摘要:

电力电子装置在电力系统大量接入改变了电网故障特征,适用于同步机激励下电网的常规继电保护面临挑战。电力电子化电力系统故障暂态特征复杂、持续时间较短,限制了被动检测保护技术的应用和发展,利用电力电子设备的可控能力可以提高继电保护对故障的甄别能力。文中总结了控制与保护融合的探测式故障识别方法的关键技术,对能够实现主动探测的电力设备进行了分类,阐述了实现注入操作的可行性和注入探测信号的物理限制,最后探讨了探测式故障识别方法的应用场景,并给出了研究展望。

Abstract:

The integration of a large number of power electronic devices into power system has changed the fault characteristics of power grid, which challenges the adaptability of the conventional relay protection excited by synchronous machines. The complex fault transient characteristics and short duration in power electronic system limit the application and development of passive detection protection technologies. The controllable ability of power electronic devices can improve the ability of fault identification of relay protection. The key technology of detective fault identification method is proposed based on the coordination of control and protection. Different types of power equipment that can realize the active detection are classified. Then the feasibility of the injection operation and the physical limitation of the injected detective signal are described. Finally, the application scenarios of the detective fault identification methods are discussed and the research prospect is given.
