The Use of Special Tools for Emergency Control in the Russian Far East Power Grid

This paper focuses on simulation of special tools for emergency control in the Russian Far East power grid. The main purpose of the paper is the exploration of possible use of HVDC back-to-back converter stations for power system braking for diminution of necessary size of remote load shedding in receiving part of the transmission system. EUROSTAG software has been used to analyze the possible methods for reinforcing the power system emergency control. An unusual way to improve the SPS performance has been investigated. The results of simulation of the repeated dynamic braking coupled with unloading of hydro-turbine at the Zeya hydro power plant with the use of angle differences are discussed. As well, emergency control of HVDC back-to-back converter stations at the Russian-Chinese frontier is presented.
