✦ Synopsis
The propagation of HVDC converter station generated RF signals through a 345 k V AC switchyard to injection on the AC lines has been examined. A one-line analytical model of the AC buses, yard equipment and converter transformers has been formulated based upon measured RF impedances. The calculations were compared with relative measurements of RF line currents as different filter banks were switched in and out. The results indicate that the model will be a promising means of analysis and mitigation of unwanted RF effects.
Phase-to-phase coupling and extension of the approach to a three-line model have been considered but absolute RF measurements would be required prior to any definitive assessment.
