Hello
What is this room for and what this people are doing

[Ophiolite]

It is the control room of a Thermal Power Station in India, most likely the one at Renukut in Uttar Pradesh. It looks like a posed photograph, but the operators would be monitoring the performance of the power station and controlling its output.

Hello
what is inside have you gone through it how control room work this station
 RE Generator
what is this

what is inside this thermal power station?

The main inputs are:
- a fuel supply (often coal from a nearby coal mine)
- a supply of air (from Earth's atmosphere)
- a supply of cooling water (from a nearby river or lake)

The main processes are:
- The air and fuel are burned in a furnace
- The heat boils water to produce steam
-The steam turns a turbine (and there is often enough energy left over to turn another turbine)
- The turbine turns a generator to produce electricity
- The steam is condensed into water in cooling towers.

The main outputs are:
- hot gases that come from the furnace are released out through a smokestack (or chimney)
- hot ashes from the furnace are put into a setting pond
-  electricity from the generator is carried through a switchyard and out to transmission towers

how does the control room work in this power station?

This pulls together many of the components of a power grid that you have been discussing:
- The major control is how much power the grid despatchers want to buy from this power station, and this controls all of the inputs, processes and outputs
- Many parts of the input, processing and outputs are monitored by Programmable Logic Controllers (PLC)
- The PLC sends measurements of inputs, processes and outputs (plus any warnings) to indicators on the wall, and computer terminals on the desk
- PLCs will be monitoring flow rates of fuel, air and water, temperatures in the furnace, and chemical composition in the smokestack.
- PLCs will be monitoring pressure, flow rates and temperature of water and steam in the boiler and turbines. They act as a governor on the turbine speed.
- PLCs will be monitoring current, voltage, power factor and temperature in the generators
- PLCs will be monitoring current, voltage, power factor and circuit breaker status in the switchyard and transmission lines. This is done through current and voltage transformers, feeding trivector meters.

This information is overlaid on a a diagram of the boiler and turbines, and a single-line diagram of the electrical switchyard.

Most of it is automatic (except the coal mining part) - the people are there mostly to detect and fix anything that looks wrong.
There are many other people involved in routine maintenance of other parts of the power station.
