The work of thermal power plants has been fully restored, the Ministry of Energy reported.
The Commission created to study the emergency situation on January 5 on the power lines of the unified energy system of Central Asia determined the cause of the incident.
“According to the preliminary data, the protection system triggered an unscheduled shutdown of steam-gas installations at Talimarjan TPP. As a result, there was a surge in capacity on transit lines connecting the Unified Energy System of Central Asia with the Unified Energy System of Russia and Kazakhstan, which led to a disruption in the stability of the parallel operation of power systems,” the statement says.
Emergency control systems were activated on the power lines, as a result, the power systems of the Northern part of Kazakhstan were separated from the UES of Central Asia. The frequency of the UES CA dropped to 48.15 Hz. At the same time, a number of consumers were disconnected by automatic equipment and power units of thermal power plants (TPP) were unloaded.
It is noted that the triggered emergency response system prevented the possibility of larger-scale problems and devastating consequences for power units.
