KEGOC implements advanced technologies for the safety of power grids

KEGOC is constantly introducing advanced technologies to ensure the reliability of power supply against the backdrop of a steady increase in electricity consumption in Kazakhstan.

Due to the wearout of power plants, the risks of potential accidents increase. To prevent such situations, in addition to the construction of new power lines and planned modernization of facilities, KEGOC ensures the reliability of power grids through the use of modern emergency control systems. The company is included in the list of the world's leading power grid companies in terms of technological equipment.

The company has implemented a centralized emergency control system (CECS). The system ensures real-time reliability of the national grid and minimizes consumer outages in the event of power outages.

An emergency control system based on synchrophasor measurements of electrical mode parameters (WACS) has also been introduced. The technology allows you to promptly collect information about the parameters of the electrical regime from facilities located at hundreds of kilometers from each other. The system processes all data and, in case of threats, prevents them at an early stage. The project provides monitoring of the entire power system of the country.

In addition, KEGOC automated frequency and capacity control (AFCC). The system maintains the balance of the power system without the participation of personnel by controlling the load of power plants connected to it. The technology ensures the quality of electricity and the reliability of power plants in Kazakhstan. At present, Bukhtarminskaya HPP, Shulbinskaya HPP, Ust-Kamenogorsk HPP, Moinakskaya HPP, Ekibastuzskaya GRES-1 are connected to the system. In the near future, Aksuskaya GRES (JSC EEK) will be connected, in the future, GRES Topar (Karaganda GRES-2) will be connected.

The implemented technologies have repeatedly demonstrated their high efficiency. Thanks to advanced systems, KEGOC prevented a serious accident in the west of Kazakhstan due to a shutdown of a power unit at a thermal power plant of MAEK-Kazatomprom LLP, which led to an overload of the 220 kV transit Uralsk - Atyrau - Mangistau.

As a system operator of the electric power system of Kazakhstan, KEGOC will continue systematic work on the introduction of advanced systems to ensure the reliability of power supply to consumers.
