The Scheme's Research Of Reforming Cycling Water Pump's Control System In Huaneng Pingliang Power Plant

Going on with the development of electric power industry and the reinforcing of energy saving sense, the cycling water pump's control system in HUANENG PINGLIANG POWER PLANT has couldn't satisfy the requirement of producing process and energy saving. In this thesis, the writer seriously analyzed the cycling water pump's control system in HUANENG PINGLIANG POWER PLANT from reliability, economic value, feasibility, and studied the application of Converting Frequency Machine, and then get a scheme at the end.By means of establishing a net of PLC and DCS, and controlling the cycling water flow by converting frequency machine to convert cycling water pump's rotation, the auto control level of HUANENG PINGLIANG POWER PLANT gets a extremely improvement, the requirement of energy saving is met too.
