摘要 应用屏蔽移动车、高频电压电流探头、电磁场天线、光纤传输和频谱分析仪等设备与技术 ,设计了安装FACTS设备的变电站中高频电磁干扰的测试系统并实现了传导干扰与辐射干扰的同步触发测量。 4个安装不同类型SVC的变电站的现场测试和分析表明 ,SVC的高频电磁辐射集中在 10kHz~ 3.5MHz,最大辐射强度为磁场 0 .87A/m和电场 114V/m。将测量数据与IEC6 10 0 0 4系列电磁兼容标准比较后 ,针对基于SVC的电磁辐射干扰提出了两项抗扰性试验的具体改进建议。 By applying shielded mobile vehicle, high frequency voltage and current probes, antennas, optical fiber transmission, spectrum analyzer and such other equipment and techniques as these, an measurement system is designed to measure the high frequency emissions in FACTS-based substations, which can achieve synchronous triggering and measurement of the conductive and the radiated interference. On-site measurements in four different SVC-based substations demonstrate that the high frequency electromagnetic emissions produced by the SVCs are mainly from 10 kHz to 3.5 MHz, with the maximum emission amplitudes 0.87 A/m and 114 V/m recorded for H- and E-field respectively. A correlation comparison is also made to the present EMC Standards IEC 61000-4 series, and two items of concrete recommendations of changes for immunity tests are presented specifically for SVC-based radiated emissions.
