摘要
电网扰动模拟装置作为一种电压源型电网模拟设备,其输出电压精度指标及与被测系统的并网稳定性至关重要。输出电压精度由输出阻抗特性决定。通过变压器隔离的电网扰动模拟装置输出阻抗分析比较复杂。通过传递函数和变压器初次级漏感等效方法,分析了变压器隔离型电网扰动模拟装置的输出阻抗,并通过输出阻抗分析了电网扰动模拟装置和被测设备构成系统的稳定性条件,实验结果证明了理论分析的正确性。
Power system disturbance simulation device as a voltage source grid simulation equipment, the output voltage precision and gird stability is crucial.The precision of output voltage is determined by the output impedance characteristics.Analysis of the output impedance of the transformer isolated power system disturbance simulation device is complex.Through the transfer function and the sides of the transformer leakage inductance equivalent, This pa- per analyzes the output impedance of transformer isolated power grid disturbance simulation device, and analyzes the stability conditions of the system composed by power system disturbance simulation device and the measured system, the experimental results prove the correctness of the theoretical analysis.
