摘要
本文以光伏电源通过10 kV馈线接入配电网为例,利用PSCAD软件进行仿真,研究光伏电源对馈线电流保护和继电保护所带来的影响,指出对馈线继电保护的影响程度与光伏电源容量大小和位置等相关。
With an example of photovoltaic power supply paralleled into distribution network by 10 kV feeder line and using PSCAD software emulation, the impact of the photovoltaic power on feeder line current protection is studied in the paper, The result shows that the influence degree of relay protection of feeder line is relative to capability and position of pbotovoltaic power supply.
