摘要:

输电线路覆冰灾害严重影响特高压直流输电系统的正常运行。介绍目前特高压直流输电工程所使用的线路防冰的运行方式。对换流器并联融冰运行方式的效果进行分析计算,提出了融冰运行方式下的控制保护策略,并通过基于实时数字仿真器(real time digital simulator,RTDS)高压直流输电系统仿真平台对融冰运行方式进行试验验证。在锦苏特高压直流输电工程系统调试阶段对换流器并联融冰运行方式进行了现场试验。仿真试验与现场试验的结果均证明换流器并联融冰运行方式可行、有效。

Abstract:

 

Icing disaster on transmission line has seriously affected the normal operation of UHV DC transmission system. This paper introduced the operational mode of anti-icing in UHV DC transmission system, analyzed the effect of de-icing mode of parallel converters, and proposed control and protection strategies for this operation mode. Then, the de-icing mode was tested on the simulation platform of UHV DC transmission system based on RTDS (real time digital simulator). The field test of de-icing mode of parallel converters was carried out during the commissioning stage of Jin-Su UHV DC transmission project. Both simulation test results and field test results prove that the deicing mode of parallel converters is feasible and effective.

Key words: UHV DC transmission, de-icing mode of parallel converters, real time digital simulator (RTDS) simulation, field test
