• 摘要: 针对光伏电源接入500 kV变电站站用电后对系统保护的影响进行了研究。首先，介绍500 kV变电站站用电的一般接线方式和光伏电源基本模型；然后，根据500 kV变电站工程特点以及光伏布置，分析了光伏电源的发电功率、光伏电源的接入方案。最后，基于实际500 kV变电站站用电参数，搭建了光伏电源接入站用电的Matlab仿真模型。通过在该仿真模型上进行了短路故障仿真计算，分析了光伏电源接入对站用电保护系统的影响，并提出了改进的措施。

   

  Abstract: Photovoltaic generation connected to 500 kV substation was studied in this paper. Firstly, the general wiring mode of 500 kV substation station power and the basic model of PV generation were introduced. According to the characteristics of 500 kV substation and the structure of the station, the layout of PV modules, power supply of PV generation and the scheme of PV connected to system are represented. Matlab simulation model of PV connected to 500 kV substation station power was established based on the actual parameters of 500 kV substation. Based on the Matlab simulation model, the short-circuit faults simulations were tested and calculated, the influences on station power protection of 500 kV substation were analyzed, and measures of station protection were also proposed.
