Embodiment Construction

[0016] The present invention will be further described in detail below in conjunction with the accompanying drawings and examples. The following examples are explanations of the present invention and the present invention is not limited to the following examples.

[0017] Example.

[0018] see figure 1 , in this embodiment, a real-time cost estimation method for a coal-fired power plant based on production and financial data, comprising the following steps:

[0019] 1. Data processing process: Obtain daily production and financial data of coal-fired power plants, divide cost data categories, divide real-time costs into fixed costs and variable costs, and divide fixed costs into depreciation expenses, financial expenses, employee salaries, material expenses, repairs Fees, fixed taxes, entrusted operation fees and other expenses, the variable costs are divided into fuel costs, purchased power costs, variable taxes and water costs, and the data is extracted into the divided data...

Abstract

The invention discloses a coal-fired power plant real-time cost measuring and calculating method based on production and financial data. The problem that a measuring and calculating method in the existing real-time cost measuring and calculating process is not comprehensive and has data errors is solved by utilizing daily production and financial data of a power plant. The calculation method comprises the steps of obtaining daily production and financial data of the coal-fired power plant; dividing cost data categories, dividing the real-time cost into fixed cost and variable cost, and extracting the data into the divided data categories; establishing a power supply coal consumption model, substituting power plant production data into the power supply coal consumption model to calculate toobtain a power supply coal consumption value, and substituting fuel price data and the power supply coal consumption value into the model to calculate to obtain a fuel cost value; establishing a real-time cost calculation model, and substituting production and financial data into the cost calculation model to obtain other cost values; and summing the change cost value and the fixed cost value toobtain a real-time total cost value. The calculation model is simple, clear and easy to understand and operate.

Description

technical field [0001] The invention relates to the technical field of cost measurement and calculation, in particular to a method for real-time cost measurement and calculation of coal-fired power plants based on production and financial data. Background technique [0002] The real-time cost is the cost consumed by the unit under a certain load within a certain period of time. The power spot market clearly requires power generation companies to perform real-time cost calculations according to the power generation of various units, so that real-time cost calculations can be scientifically applicable to the quotation and operation management of the power spot market. In recent years, many research institutions and manufacturers have conducted research on real-time costs. For example, "Thermal Economics Method for Cost Analysis of Thermal Power Plants" published in "North China Electric Power Technology" proposed a method of cost calculation using thermoeconomic theory to analy...
