分布式发电技术在电力系统的应用对电力系统的操作和控制产生了很大的影响。其中很重要的一个方面就是它对配电网继电保护的影响，对传统配网保护带来了灵敏度降低甚至拒动、误动等继电保护问题。本文重点探讨了分布式发电对三段式电流保护的影响，并应用MATLAB软件进行仿真验证。

Distributed generation technology applied to power system has brought significant changes. And the impact of distributed generation on relay protection is an important aspect, this brought to the protection of traditional distribution network refusing action and error action, reduce problems such as sensitivity. In this paper, the influence of distributed generation are discussed mainly influences the three-step current protection, and use MATLAB software simulation. Finally, according to the simulation verifies the specific analysis..
