摘要
针对光伏发电系统并网逆变器主要按照经验确定调节器参数的不足,详细分析了基于PI和准PR调节的三相光伏并网逆变器的控制参数设计,通过Simulink仿真平台验证了该方法的正确性,并由对比可知准PR调节器能够更有效地抑制谐波。
In view of shortcomings of existing papers that the regulator parameters are determined in grid connected converter in photovoltaic system according to experience, the design of control parameters of three - phase photovol- taic grid connected inverter based on PI and quasi - PR regulators was analyzed in detail. The correctness of the method was verified by Simulink simulation platform. In comparison, it is known that the quasi -PR regulator can restrain harmonics more effectively.
