The units with IP cylinder starting have been widely used in recent years

among them

the 330 MW units manufactured from Beijing Heavy Electric Machine Works being in the majority

the others being 600 MW units manufactured by East China Turbine Works.The features of control mode in IP cylinder starting for above-mentioned two kinds of units have been analysed and compared

results show that the manupulation in IP cylinder starting operation for 300 MW units manufactured from Beijing Heavy Electric Machine Works is simple

enhancing the automation level of said units

while in IP cylinder starting of 600 MW units manufactured from East China Turbine Works

there isn't clear requirement to load for cylinder change-over

boasting stronger suitability.
