overhead transmission lines which called «North-East-South transit»
It allowed to

increase the transit potential of the NES in the direction of North-South of Kazakhstan, to ensure coverage of the electricity needs of railways, energy-intensive facilities of the mining industry, and also to create conditions for the development of renewable energy sources, which is especially important in the concept of transition to a “green economy” that implemented in Kazakhstan, and also to strengthen the connection of the Eastern zone with the unified electric system of Kazakhstan.

to automatically prevent and localize emergency modes in the event

of regulatory disturbances , and it performed :

-in order to prevent disturbances in power system stability
- in order to eliminate asynchronous modes
- prevent unacceptable reduction or increase in frequency, voltage
-prevent unacceptable current loads on electrical equipment
-increase the allowable power flow in the network

the size of the decision table for cross-sectional flows, as

well as the magnitude of control actions, is automatically determined directly during the operation of the emergency control automation system. In this case, there are two options. According to the first - the calculation is carried out by specialists or coordinating complex, according to the second - directly at the object.
