摘　　要：通过统计集水井的有关数据,并利用公式计算出水位变化率,分析水位变化率的变化规律,设置合理的报警值,将水位变化率应用于水电站渗漏集水井现地控制系统后,当水泵异常或集水井来水量异常时,计算机控制系统报警表能够更加及时、准确、有效地报出水位变化的相关报警信息,及时提醒运行人员做好事故分析和处理,争取了远方和现场处理事故时间,及时发现设备异常,避免水淹设备事故的发生。By collecting relevant data from the water collection well and using formulas to calculate the water level change rate,analyze the change pattern of the water level change rate,and set reasonable alarm values.After applying the water level change rate to the on-site control system of the leakage collection well in the hydropower station,the computer control system alarm table can more timely,accurately,and effectively report the relevant alarm information of water level changes when the water pump is abnormal or the water inflow from the collection well is abnormal.It promptly reminds the operators to conduct accident analysis and handling,striving for remote and on-site accident handling time,timely discovering equipment abnormalities,and avoiding the occurrence of water flooding equipment accidents.
