Heating index evaluation method and system for turbine machine room in million kilowatt unit nuclear power station

Abstract

The invention discloses a heating index evaluation method and system for a turbine machine room in a million kilowatt unit nuclear power station. The method comprises the following steps: inputting a simulation parameter according to a heating and ventilation standard of a thermal power plant or a preset heating index table, and the simulation parameter comprises the unit capacity and a heating index corresponding to the unit capacity; building various heating index modules, conducting data fitting to the simulation parameters respectively, and computing the fitting coefficient; judging the best module according to the fitting coefficient, and conducting evaluation according to the field unite equipment parameter. Through the adoption of the method and system provided by the invention, tedious computing of a production drawing is overcome, heating evaluation is realized fast and conveniently, and the technique blanking is filled.

Description

technical field [0001] The invention relates to the heating, ventilation and air conditioning design technology of a thermal power plant, in particular to a method and system for evaluating the heating heat index of a steam turbine room in a nuclear power plant with one million units. Background technique [0002] A few days ago, my country clarified for the first time the strategic position of nuclear power in the national energy structure, determined the policy of "actively promoting the construction of nuclear power", and pointed out the direction for the development of nuclear power. Nuclear power construction has entered a new stage of rapid development, which indicates that my country will set off a wave of nuclear power construction, and more regions will build nuclear power plants. From the geographical point of view, the nuclear power plants that have been built to generate electricity in my country are located in the relatively warm southern and central regions. Ho...
