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

The invention provides an energy efficiency analysis method of a generator set. The method comprises: acquiring generator set parameters, set performance target value and actual values; calculating external condition deviations according to boiler actual coal consumption, current environment temperature, turboset circulating water temperature, turboset heat-supply power generation ratio and turboset power generation capacity of the generator set parameters; respectively calculating a boiler efficiency deviation, a turboset efficiency deviation and a station service power consumption rate deviation through a boiler performance test, a turboset performance test and station service power consumption rate testing performance test under multiple working conditions, and calculating a device performance deviation according to the boiler efficiency deviation, the turboset efficiency deviation and the station service power consumption rate deviation; calculating expected values of set actual operation according to generator set design parameters, the external condition deviations and the device performance deviation; and respectively calculating difference values between the expected values and the target values and difference values between the expected values and the actual values, and calculating generator set energy efficiency according to preset weights and corresponding membership functions of the two types of difference values.

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...
