摘要:
本文针对微电网故障问题,通过分析PQ和VF控制策略的逆变器运行特性,建立了基于逆变器控制策略的数学分析等值模型,提出了故障状态边界条件. 结合微电网孤岛运行时的工作特点,利用故障前后的节点电压和节点电流,推导出微电网处于孤岛运行状态并发生三相短路故障时,公共耦合节点(PCC)处的电压与电流求解方程,建立了较为精确的故障分析方法. 最后利用PSCAD建立了220 V低压微电网的仿真系统,验证了所述方法的正确性.
Abstract:
Aiming at the problem of micro-grid faults,this paper by analyzing the operating characteristics of the inverter controlled by PQ and VF develops an equivalent mathematical model based on the inverter control strategy,and gives the boundary condition of fault state. The work characteristics of the micro-grid island operation is considered by using the node voltage and node current before and after fault state,derived the equation of voltage and current at PCC(point of common coupling),and a more precise analysis method is established when the system is in three phase short circuit fault. At last,by using the PSCAD,a simulation system of isolated island operation of low voltage of 220 V is built,and the validity of the proposed method is tested.
