Embodiment Construction

[0032]The present invention will be further described below in conjunction with the accompanying drawings.

[0033] An energy efficiency evaluation method for industrial field equipment, which uses the artificial neural network-based probabilistic energy efficiency evaluation method for the evaluation of the energy efficiency of three-phase asynchronous motors with limited industrial field parameter measurement, as follows.

[0034] (1) Observing energy efficiency: check the equipment nameplate, according to the equipment model and factory rated power η N , check the national standard energy efficiency limit value and energy efficiency grade standard of this type of equipment, and judge whether the equipment belongs to the high-efficiency equipment stipulated by the state; conduct economic evaluation of energy-saving transformation and replacement transformation of non-efficient equipment.

[0035] For example: the nameplate parameters of the three-phase asynchronous motor are...

Abstract

The invention discloses an industrial field equipment energy efficiency evaluation method. The method is based on industrial field equipment operation data acquisition, considers limitation of industrial field online data acquisition, and provides four online equipment energy efficiency calculating methods suitable for different conditions. The method mainly based on an equipment efficiency test method in national standards, equipment physical models are recognized through a manual neural network, and mathematical statistical theories are used for error analysis of results to achieve online evaluation of industrial field equipment energy efficiency. Compared with the existing methods, the method considers limitation of industrial field online data acquisition and has more actual operationability. Compared with common experience methods and evaluating methods, the method is more scientific, evaluation precision is guaranteed, and accordingly industrial enterprises can master equipment operation energy efficiency in real time, energy conservation and consumption reduction are achieved, power utilization is optimized, power cost of enterprises is lowered, and implementation of the national energy conservation and consumption reduction policy is facilitated.

Description

technical field [0001] The invention relates to a method for evaluating the energy efficiency of industrial field equipment, which belongs to the fields of energy technology and electrical engineering. Background technique [0002] In order to further strengthen power demand-side management and implement the national energy-saving and emission-reduction strategy, six ministries and commissions including the National Development and Reform Commission and the Electricity Regulatory Commission jointly issued the "Power Demand Side Management Measures". In order to better complete the evaluation indicators of the method, promote the transformation of my country's demand side management from load management to energy efficiency management, and promote the development of contract energy management and energy-saving service companies in my country, scientific and accurate assessment of equipment energy efficiency is an important link. . The state has successively promulgated standa...
