摘要
目前,中心城区新建220kV变电站越来越多采用电缆进线方案,相应引起充电功率增加,所以220kV变电站感性无功配置的问题应引起重视。通过对变电站出线电缆引起充电功率增加的分析,提出220kV变电站无功补偿装置配置容量的设计方法,并以实例加以验证。由于该地区尚无配置感性无功补偿装置的220kV变电站,该方法对地区变电站新建工程无功配置方案具有较好的借鉴意义。
More and more power cable technique are used in the central of city, caused the charging power increase accordingly ,220kV substation reactive power compensation problems can no longer be ignored. In this article, based on the methods for charging power calculation, a study on capacity designing of reactive power compensation device configured in 220kV substation is proposed and verified. Because no inductive reactive power compensation deviees are installed before in this region, this new method has a good reference in new grid project design programs.
