METHOD AND APPARATUS FOR CONTROLLING VOLTAGE SOURCE CONVERTER OF HVDC SYSTEM

摘要

PURPOSE: A voltage source converter control method and apparatus are provided to perform power outage movement in the power outage of an alternating current (AC) network by supplying electricity which is stored in an energy storing device to a station and the AC network. CONSTITUTION: A determining unit (510) determines the power outage state of a first station and a second station. A converter reference voltage generation unit (520) produces converter reference voltage. The converter reference voltage controls a voltage source converter (VSC) which is included in a station of the power outage state. A converter reference frequency and phase generating unit (530) produces a converter reference frequency and converter reference phase for a voltage source converter. A control pulse generating unit (540) supplies a control pulse to the station of the power outage state.
