Key Control Strategy of Feed Pump Trip RB of 600 MW Supercritical Power Generation Units

Aiming at the supercritical power generation units produced by Shanghai Electric Generation Group,several key points about feed pump trip are analyzed,including stabilizing the combustion system to guarantee the boiler combustion,controlling the fuel-to-water ratio to keep proper steam-gas temperature of outlet of the waterwall and steam-water separator,starting the spare feed pump and reducing the load pressure of steam-driver pump etc.
