The Kazakhstan Electricity Grid Operating Company

The end of summer for workers of power electrical stations is the time to complete repairs. In November first cold and snow will test their readiness for the next winter season. Generally speaking they do everything in order to make our homes bright and warm.

Today we’ll visit the central substation of the Kazakhstan Electricity Grid Operating Company (KEGOS).

The system operator has three main functions : transfer (inter-regional and international transit), process control and balance of the electric power system.

The branch of inter-regional electricity networks KEGOC in Akmolinsk is one of the largest (the territory of Kazakhstan is divided between nine branches of IEN). This is 4,200 kilometers of high voltage air lines, among which there is a record holder for extra-high voltage (1150 kV).

All incoming, consumed, produced and passing electricity is clearly visible on the panel (a large block display) of the regional dispatch center. The purpose of controllers is to maintain the energy balance, or in other words, the quality of electricity.

The ideal frequency is that of 50 hertz. If consumption is greater than generation, then frequency decreases and it becomes necessary to compensate it. A schedule of energy supply is made beforehand. But it happens that enterprises give some figures in applications, but in reality those figures are bigger. In such cases power stations have to rise generation level or to limit perpetrators.

Each line has its own color of a voltage class. Blue is for 500 kV, green – 220 kV. De-energized parts, sent for repairs glow on the screen with the yellow color.

Controllers work  all day long, four people in two shifts. The job of a manager is the constant concentration. It is necessary to make a right decision in a short period of time, so workers always feel responsible for people and equipment that are in operational management.

Switchgear 220kV.

Previously, everything was in one hand. Today generators operate separately, power transmission and dispatching are in hands of the state, and deliver to consumers is made by regional companies.

Electricity arrives in Astana by transit lines with 220 and 500 kV from Ekibastuz and from its own source –  town heat stations. Transformers convert voltage to 220, then from 110 to 10 kV and only in such form electricity is fed into the town network.

    Another new pictures showing small but detailed new knowledge of other side of the world. I really like them.

    Very modern and well-designed electrical gear! No comparison with the usual image of brown, rusty poles. I wonder where they get technology from.
