火电厂模糊优化选址

随着电力市场化的进行,发电企业之间的竞争日益激烈。在新的形势下,如何对火电厂进行优化选址,以增强电网的安全和企业的竞争力,已成为电网和发电企业共同关注的问题。通过对众多选址因素的分析,建立了包括经济性、安全性、环保性和社会性指标在内的火电机组选址的完整优化指标体系;充分利用地理信息系统(GIS)的可视化功能,将整个选址区域划分为若干个连续单元,依照火电厂选址的可行性指标确定可行单元,并计算各单元指标数据;最后通过建立各单元的模糊识别模型,实现了整个区域内火电机组的优化选址。案例计算表明研究结果具有很强的适用性,它对优化电源选址具有重要意义。

The Fuzzy Optimization of the Site Selection for Coal-fired Power Plants

With the implement of the power industry market reform, the competition among the power generating companies is becoming drastic increasingly. Under the situation, it has been the focus for both the power grid companies and the power generating companies that optimize the site selection of power plants in order to increase their security and competitive advantage. Based on the analyses of all the factors influencing the site selection of coal-fired power plants, the integrated indexes system including the performances of economy, safety, environment and society is established. The total site region is divided into many successive units by using the visible function of geography information system(GIS). The feasible units are determined and calculated according to the feasible indexes of site selection. In the end, the optimal site selection is completed by establishing the models of fuzzy recognition for each unit. It has been revealed that the research results have good applicability and are beneficial to optimize the site selection of coal-fired power plants.
