Abstract: |
With the deepening of China's electric power market reformation, reducing the power grid loss has become very important to power supply companies after separation. In order to improve the grid security and stability, further enhance the power grid voltage quality and reduce the loss, the optimized reactive voltage control of closed loop from the whole network has been an urgent necessity. Simultaneously, the integration mode are being extended gradually in regional power grid, the operation automation of power grid has been greatly elevated in recent years, the automatic distribution system SCADA / EMS has also been pervaded, and the "four remotes" of SCADA are more and more perfect. Therefore, on basis of SCADA / EMS system, the automatic voltage control system (AVC) optimizing the reactive power grid within the whole country is very necessary, which has provided an advanced control mean for accommodating the reactive voltage control under integration mode and realizing the safe, high-quality and economic run of modern power grid.
