Abstract

This research project uses the existing capacitors, reactors and other reactive power resources in substations to construct the first regional reactive power and voltage emergency coordinated control system to solve the voltage problems after DC commutation failure or blocking. The system adopts the centralized control structure of master station, sub-station and executive station. The coordinated control master station communicates with AVC master station and converter substation sub-station to determine the fault, and then sends action instructions through the optical fiber communication to reasonably switch the capacitors and reactors of relevant substation, so as to give fast and effective reactive dynamic compensation to key nodes of the power grid to avoid voltage collapse.
