In addition, the requirement of feedwater control index specified in domestic unit acceptance standard is low than one in contract
另外，國內投產驗收規定中的給水控制指標也沒有合同要求嚴格。 -
With the development of process control technology the requirements of automatic control level for generating unit are increasing rapidly. full range feedwater control system is one example
隨著控制技術的不斷發展，對發電機組自動化水平的要求也越來越高，全程給水自動控制系統就是其中之一。 -
During unit startup and load is lower than 15 %, drum level is controlled by feedwater control valve, feedwater pump remains at minimum safety speed ; when load is between 15 % and 25 %, feedwater control valve is closing at fixed speed determined by function module, main motor - operated - valve is opened automatically, control mode of drum level is transferred to feedwater pump automatically and bumplessly ; when load is between 25 % and 50 %, control valve is closed fully, and main motor - operated - valve is open fully, drum level is controlled by one pump ; when load is more than 50 %, first pump is kept in operation, second pump is putting into operation automatically and
在機組啟動、沖轉及機組並網至15 %負荷階段，給水泵維持在最低安全轉速下運行，汽包水位由低負荷給水調節閥自動控制; 15 %至25 %負荷階段，給水調節閥由函數模塊按照一定的速率自動平滑關閉，主給水電動門自動打開，汽包水位控制方式自動無擾切換為給水泵自動控制;負荷在25 %至50 %階段時，給水調節閥已完全關閉，主給水電動門已完全打開，水位控制已全由單臺給水泵承擔;負荷大於50 %后，在第一臺給水泵運行的同時，第二臺給水泵自動無擾投入。
