摘要：
DC power control for AC systems after fault is one of the key problems for AC/DC transmission systems. Aiming at improving the recovery characteristics of frequency and AC voltage for an AC system after fault, we put forward an energy area compensation method of DC power. The method obtains DC power order and duration time accurately based on local measurements to regulate retardation area online. With this method, oscillation of AC system can be suppressed after AC faults at the rectifier side. Moreover, it can prevent continuous commutation failure by improving frequency and AC voltage recovery after faults at the inverter side. Meanwhile, using the proposed method, we made a simulation on an electromagnetic transient simulation model, and the results proved the effectiveness of the method. © 2016, High Voltage Engineering Editorial Department of CEPI.
