Embodiment Construction

[0123] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0124] 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 man...

Abstract

A method for analyzing the energy efficiency of a generator set, comprising: acquiring generator set parameters, and a target value and an actual value of the set performance; calculating an external condition deviation according to the actual boiler coal burning amount of the generator set parameters, a current ambient temperature, a turboset circulating water temperature, a turboset heat and power ratio and a turboset generating capacity (S102); under a plurality of conditions, calculating a boiler efficiency deviation, a turboset efficiency deviation and a power consumption rate deviation by a boiler performance test, a turboset performance test and a performance test for testing a power consumption rate, respectively, and according to the boiler efficiency deviation, the turboset efficiency deviation and the power consumption rate deviation, calculating a device performance deviation (S103); according to a generator set design parameter, the external condition deviation and the device performance deviation, calculating a normal value of the set in the actual operation (S104); and respectively calculating the differences between the normal value and the target value and the actual value, and calculating the generator set energy efficiency according to preset weights and corresponding membership functions of the two differences (S105).

Description

technical field [0001] The invention relates to an energy efficiency analysis technology for a coal-fired generating set, in particular to an energy efficiency analysis method for a generating set. Background technique [0002] As society's demand for electricity is getting higher and higher, how to improve the energy efficiency of generator sets has become a concern of people. [0003] From the perspective of energy conversion, the energy conversion efficiency η of the generator set E It is the product of various processes such as boiler and steam turbine, expressed in the following formula: [0004] n E = η B ·η P ·η T ·(1-W S / W G ) [0005] Among them, η B is the thermal efficiency of the boiler, η P is the pipeline efficiency, η T is the turbine efficiency, W S is the self-consumption power, W G for power generation. [0006] It is usually customary to use power supply coal consumption b to represent the energy conversion efficiency η of a coal-fired power...
