±800 kV楚雄换流站是云广直流的输送端,云广直流线路由于电压高、输电功率大,孤岛方式下运行对全站供电安全可靠性带来巨大考验。通信电源作为电力通信系统的供电核心设备,为保证通信系统的稳定运行起着巨大作用,研究如何提高楚雄换流站通信电源的可靠性具有重要意义。文章主要从高频开关电源的组成及容量配置、蓄电池日常维护、高频开关检修管理等几个方面进行探讨,提出提高电力通信系统运行可靠性的方法。
± 800 kV Chuxiong Converter Station is the transmission end of Yun-Guang DC. Due to the high voltage and high transmission power, the Yun-Guang DC transmission line exerts a tremendous test on the safety and reliability of the power supply of the whole station. Communication power supply, as the power supply core equipment of power communication system, plays an important role in ensuring the stable operation of communication system. It is of great importance to study how to improve the reliability of communication power supply in Chuxiong converter station. The article mainly discusses the composition and capacity configuration of high-frequency switching power supply, battery routine maintenance, high-frequency switch maintenance management, and several other ways to improve the operational reliability of power communication system.
