摘要

暂态稳定分析在提供电力系统性能约束方面起着重要作用。分布式发电的渗透导致过流继电器整定的性能限制。本文研究了实际配电网过流保护继电器整定中有dg侵穿的暂态稳定性分析。为此，考虑电力系统不同地点的故障，对DG发电机的暂态稳定性进行了研究。然后，在继电协调保护中考虑了DG发电机的约束条件。案例研究基于一个实际的配电网，该配电网由两台容量为4mw的发电机组成，并在DIgSILENT软件中进行了仿真。

Protection Coordination constraints of Distributed Generation in Transient Stability

Transient stability analysis plays an important role in providing performance constraints in power systems. The penetration of distributed generation leads to performance constraints on the overcurrent relay setting.This paper investigates the transient stability analysis of real distribution network with DGs penetration for the protection overcurrent relay setting.For this purpose, the transient stability of DG generators is studied by taking into account faults in different places of the power system. Then, the constraints of DG generators are considered in relay coordination protection.The case study is based on a real distribution network that consists of two generators with 4 MW capacity, and the simulation is performed in DIgSILENT software.
