A Method for Energy Efficiency Evaluation of Ultra-low Emission Environmental Protection Island in Coal-fired Power Plants

Abstract

The invention relates to an energy efficiency assessment method for a coal-fired power plant ultra-low emission environmental protection island, which comprising the steps of firstly proposing a system operation energy efficiency assessment method in allusion to characteristics of a system to be assessed by combining relevant operation information and data, building an energy consumption calculation model for a coal-fired power plant environmental protection island system, setting an energy efficiency assessment index with an operation effect of the environmental protection island system beingconsidered, comprehensively analyzing and assessing the operation energy consumption level of the environmental protection island system on the whole, focusing analysis and assessment for main energyconsumption equipment in each subsystem and power utilization conditions of the system at the same time, acquiring influence laws of different factors for the energy consumption of the system according to a variable control method on the basis, and putting forward an optimized energy-saving operation control strategy in allusion to actual operating conditions of the power plant. According to theinvention, assessment analysis can be performed on operation energy consumption characteristics of the coal-fired power plant ultra-low emission environmental protection island system, the energy consumption characteristics of the environmental protection island system can be comprehensively analyzed in detail, and a reference is provided for decision making of the operating personnel and the management staff of the power plant.

Description

technical field [0001] The invention belongs to the fields of energy, environmental protection and information technology, and in particular relates to an energy efficiency evaluation method of an ultra-low emission environmental protection island of a coal-fired power plant. Background technique [0002] Pollutants produced by coal combustion are an important cause of my country's current severe air pollution problems, and the coal-fired power generation industry consumes more than half of my country's coal, and the coal power industry is one of the main sources of air pollutant emissions in my country. In order to control the emission of air pollutants from coal-fired power plants, the Ministry of Environmental Protection recently promulgated the "Emission Standards of Air Pollutants for Thermal Power Plants" (GB13223-2011), which stipulates that the emission concentration limits of sulfur dioxide, nitrogen oxides and particulate matter for coal-fired units are 100mg / Nm 3 ...

AI Technical Summary

Problems solved by technology

Therefore, the traditional method can only count the operating energy consumption of some key equipment, and it is difficult to conduct a detailed and comprehensive analysis of the operating energy consumption of the ultra-low emission environmental protection island system, and it is also difficult to reflect the dynamic energy consumption characteristics. It is necessary to develop a system that can fully reflect the environmental protection island Evaluation method of system energy consumption characteristics and dynamic energy consumption information
