一种直流闭锁故障后的安控切机措施量计算方法及系统
摘要：
本发明涉及一种直流闭锁故障后的安控切机措施量计算方法，包括：预先计算不同类型直流闭锁故障相应的安控切机措施量；当发生直流闭锁故障时，根据直流闭锁故障类型采用预先计算的安控切机措施量。本发明提出的一种直流闭锁故障后的安控切机措施量计算方法，计算了不同闭锁形式下对应的安控切机措施量，在实际发生闭锁故障后根据闭锁形式选取对应的安控切机措施量，在保证直流闭锁故障发生后系统能够稳定运行的前提下，降低安控切机措施量，提高电力系统运行经济性和稳定性。
摘要（英）：

The invention relates to a safety control generator tripping measure amount calculation method after direct current blocking fault. The calculation method comprises the steps of calculating corresponding safety control generator tripping measure amounts corresponding to different types of direct current blocking faults in advance; and when direct current blocking fault occurs, adopting the pre-calculated safety control generator tripping measure amount according to the type of the direct current blocking fault. By virtue of the safety control generator tripping measure amount calculation method after direct current blocking fault provided by the invention, the safety control generator tripping measure amounts corresponding to different blocking forms are calculated, and the corresponding safety control generator tripping measure amount can be selected after the blocking fault actually occurs according to the blocking form, so that the safety control generator tripping measure amount can be lowered while operational economic efficiency and stability of the power system can be improved under the premise of ensuring stable operation of the system after the direct current blocking fault occurs.
