The Area Choosing And Site Optimizing In Developing Of Electric Net And Power

Large-scale thermal power plant construction project is a system engineering costs enormous.It concern all respects of national economy and people's lives, so the corresponding site selection work includes a great deal of technology and economic key element. With the electric system reform .Site selection of power plant has already carried out a balance transition from country planning to many generate electricity Company's independently competition. In order to obtain corresponding optimum seeking of site of factory sciencely and rationally, this text tries to research and develop one set of methods to optimize and appraise the method at the electric site of thermal power factory, which is suitable under electric market competition conditions and have effective reality. As to the select project Chinese Datang group company working for the a electric net, this literary uses the analytical method of the system engineering and proposed the optimizing method of fuzzy Judging and price combining,this make the site selection course more rational and effective . As a result, the factory will have very strong fighting for strength and operation benefit unexpectedly after the power plant goes into operation.Firstly, concern to the apprasing of the area chosen, directing against different areas inside the province ,the text change the traditional method into comparing much more factory-founding conditions, for example, fuel, transportation, environmental protection, water resource and so on, but not just fuel and net transition. Then it adopts the method that the expert gives a mark to get the fuzzy quantization of the mainly external condition of factory founding. By collecting the quantization results, we can get a fuzzy arranging result of different areas, thus to find the most suitable site.Secondly, after selecting the site,the text change the traditional price principle of power project– "supply according to the demand" and "cost accounting the price", and propose a power appraising method based on the studying of different estimating price (the price element) in each area. Take a deep comparing of the technological condition in different site of factory in the confirming area ,obtain on the foundation of the comparatively accurate data by norm through the power industry, then assume the reasonable investment return and recovery service life, calculating the cash flow of every year in the life-span of operation and convert it to the current value of initial year, then estimating reasonable price of different site by regarding the current value as zero, and then taking price of electricity as the core to judge the competitiveness of the project, as a result, the optimum site of factory that meets condition of electric market is found.The optimization method that this text has put forward has actual effectiveness and project use prospect. It is suitable for every large generate electricity Company to study as reference about the site-selecting project of thermal power plant.
