摘　　要：针对区域间互联新型电力系统中时延影响广域阻尼控制器性能问题,首先分析了区域间互联新型电力系统中的数据传输时延组成;然后针对随机时延,提出一种新型电力系统时延补偿方法,可对时延进行自适应补偿;最后利用4机2区系统验证所提方法的有效性。通过对系统施加短时故障,对比分析随机时延情况下,分别采用固定时延补偿和本文所提时延补偿方法系统的稳定性情况。试验结果表明,提出的时延补偿方法可有效减小时延造成的广域阻尼控制器性能下降,提高电力系统的稳定性。Time delay affects the performance of the wide-area damping power system. To resolve the problem, the data transmission delay composition is first analyzed in the new interregional power system. Then, a new power system delay compensation method for random delays is proposed, and the delays can be adaptively compensated. Finally, the validity of the proposed method is verified on a 4 machines 2 area system. By applying short-time fault to the system, the stability of the fixed delay compensation and the proposed delay compensation method are analyzed in a case of random time delay. The test results show that the proposed delay compensation method can effectively reduce the delay performance decline and improve the stability of the power system.
