【摘要】 本文紧密结合目前我国电力体制改革对独立发电厂经济性方面的要求与挑战，对火电机组运行与维修的经济性进行了比较深入的分析。作者利用了常规热平衡法、热经济学方法以及电厂节能潜力诊断的理论这些较先进的理论方法，对锦州发电厂六号机组进行了分析计算，并将其应用于机组性能在线监测与诊断系统中，对系统的功能及方案进行了的详尽介绍。在对单元机组经济性分析的基础上，进一步对全厂范围的经济运行进行了探讨，着重对全厂各台机组的负荷最优分配问题进行了研究，分别采用等微增法与非线性规划两种方法进行了实例分析与计算。最后，利用技术经济学的基本理论与方法对电厂维修的经济性进行了分析。更多还原

【Abstract】 At present, the electric power system of China is under reforming and deregulating. It provides the independent power plant owners with the challenges of improving their economies. For the purpose of this, the economies of operation and maintenance of a power plant are studied in the thesis. Some advanced theories, such as the traditional heat balance method, thermoeconomics method and the energy conservation potential diagnosis, are adopted to analyze the economy of a 200MW power generating unit installed in Jinzhou power plant. The on-line performance monitoring system is developed. The functions and key technology ideas are introduced in detail. Based on the performance analysis for a power generating unit, the method of dispatching loads during different units in the whole plant are studied. We utilize two methods to dispatch the loads, the equivalent differential increase method and the dynamic planning method. In the end, the basic theories of engineering economics are used to optimize the maintenance cycle in order to improve the economy of a power plant.更多还原
