Analysis Method of Objective Factors Affecting Energy Efficiency of Generating Sets

Abstract

A method for analyzing objective factors affecting the energy efficiency of a generating set, including: obtaining the design parameters of the generating set, the actual coal consumption of the boiler, the current ambient temperature, the temperature of the circulating water of the steam turbine set, the load rate, the heat supply and power generation ratio of the steam turbine set, and the temperature of the steam turbine set Generator unit parameters such as power generation; calculate the external condition deviation according to the actual coal consumption of the boiler, the current ambient temperature, the circulating water temperature of the steam turbine unit, the heat supply and power generation ratio of the steam turbine unit, and the power generation of the steam turbine unit; under multiple working conditions, pass Boiler performance test, steam turbine unit performance test and substation power rate test performance test to calculate boiler efficiency deviation, steam turbine unit efficiency deviation and substation power rate deviation; according to boiler efficiency deviation, steam turbine unit efficiency deviation and substation power rate deviation, calculate multiple Power supply coal consumption deviation under each working condition; generate equipment performance curves based on multiple load points and power supply coal consumption deviations; calculate objective factors under the current load based on external condition deviations and equipment performance curves.

Description

technical field [0001] The invention relates to a coal consumption analysis technology for a coal-fired generating set, in particular to an analysis method for objective factors affecting the energy efficiency of a generating set. Background technique [0002] As the society's demand for electricity is getting higher and higher, how to improve the power generation efficiency of generator sets has become a problem that people pay attention to. [0003] For a certain generator set, the final energy efficiency level it can achieve depends on three factors, namely: the design and manufacturing level of the generator set; the application conditions of the generator set; management application level. The management application level of the manager to the generator set is a subjective factor of the unit operation, which can be improved through the improvement of the operation management. The design and manufacturing level of the generator set, as well as the application condition...
