The invention relates to a method for online efficiency monitoring of a circulating water pump in a thermal power plant, which comprises the steps that a collection module collects real-time operation data of the circulating water pump in the thermal power plant; a real-time data collection network recodes and isolates the received data; a processing module determines a scope and works out an average of original operation data of the circulating water pump in the thermal power plant; a calculation module works out current lift, effective power and efficiency of the circulating water pump in the thermal power plant; a data storage server completes classification and storage of the data; and the efficiency and historical operation data of the circulating water pump are shown on a display screen by forms and curves. In the form of charts and the history curves, the method for the online efficiency monitoring of the circulating water pump in the thermal power plant provided by the invention reflects the efficiency and historical operation data of the circulating water pump in the thermal power plant, helps operation staffs master the efficiency of the circulating water pump in the thermal power plant and provides references for economic operation of a circulating water pump system in the thermal power plant.
Description
technical field [0001] The invention belongs to the technical field of thermal power generation energy saving, in particular to an online monitoring method for the efficiency of a circulating water pump in a thermal power plant. Background technique [0002] The circulating water pump is one of the main auxiliary equipment of the thermal power generation unit, and its main task is to provide circulating cooling water for the condenser and other equipment that needs to be cooled. However, the efficiency of circulating water pumps in thermal power plants can only be obtained through experimental calculations, and there is no real-time monitoring method for circulating water pumps in thermal power plants, resulting in the lack of necessary technical support for the economical operation of circulating water pumps in thermal power plants. Contents of the invention [0003] The object of the present invention is to propose an online monitoring method for the circulating water pu...
