35kV配电网铁磁谐振过电压及抑制措施研究

Study on Ferroresonance Overvoltage in 35 kV Power Distribution Network & its Countermeasure

以榆林供电局府谷变电站为原型,基于ATP-EMTP程序平台,建立了该变电站35 kV系统的仿真模型并进行了相应的研究与分析,给出了各种抑制谐振措施的仿真计算结果,证明采取中性点接排线性电阻的方法能较好地抑制铁磁谐振。

Taking Fugu substation in Yulin Power Supply Bureau as an example, based on ATP-WMTP program platform, the simulation model of 35kV system is established, and corresponding research and analysis are conducted. The simulation results of different suppressing fen＇oresonance measures are given. It is proved that the operation mode with neutral point non-linear resistance can effectively suppress ferroresonance.
