first-order processes.

A PID Controller

The supervisory panel at BTPS

NEW TECHNOLOGIES • A programmable automation

controller (PAC) is a compact controller that combines the features and capabilities of a PC-based control system with that of a typical programmable logic controller (PLC). PACs are most often used in industrial settings for process control, data acquisition, remote equipment monitoring , machine vision, and motion control.

• A programmable logic controller (PLC) or programmable controller is a digital computer used for automation of electromechanical processes, such as control of machinery on factory assembly lines, amusement rides, or light fixtures.

• Unlike general-purpose computers, the PLC is designed for multiple inputs and output arrangements, extended temperature ranges, immunity to electrical noise, and resistance to vibration and impact. Programs to control machine operation are typically stored in battery-backed-up or non-volatile memory.

• SCADA (supervisory control and data acquisition) generally refers to industrial control systems (ICS): computer systems that monitor and control industrial, infrastructure, or facility-based processes, as described below:

• Industrial processes include those of manufacturing, production, power generation, fabrication, and refining, and may run in continuous, batch, repetitive, or discrete modes.

• Infrastructure processes may be public or private, and include water treatment and distribution, wastewater collection and treatment, oil and gas pipelines, electrical power transmission and distribution, wind farms, civil defence siren systems, and large communication systems.

• Facility processes occur both in public facilities and private ones, including buildings, airports, ships, and space stations. They monitor and control HVAC, access, and energy consumption.
