Thermal Power Plant Master Control Unit Online Energy Loss Analysis And Thermal-economic Forecasting Model

Energy sources are important matter base for human life and social development. Coal is the primary fuel for generating electricity and thermal power in our country. Energy conservation is an important task in electrical industry. The performance monitoring system has appeared in the coal power house from ninety years of twenty century. Using the real time data of the producing process, decision-making and analysis can be offered for the safety and economical run. The analysis system about heat economy and indexes of unit performance and is very useful for the corporation. The running can be optimized for its guidance. The running efficiency and supervising can be improved in more range and deep arrangement. It is an assistant tool for the operator. So the integrated economical benefit can be increased and energy conservation of the power house comes true in finally.Energy consumption online analysis and thermal economics index of the thermal power house are studied in this thesis. The main work is to build interrelated models which make preparations for the relevant system software. It has important meaning for the thermal power house, and it would do enormous contribution to the thermal power and energy source project. In this field, the models of single unit have been built, but no one about the steam and generating units in centralizing pipe form has been found. In this thesis, the steam and generating units in centralizing pipe form is the research object, and thermo-electricity supplying together and requirement how to advance thermal economics index are considered. The analysis of thennal economy and inspecting system of performance can be studied as follows:1 Analyze the actuality of energy consumption online analysis and economical running in the thermal power house, realize the development of this field, and find the good method to fit the thermal power house.2 Analyze running mode of the steam and generating units in centralizing pipe form, build true model of it, and realize the fine load proportion among the boilers and turbines.3 Analyze the thennal efficiency of every part of the units, build the contact between every parameter and thermal efficiency, and build the calculating model of them.4 Analyze the differ heat between thennal supply and generate electricity, build the economics models of them, and introduce a new economics index which can calculate them fully.
