| Abstract: | Based on the characteristics of distributed photovoltaic generation,the impact on relay protection in the system connected with distributed photovoltaic power station is analyzed.For the three typical 10 kV accessing modes such as dedicated line,T connection and distribution room connected to the distribution system in Xi′an area,the corresponding configuration of relay protection is proposed.Taking a 9.8 MW distributed photovoltaic power generation project in Xi′an for case study,a protection configuration scheme is proposed according to the configuration principle and the practicability and effectiveness of the proposed schemes are verified by the analysis of the protection setting. |
