The invention provides a refinery enterprise self-contained power plant unit thermoelectric load distribution method, system and equipment. The method comprises steps of building a thermoelectric load distribution model based on the income and cost of power generation income, heat supply income, fuel cost and the like according to the steam supply characteristics of a refinery enterprise self-contained power plant header system and the petroleum coke fuel characteristics; a distribution scheme is given in real time through a planning and solving method, the self-contained power plant is guided to perform production scheduling, and benefit maximization of the self-contained power plant is met.
Description
technical field [0001] The invention relates to the field of energy saving and consumption reduction of self-provided power plants of petrochemical enterprises, in particular to a method, system and equipment for distributing thermoelectric loads of units of self-provided power plants of refining and chemical enterprises. Background technique [0002] The self-owned power plants of refining and chemical enterprises, as the public affairs department of refining and chemical enterprises, are often accounted for as an independent unit, and multiple boilers and steam turbines with small capacity are often used for main control power generation and steam supply. The steam supply is multi-quality, common There are ultra-high pressure, high pressure, medium pressure, and low pressure, and the production fuel is mostly petroleum coke. While satisfying external steam supply and ensuring the normal production of petrochemical process products, taking into account the various costs of ...
