Abstract Nowadays the automatic control device for voltage and reactive power is mainly implemented in 110kV or lower voltage level substations, which aims at controlling the voltage of low-voltage side and the power factor of high-voltage side. For 220kV substations with three voltage ranks, this paper offers a new approach of voltage and var integrated control based on MCR and MSVC. Considering the interaction between each side of the transformer, this method focuses on the bus voltage of three different voltage levels and the power factor of high-voltage side. Simulation model consisting of two main transformers with MCR at medium-voltage side and MSVC at low-voltage side based on Matlab/Simulink is established. And this simulation is compared with simulation of only installs MSVC in the low voltage side and only installs MCR in medium voltage side. Simulation results indicate the effectiveness in achieving qualified voltage at each side and general reactive power balance under different operating modes of the method of coordinately controlling medium and low voltage side.

Key words： Magnetically controlled reactor(MCR) reactive power compensation voltage/Var integrated control coordinative compensation power quality.
