摘要
针对含有光伏电源的配电网故障检修的问题,分析了光伏电站发电原理,研究了其并网过程中给配电网带来的影响。对基于低电压穿越特性的多个光伏电源短路模型的配电网故障,提出采用迭代修正的方法来对配网故障进行分析和求解。建立仿真实验对提出的方法进行验证,结果表明,该方法能够准备地对含分布式光伏电源的配电网故障特性进行分析。
In terms of the problem of troubleshooting in distribution network with photovoltaic power supply, the principle of photovoltaic power generation is analyzed, and the influence on the distribution network during the process of grid connection is studied. In the light of the distribution network faults of multiple PV short-circuit models based on low-voltage ride-through characteristics, an iterative correction method is proposed to analyze and solve the distribution network faults. The simulation experiment is carried out to verify the proposed method. The results show that this method can be used to analyze the fault characteristics of distribution network with distributed photovoltaic power supply.
