Performance Optimization Of The Auxiliary Equipment And Auxiliary Equipment System In Power Plant

The performance optimization of the auxiliary equipment, auxiliary equipment system and pipe network system in power plant are studied and analyzed in this thesis by applying the dynamic program, Agent etc. The aims of the optimization are to reduce the auxiliary power rate. The main concerns of this thesis are as follow:Firstly, the measuring methods, the real-time performance tests are discussed on the basis of the standard performance. In order to get the exact flow, the static- differential-pressure method is put forward. At the same time, the briefed mathematic models are used to optimize the auxiliary equipment performance. Secondly, the operation performance and the stability of the auxiliary equipment are analyzed according to the characteristic and some rules are given. And then regulation styles are compared so as to select the energy-saving equipment and system. Thirdly, as main energy-consumption units in power plant, the performance optimization of the pumps and fans are carried out. For getting good performance optimization consults, the important mathematic models based on dynamic program are put forward about the rotational speed and adjustable vane pumps and fans. At the same time, Agent and multi-Agent are applied, thus make the performance optimization system manage easily and use conveniently.Fourthly, for developing the all network performance, the forms and the structures of the air-inlet room, the rectifying devices, the chimney, the duct, the three-way duct, the inlet and outlet styles, etc, are improved. Thus the performance of the auxiliary equipment, auxiliary equipment system and pipe network system in power plant has been optimized.
