汽包水位保护逻辑是热工保护中最重要的一项保护,各发电厂的汽包水位高低保护都应符合《防止电力生产重大事故的二十五项重点要求》,对汽包水位保护在判断有无故障、坏点信号的功能上,北京京能热电股份有限公司再次改进及优化了汽包水位保护逻辑方案,增加水位信号偏差大转换保护。 Drum water level protection logic is one of the most important protection in thermal protection. The protection of drum level of all power plants should be in accordance with the “25 key requirements for preventing major accidents in electric power production” To judge whether there is any fault or dead pixel signal, Beijing Jingneng Thermoelectricity Co., Ltd. once again improved and optimized the logic scheme of the drum water level protection and increased the protection of water level signal deviation.
