Department of Power System Automation (OGM)

What is the Power System Automation Department?

The Power Systems Automation Department deals extensively with voltage regulation and reactive power management in the National Power System.

What does the Power Systems Automation Department do?

The Department's work is related to the development, design and implementation of automatic voltage and reactive power regulation systems in transmission substations, power plants and combined heat and power plants, as well as wind farms, photovoltaic farms and energy storage facilities. Automatic Transfer Station Control Systems (ARST) are autonomous multi-parameter control systems that regulate one of the selected voltage parameters and shape the reactive power distribution in an EHV or HV transformer station through automatic control of transformer tap changers. ARSTs can cooperate with power plant Automatic Voltage Regulation systems (ARNE), RES control systems (URST) and use available reactive power sources. At the same time, ARSTs are executing systems for the Department's superordinate System of Area Voltage Regulation (SORN), carrying out regulation in a selected area of the power system covering up to several dozen substations.
