Abstract :
Ultra-high voltage direct current (UHVDC) converter stations produce high levels of carrier frequency noise which can cause harmful interference to power-line carrier and open-wire carrier systems. The noise models of converter valves and converters arranged with two 12-pulse valve groups in series per pole are given. Calculation results of noise interference on dc pole line and electrode line for the Xiangjiaba - Shanghai UHVDC project (plusmn 800 kV 6400 MW) based the noise models are presented and discussed. The PLC filter configuration for the UHVDC project meets the requirements of interference limits calculated by the models.
