Overwintering Practice of the Automatic Water Situation Monitoring and Reporting System of the Fengning Pumped Storage Power Station in Hebei
The area where the automatic water situation monitoring and reporting system of the Fengning Pumped Storage Power Station in Hebei is located has very low temperature in winter.In order to ensure the normal and safe operation of the power station,this paper tests the operation of the automatic water situation system under cold conditions in winter,observes and counts the voltage and patency rate of its each telemetry station under extremely cold conditions,and analyzes the daily minimum temperature process of the upper storage reservoir and the lower storage reservoir,the voltage process of telemetry stations and the influence of temperature on the voltage of telem-etry stations during the test period.The results show that the water situation monitoring and reporting system in Fengning can adapt to its cold conditions in winter,water situation data is timely and accurately reported during the test period,and that the average patency rate of telemetry stations reaches 98.8%,which can provide water situation information guarantees for the smooth operation of the Fengning Pumped Storage Power Station.
