摘要
华东地区某特高压直流输电换流站由于冬季环境温度低,导致阀外冷反渗透系统产水流量大大减少,对该换流站冬季大负荷安全稳定运行造成隐患。经过现场勘察及问题分析,提出一种在外冷补水管路增加电加热器方案,以解决以上问题,也为其他换流站解决类似问题提供了一定的参考和借鉴。
Due to the low ambient temperature in winter,the water flow of the external cooling reverse osmosis system of an UHVDC converter station in East China was greatly reduced,which caused hidden dangers to the safe and stable operation of the converter station in winter with large loads.After on-site investigation and problem analysis,a scheme of adding electric heaters to the external cooling make-up pipeline is proposed to solve the above problems,and it also provides a certain reference for other converter stations to solve similar problems.
