基于测量阻抗变化的含IIDG配电网保护研究-Research on Protection of IIDG Distribution Network Based on Measurement of Impedance Change
URL description:
含IIDG配电网,由于电力电子器件的限流控制以及不同的控制策略,会导致传统保护失效。因此提出了一种通过采用故障前后线路两端测量阻抗幅值的差值变化和线路两端测量阻抗相角差变化为判据的含IIDG配电网保护方案,该方案可以实现配电网区内外故障的有效识别,实现保护的正确动作。方案的有效性通过PSCAD/EMTDC仿真软件进行了验证。;Including IIDG distribution network, due to the current limiting control of power electronic devices and different control strategies, traditional protection will be invalid. Therefore, an IIDG distribution network protection scheme based on the difference between the amplitude of the impedance measured at both ends of the line before and after t
