Embodiment Construction
[0015] The present invention will be further described in detail below in combination with specific embodiments.
[0016] Taking a 300MW heating unit as an example, the electricity price was 0.36 yuan / kw.h when the feasibility study was approved, the evaporation capacity of the boiler was 897.1t / h under rated working conditions, the power generation of the steam turbine was 300008.1kw, and the heat consumption rate was 7872kJ / kw.h. The boiler efficiency is 93%, the pipeline efficiency is 99%, the power consumption rate of the same type unit is 5.2%, and the unit price of standard coal is 700 yuan / ton.
[0017] 1. Calculate boiler fuel cost and power generation revenue under rated working conditions:
[0018] Coal consumption for power supply
[0019] boiler fuel cost
[0020] Power Generation Revenue
[0021] 2. Under rated heating conditions, the evaporation capacity of the boiler is 897.1t / h, the power generation of the unit is 213208kw, and the heat supply D=1310.5...

The invention discloses a method for adjusting centralized heating price of a heating unit based on thermal and electronic product price linkage. The method comprises the following steps of: knowing electricity price, calculating a boiler fuel cost as A, and generating income as B when the steam generated by a boiler is all used for generating; calculating the generating income as C and heating load as D when the steam quantity of the boiler is constant (namely the boiler fuel cost is constant) and the unit is simultaneously used for generating and heating; calculating the heating gains with a formula of B-A-C, and calculating the heat price with a formula of (B-A-C) / D; calculating the electricity price by adopting delay electricity price, and repeating the steps, and marking the calculated heat price as M0; and calculating the electricity price by adopting actual grid purchase price, and marking the heat price obtained by repeating the steps to calculate as M1, wherein an adjustment range x is M1 / M0. By adopting the heat price adjustment method, the heating positivity of the heating unit can be protected to a largest extent; the gains of the heating unit are not damaged caused by increasing the heating quantity; and a reference frame for adjusting the heat price can be provided for government departments.
Description
[0001] technical field [0002] The invention relates to a price adjustment method for centralized heat supply of heating units based on price linkage of heat and electricity products, which is suitable for reference when adjusting heat supply pricing or formulating relevant compensation measures by the government. Background technique [0003] The heat supply unit can provide heat energy and electric energy at the same time, and its heat and electricity cost sharing calculation has been carried out in accordance with the "Opinions on the Implementation of Cost Accounting of Electric Power Industry Enterprises", that is, the "heat method" is used for calculation. This method is a typical "returning benefits to electricity", and all the economic benefits brought by cogeneration are assigned to power generation. The coal consumption of power supply calculated from this is lower than that of the main unit of the power grid, resulting in the illusion that power generation makes m...
