Problems solved by technology
Although this method is simple to operate, it does not take into account the mutual influence between the various systems and the weight of different influencing factors, so it cannot reflect the comprehensive operating cost of the unit after the ultra-low emission transformation.

Embodiment Construction
[0025] The present invention will be described in further detail below in conjunction with the accompanying drawings.
[0026] Such as figure 1 As shown, a method for evaluating the cost index of a thermal power generation unit ultra-low emission system provided by the present invention comprises the following steps:
[0027] First, establish the evaluation parameters of the evaluation model. The comprehensive cost of the ultra-low emission system of the thermal power generation unit is expressed as A; the actual operating cost of the unit is expressed as B, and the factors affecting the cost are: power supply coal consumption cost, desulfurization cost, denitrification cost, dust removal cost, water treatment cost, personnel Costs, denoted as M, L, X, C, S, R, respectively.
[0028] Secondly, calculate the correlation of each influencing factor to the comprehensive cost, and use the typical gray correlation analysis method to calculate, as follows:
[0029] 1. Determine th...

The invention discloses a cost index evaluation method for an ultra-low emission system of a thermal generator set, and aims at the limitation of an existing energy consumption and operation cost evaluation method. The method comprises the steps that firstly, influence factors influencing the comprehensive cost of the thermal generator set are counted, wherein the influence factors mainly comprisethe actual operation cost, the power supply coal consumption cost, the desulfurization cost, the denitration cost, the dust removal cost, the water treatment cost and the personnel cost and serve ascalculation basic parameters for establishing a model; secondly, calculating is conducted to obtain the influence weight of each influence factor on the comprehensive cost in combination with a mathematical statistics method of multi-factor analysis; and finally, a set of model for evaluating the system operation cost after ultralow emission transformation of the thermal generator set is established on the basis of a multi-objective decision analysis Topsis method, evaluation indexes and a method for evaluating the system operation comprehensive cost after ultralow emission transformation areobtained, big data analysis is combined according to conditions such as different types of units and regions, and the evaluation model is continuously optimized and perfected.
Description
technical field [0001] The invention belongs to the technical field of comprehensive operation cost evaluation after ultra-low emission transformation of a thermal power generating set, and in particular relates to a cost index evaluation method for an ultra-low emission system of a thermal generating set. Background technique [0002] In recent years, with the gradual strictness of environmental protection emission standards, most of the coal-fired thermal power generation units in the country have undergone ultra-low emission transformation to meet the emission requirements of nitrogen oxides, sulfides, dust and waste water, and further reduce Unit energy consumption. As a complex hybrid system composed of multiple single systems, the thermal power generation unit is not isolated, but closely related to each other. Therefore, it is necessary to adopt a systematic and comprehensive evaluation method for the evaluation of the operating cost of the thermal power generation u...
