Problems solved by technology

[0003] The steam generated by the cogeneration unit boiler is not only used for power generation, but also for external heating by means of steam extraction and back pressure. The standard coal consumption rate for power supply (hereinafter referred to as heating coal consumption) cannot be directly measured by belt scales. The value and other data are obtained by using the positive balance method, which can only be calculated according to the external heat supply, boiler efficiency, and pipeline efficiency, or the method of artificially dividing the standard coal volume of the boiler by using the power generation and heat supply sharing ratio.

Abstract

The invention relates to the technical field of power plant thermoelectric cost apportionment calculation, in particular to a heat supply unit thermoelectric cost apportionment method. According to the power supply and heat supply cost allocation method provided by the invention, factors influencing coal consumption calculation, such as heat supply meter metering errors and fire coal heat value test errors, are comprehensively considered, reasonable allocation is carried out in heat supply and power generation links, and auxiliary power, heat supply and power generation cost and the like can be allocated by utilizing a heat supply ratio; various methods for calculating the heat supply cost of the current domestic heat supply unit are fully combined, and the cost allocation calculation method is perfected and corrected; the result meets the actual conditions of various types of units, and the method is extremely high in universality and has good expansibility.

Description

technical field [0001] The present invention relates to the technical field of thermal power cost apportionment calculation in power plants, and more specifically, relates to a thermal power cost apportionment method for heating units. Background technique [0002] The fuel consumption of cogeneration units is not completely consistent with the power generation capacity: part of the fuel consumption of this type of unit is used for grid power generation, while the other part is used for heating. The accuracy of the actual power consumption data of cogeneration units directly affects the electricity market quotation strategy and profitability of this type of units. Therefore, it is necessary to provide scientific and effective calculation methods for the "coal consumption calculation of power supply" of cogeneration units. [0003] The steam generated by the cogeneration unit boiler is not only used for power generation, but also for external heating by means of steam extract...
