内容:
研究了一种基于电流源的多端口变换器,并将其应用于微网群的互联。针对微网群系统共模电压较高,易造成电机绝缘损坏、电磁干扰、通信故障、保护误动作等问题,提出一种改进的综合空间矢量调制策略。首先,对零矢量的冗余开关状态进行优选,抑制零矢量作用产生的共模电压尖峰。然后,研究变流器不同矢量排序方案对系统共模电压的影响,提出一种优选的排序策略,进一步降低无序的矢量排列造成的共模电压尖峰。最后,在MATLAB/Simulink环境下搭建含多端口电流源的微网群仿真模型,并针对所提综合调制策略进行仿真分析,结果证明了该调制策略的可行性和对共模电压抑制的有效性。A multi - port converter based on current source is studied and applied to the interconnection of micro - network. Aiming at the problem that the common mode voltage of microgrid system is high, which can cause damage to motor insulation, electromagnetic interference, communication fault and protection malfunction, an improved integrated space vector modulation strategy is proposed. First, the redundant vector state of the zero vector is optimized to suppress the common mode voltage spikes generated by the zero vector. Then, the influence of different vector sequencing schemes on the common mode voltage of the converter is studied, and a preferred sorting strategy is proposed to further reduce the common mode voltage spike caused by the disordered vector arrangement. Finally, a simulation model of microgrids with multi-port current source is set up in MATLAB / Simulink environment. Simulation results are presented for the proposed integrated modulation strategy. The results show that the feasibility of this modulation strategy and the effectiveness of common mode voltage suppression The
