摘　　要：针对蒙西电网内各发电厂实际投运的锅炉汽包水位保护逻辑功能不符合《防止电力生产重大事故的二十五项重点要求》的情况,对于无故障信号判断功能的汽包水位保护逻辑,提出优化与改进方案;列举了该方案在工程中的典型应用实例,并指出了应用过程中的注意事项及逻辑优化后的检查试验方法。With protection function of boiler water drum level actually operated in respect power plant in Western Inner Mongolia Power Grid,can not conform to 25 Key Requirements for Preventing Major Accident of Electric Power Production,aiming at water drum level protection logic with non failure signal verification function,put forward optimization and improvement program.Typical actual applied example for this program has been enumerated in project.Point out attention during application and verification testing method after logic optimization has been provided.
