直流换流站交直流一体化电源系统实施方案探讨

Discussion on Implement Scheme for AC/DC Integrated Power Supply System of DC Convertor Station

目前,交直流一体化电源在常规交流变电站尤其在智能变电站中已逐渐成为主流配置方案,但其仍存在诸如接地隔离问题、直流变换电源(DC/DC)模块脱扣、蓄电池容量选择等问题。为此,分析和探讨一体化电源在交直换流站中应用的可能性、具体实施方案及注意事项。

AC/DC integrated power supply is gradually becoming the main trend configuration scheme in conventional sub-station especially in intelligent substation at present, but there are some existing problems such as grounding isolation, DC/ DC power supply module blurt and storage battery capacity selection. Therefore, this paper analyzes and discusses probabili-ty of application, specified implement scheme and matters need attention of integrated power supply in AC/DC convertor station.
