摘要 伊敏发电厂的 5 0 0MW汽轮发电机组的本体设备是一流的 ,但其自动调节系统是不完善的。就其低加组及除氧器水位自动调节系统而言 ,按其原设计的方案是无法投入自动的。经过很长时间的努力 ,对这些系统进行全部的改造 ,现在已经全部投入自动调节 ,而且有极强的负荷适应能力 ,适应范围从 0~ 5 0 0MW。 The 500MW turbo-generator unit running in Yimin Power Plant was manufactured by Leningrad Metal Works. The main frame equipment of this unit was first-class, but its automatic regulating device was not perfect. For example low-pressure heater and deaerator automatic regulators could not be put into automatic operation according to original design scheme. Elaborate retrofits have been made for these devices/systems and by now they can run in full automation, and consequently with satisfied adaptability when load varying from 0 to 500MW.
