一种适用于HVDC工程的有源滤波器设计方法
An Active Power Filters Design Method for HVDC Engineering
摘要
Abstract
With the large-scale integration of new energy sources such as wind and photovoltaic,the Ningxia power grid is facing the problem of high electrified power grids,extensive use of power electronic equipment,and intermittent fluctuations in new energy sources such as wind and photovoltaic.The harmonic problems and reactive power balance will become increasingly prominent,and the safety risks of converter station operation will be high.The reasons for the frequent action of AC filter circuit breakers caused by tap changer and reactive power switching in the current Yinchuan East Converter Station are first analyzed.Optimization measures for the coordina-ted control of active filters and large-angle DC control strategies are proposed.Through the selection of active filter capacity,calculation of primary equipment parameters,and calculation verification,significant optimization of frequent action of circuit breakers and tap changers has been achieved,and the low-frequency harmonic filtering effect of the converter station is verified through simulation,laying the foundation for the subsequent harmonic suppression scheme of the third DC circuit.关键词
