Power generation thermal efficiency calculating method and power generation thermal efficiency calculating system of thermal power plant

Abstract

The invention discloses a power generation thermal efficiency calculating method and a power generation thermal efficiency calculating system of a thermal power plant. The method comprises the steps of collecting fossil fuel consumption of the thermal power plant from an energy balance list of a target country; collecting the power generation amount corresponding to the fossil fuel consumption from the energy balance list; and dividing the heat corresponding to the fossil fuel consumption by thermal equivalent of the power generation amount, and calculating to obtain the power generation thermal efficiency. Through the technical scheme, the energy balance lists of the countries in the world are effectively utilized, the power generation thermal efficiency of the thermal power plants of 130 countries in the particular year (lagged behind the current year for 2 years, for example, the power generation thermal efficiency of the main countries in 2013 can be calculated by adopting the energy balance lists in 2015) can be effectively calculated, and the lagging time in the aspect of timeliness can be shortened, so that the blank of shortage of the method for calculating the power generation thermal efficiency of the thermal power plants of 130 countries in the world at present can be filled.

Description

technical field [0001] The invention relates to the technical field of statistical analysis of energy and electric power, in particular to a method and system for calculating thermal efficiency of power generation in a thermal power plant. Background technique [0002] Today, the thermal efficiency of a thermal power plant refers to the ratio of the heat equivalent of electric energy produced by a thermal power plant to the heat consumed for power generation. Obviously, improving the thermal efficiency of thermal power plants can reduce the fuel consumption of thermal power plants, reduce the emission of pollutants such as sulfide and nitrogen oxides and greenhouse gas carbon dioxide per unit of power generation, and improve the economic and ecological benefits of thermal power plants. [0003] Although there are generally recognized calculation formulas for the thermal efficiency of thermal power plants, due to the lack of data and method support, there is currently no effe...
