Abstract: The automatic voltage control system of South Hebei Power Grid is a three grade coordinated control system including region , province and area based on layering and zoning principles. The system gets control instructions from North China Power Grid and computes the voltage target values of power plant and substation according to the network loss minimized and the voltage qualified as a constraint, regulates the reactive power of the units and switches the capacitors and reactances of substation, and also sen…
