摘要
Abstract
In conventional high voltage direct current (HVDC) power transmission system,frequency controller is configured on the rectifier side.The inverter frequency control can”t be realized when telecommunication is interrupted between stations due to no signals of its inverter to be sent to the rectifier.An inverter-side frequency control method is proposed,which is suit for a DC system startup strategy and an automatic switching strategy between constant current control and constant voltage control when the telecommunication status is instable.In the end,the practicability and reasonability of the proposed strategy are verified by the real time digital system (RTDS) simulation results.The strategy provide a good reference for inverter-side frequency control without telecommunication between stations.关键词
