摘要

光伏(PV)系统遇到的最大问题之一是在故障时提供故障电流。随着PV数量的增加，故障电流分布与没有PV的系统有很大的不同。故障电流的变化也会影响保护装置的运行。本文在PSCAD程序中设计并网太阳能系统，并对并网的短电流值进行了校核。在故障条件下，分析了光伏系统对电网的贡献。用电流对故障和正常情况进行了比较

Short Circuit Analysis in Grid Connected with High Penetration of PV Systems

One of the biggest problems encountered in Photovoltaic (PV) systems is to contribute to the fault current in case of failure. The fault current profile differs considerably from the system without the PV as the number of PV increases. Operation of the protection devices is also affected by this fault current change. In this paper, grid-connected solar energy system was designed in PSCAD program and the short current values given to the grid were examined. The contribution of the PV systems to the grid was examined for the fault condition. Both fault and normal cases were compared by the currents
