摘　　要：随着电力电子装置在电力系统中的大量应用,电力系统电力电子化的趋势越来越明显。电力电子设备引起系统振荡的问题逐步显现,现已成为影响系统稳定运行的重要因素。对电力电子化电力系统出现的各种振荡问题进行了探讨,分析了系统振荡的发生机理。在此基础上,研究了电力电子化电力系统振荡的抑制方法,仿真与部分实际应用成果表明提出的解决方案可以有效地抑制振荡。为分析和抑制电力电子化电力系统的各类振荡提供了参考。With the extensive application of power electronic devices in power systems, there is a growing trend that the power systems have been power-electronized. Oscillation of power systems caused by power electronic devices is gradually emerging, and has become an important factor that affects the stability of power system. This paper discusses several types of oscillations in power-electronized power systems, and analyzes the mechanisms of these oscillations. On this ba- sis, mitigation scheme of these oscillations are investigated. Simulation and some practical application results prove the effectiveness of the proposed countermeasures. This paper could be a reference for analysis and mitigation of oscillations in power-electronized power system.
