Heat supply unit thermoelectric product cost measuring and calculating method and device and terminal equipment

Abstract

The invention provides a heat supply unit thermoelectric product cost measuring and calculating method and device and terminal equipment. The method comprises the steps: obtaining the total cost, thepower generation information amount and the heat supply information amount of a heat supply unit; establishing a virtual heat supply boiler model and a virtual straight condensing generator set model,determining a first equivalent cost of a virtual heat supply boiler under the heat supply information amount based on the virtual heat supply boiler model, and determining a second equivalent cost ofa virtual straight condensing generator set under the power generation information amount based on the virtual straight condensing generator set model; and taking the ratio of the first equivalent cost to the second equivalent cost as a thermoelectric cost distribution proportion, and determining the heat supply cost and the power generation cost of the heat supply unit based on the thermoelectric cost distribution proportion. According to the heat supply unit thermoelectric product cost measuring and calculating method and device and the terminal equipment, the cost measuring and calculatingreasonability and accuracy of the heat supply unit thermoelectric product can be improved.

Description

technical field [0001] The invention belongs to the technical field of cost calculation of thermoelectric products, and more specifically relates to a method, device and terminal equipment for cost calculation of thermoelectric products of a heating unit. Background technique [0002] A heating unit, also known as a combined heat and power unit, produces both heat and electricity. Since many costs such as fuel costs and fixed costs of the heat and electricity products of the heating unit are common, how to determine the respective costs of the two products to improve energy utilization has become an urgent problem to be solved. [0003] In the prior art, the calorimetric method is usually used to calculate the cost of thermoelectric products of heating units, that is, the cost of fuel consumed for heating is the same as that for direct heating of heating boilers, and the remaining fuel costs are classified as power generation costs. The main disadvantage of this method is t...

Problems solved by technology

The main disadvantage of this method is that the benefits and benefits of cogeneration are only allocated to electrical products, resulting in a high calculated heating cost, which does not fully reflect the heating advantages of cogeneration units, which is very unfavorable for cogeneration Promotion and application of technology
