| The five power generation corporations have come into existence, which is thought to be the symbol representing the commencement of the internal electric power supplies market and the termination of conventional monopoly. According to the "the plants and the power grids operate independently"policy, those power generation plants will face furious competition in the bidding market. Therefore, the organization of electric power generation based on the market economical law, the accurately analysis of plant's costs, and the offering of rational bidding prices in time are all urgently needed to have a thorough investigation. Focusing on the power generation side, this dissertation aims to build a series formulae that can calculate the relationships of the facilities life, reliability and the optimum benefit. After analyzed the main factors affecting the generation's life, this paper presents the PLL(Proportional Life Losing) equivalent aging model of turbo-generator. Based on this model, the single optimum benefit model is presented by using the Cost-Benefit analyzing method firstly. Secondly, after synthetically considered the various factors, such as operation states, operation costs, maintenance interval and its cost, reliability parameter and the protection requirement of environment and so on, the optimum benefit model of generation unit and the whole plant is presented. Because of the model that has been presented is a nonlinear-optimization problem and the data is not well integral, the fuzzy number that belongs to Fuzzy Set Theory is imported to abbreviate the model. And we get the standard form that the Sequential Quadratic Programming (SQP) requires. At last, by using the optimization algorithm contained in MATLAB Optimization Toolbox and taking a domestic firepower plant as an example, some meaning conclusions are drawn. Both the model and the conclusions can provide fundamental support for generation facilities'life management and the maintenance mode.
