Measurement of Radio Interference Emission Around +/−100 MVAR STATCOM Valve Building Near 400/220 kV Substation

Abstract

Flexible AC Transmission System (FACTS) devices are inevitable to improve the performance of power supply system having the interconnection with solar and wind forms. The firing of converter valves of these large power electronics devices emits radio interferences, which may disturb the operation of nearby other delicate electronics devices. CIGRE, CISPR and IEEE had given guidelines for limits, analytical calculation, measurements and attenuation. In the present work the experiences of measuring radio interference around the valve hall is elaborated for three different operating conditions, including while injecting reactive power into the grid from STATCOM unit.
