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。
The differential pressure measuring system of the Three Gorges right bank power plant selected the radar water level sensor and the bubble pressure water level sensor to measure the pressure difference of each unit by measuring the water level before and after the trash rack and from the measurement system structure, sensor selection, Communication network, pressure measurement and calculation of the differential pressure measurement system described. Since the system was put into operation in November 2008, the measured value of the trash rack pressure difference per unit of the Three Gorges Right Bank Power Station has been in line with the actual value. Now it is responsible for forecasting the actual output and output of the units of the Three Gorges Right Bank Power Plant, Such as measurement and early warning work.
