Multi-coordinate in Substations side voltage and reactive power control system optimization, including the MCR controllable reactor pressure side, the low-pressure side of the stationary reactive power compensation apparatus of the MSVC, and the low-voltage bus voltage and current transformers, in the low pressure side busbars and a low pressure side capacitor banks are arranged hanging virtual air gap controllable reactor, providing inductive reactive power compensation, and the capacitor bank arranged on the low pressure side, to achieve inductive capacitive reactive power is continuously adjustable, multi-coordinated reactive power substation side optimization of the integrated control using the stationary type MCR MCR controllable reactor and the low pressure side side reactive power compensation apparatus MSVC coordination optimization control. The present invention uses a virtual air gap controllable reactor capacity can be achieved controllably adjustable reactor.
