【Abstract】 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.更多还原
