摘要
近年来,利用调度自动化系统中CVT电压数据进行CVT在线监测的研究逐渐增多,在实践中也取得了不少成果,但由于CVT采样误差的原因,直接利用电压对比的方法进行监测会产生大量的误告警,需要大量的人工介入进一步甄别.文章利用CVT电压差值进行在线监测,可进一步提高监测报警的准确性,减少人工确认工作量.
Abstract
In recent years,the use of scheduling automation system of CVT voltage data for CVT online monitoring research gradually increased,in practice also made a lot of results,but due to the cause of CVT sampling error,directly using the method of voltage comparison for monitoring will produce a lot of alarm,need a lot of artificial intervention to further screening,this method,using CVT voltage difference online monitoring,can further improve the accuracy of the monitoring alarm,reduce the workload of manual confirmation.
