分布式电源的快速发展给传统的电力系统注入了新的活力，同时也带来了新的挑战。本文在配电网几种常见的继电保护方案的基础上，结合分布式电源的特点，对分布式电源接入电网不同位置时对电网继电保护的影响进行了理论分析和仿真研究。研究表明，分布式电源接入配电网不同位置时，对电网继电保护动作将会产生不同程度影响，有时甚至会导致保护误动或拒动。

The rapid development of DG brings traditional power systems about both energy and new challenges. This paper is based on some usual proper protection scheme, combines the characteristics of DG as well, takes analysis on the influence of DG to the distributed power system at different location in theory and simulation. It indicates the DG at different location has different impact on the distributed power system. Sometimes, it may cause action null and void.
