摘要
针对目前配电网调匝式消弧线圈无法实时模拟,消弧线圈自动跟踪补偿与接地选线装置(简称消弧选线装置)只能进行开环测试,无法考虑装置在系统中实际运行情况,文中介绍了一种基于RTDS实时仿真系统的消弧线圈自动跟踪补偿与接地选线装置的试验研究方法。为验证消弧选线装置的实际工作情况,在RTDS中模拟了调匝式消弧线圈,建立了配电网经消弧线圈接地的仿真系统,并将被测装置所需要的模拟信号输出,装置的控制信号再返回RTDS中,从而形成消弧选线装置的闭环测试环境。按照试验要求进行了各项试验,对测试输出波形做了理论分析,从仿真结果可知,所介绍的方法用于消弧选线装置试验是切实可行的。
At present, the multi-tap arc-suppression coils in the distribution network can not be simulated in real-time field. The automatic arc suppression coil compensation and earth fault line selection device （refered to arc-suppression line selection device） can just be tested by open-loop method, resulting no information of its actual operation in the system in the test. So an experimental study method is introduced in the paper for the arc-suppression line selection device based on RTDS real-time simulation system. To verify the actural work of the arc-suppression line selection device, the multi-tap arc-suppression coil is simulated and the distribution network with arc-suppression coil grouding is built in RTDS. In the simulation system, the device under test receives the desired analog signal and return the control signal to the RTDS, forming a closed-loop-test environment for the arc-suppression line selection device. According to test requirements, various experiments and theoretical analysis of output waveforms are done. From the simulation results, the method described in the paper is practical and feasible.
