摘要
直流融冰为500 kV及以上高压电网融冰的唯一方法。针对高压输电线路融冰装置SVC(静止无功补偿装置)的散热问题,通过对主流冷却方式、SVC运行环境的研究,研制了一套基于PLC、触摸屏、ModBus通信的密闭式纯水冷却自动控制系统,实现了对SVC冷却的远程、就地自动控制,同时系统引入抗干扰技术,克服了周边恶劣的电磁环境的影响。应用结果表明该控制系统性能稳定、运行可靠,有效地保证了直流融冰装置的正常运行。
DC based De-icing is the only way to melt ice for power grid 500 kV and above.In order to solve the cooling problem of de-icing device SVC,according to the research of mainstream cooling methods and system running environment,full-closed de-ion water-cooling system was designed.Based on PLC,touch screen and ModBus communication,the water-cooling system could be controlled locally and remotely.Anti-interference technology was also applied to the system to overcome the harsh electromagnetic environment.The running result indicates that the system is stable and reliable,ensuring the De-icing device running under the normal status.
