Abstract

An analysis method for objective factor affecting generator set energy efficiency comprises the following steps of acquiring generator set parameters including generator set design parameters, boiler practical coal combustion amount, current environment temperature, turboset circulating water temperature, load rate, turboset heat supplying and generating ratio and turboset generation amount, calculating external condition deviation according to the boiler practical coal combustion amount, current environment temperature, turboset circulating water temperature, load rate, turboset heat supplying and generating ratio and turboset generation amount, calculating boiler efficiency deviation, turboset efficiency deviation and station service power consumption rate deviation according to a boiler performance test, a turboset performance test and a station service power consumption rate test under multi-work conditions, calculating net coal consumption rate deviation of the multi-work conditions according to the boiler efficiency deviation, turboset efficiency deviation and station service power consumption rate deviation, generating equipment performance curve according to multi-load points and net coal consumption rate deviation, and calculating objective factors of the current load according to external condition deviation and the equipment performance curve.

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...
