三峡右岸电站压差测量系统选用了雷达水位传感器及气泡式压力水位传感器,通过测量拦污栅前后的水位,采用差分方法计算出每台机组的压差值,从测量系统结构、传感器选型、通信组网、压差测量计算等方面阐述了压差测量系统。该系统自2008年11月运行以来,其测量的三峡右岸电站每台机组的拦污栅压差值与实际值一致,现担负三峡右岸电站的机组实际出力及出力预报,拦污栅前清漂等测量预警工作。
三峽右岸電站壓差測量繫統選用瞭雷達水位傳感器及氣泡式壓力水位傳感器,通過測量攔汙柵前後的水位,採用差分方法計算齣每檯機組的壓差值,從測量繫統結構、傳感器選型、通信組網、壓差測量計算等方麵闡述瞭壓差測量繫統。該繫統自2008年11月運行以來,其測量的三峽右岸電站每檯機組的攔汙柵壓差值與實際值一緻,現擔負三峽右岸電站的機組實際齣力及齣力預報,攔汙柵前清漂等測量預警工作。

We have chosen radar water-level sensor and bubble pressure water-level sensor for the pressure difference measurement system of Three Gorges Right Bank Hydropower Plant. These water-level sensors can accurately measure the pressure difference between front and back of dirt-proof grid of each unit. And the system has been operating since November, 2008. The measured pressure difference value of dirt-proof grid of each unit is the same as actual value. The system is responsible for job of unit power output, output prediction, water-saving for increasing generation, floater removal, ete, for Three Gorges Right Bank Hydropower Plant.
