摘要：
Many intelligent devices for measuring and monitoring such as merging unit and intelligent terminals are located in the local control cabinet in the construction of the smart GIS substations. These devices inside are vulnerable to electromagnetic disturbance induced by disconnector switching operations. Mastering the characteristics of the port electromagnetic disturbance of these devices is important for the EMC evaluation and immunity measures. Consequently, we designed and proposed a simulated experiment platform. Using steep pulse as the source, we measured the following data : the voltages between GIS rod and shell at the beginning and terminal of the GIS pipe, the port voltage between GIS shell and ground, the port disturbance voltage on the simulated intelligent sensor side, and the port disturbance voltage on the simulated local cabinet side. The voltage waveforms were compared with IEC standard from time domain and frequency domain aspects and fully analyzed. It is validated that the voltages from this platform are representative of the port disturbance and are in accordance with IEC standard damping oscillation waveform. Also, they were compared with the disturbances of GIS substations. The results show that the characteristics of these waveforms are close to those of disturbances measured in GIS substations. Hence, this platform can produce disturbance voltages in line with the requirements of EMC immunity and protection technique of secondary equipment port. © 2017, High Voltage Engineering Editorial Department of CEPRI.
