| Abstract: | Relay protection of distribution network has essential impact on power supply quality. This paper firstly introduces relay protection used for present distribution network and then analyzes fault characteristics of the distribution network and problems such as difficulty in route selection and positioning for small current grounding fault, high resistance fault protection and reclosing technology. Meanwhile, it summarizes study status quo of these problems. At last, it analyzes impact of distributed power source connecting with distribution network on protection and expects development trend of relay protection of distribution network in the future. |
