给定出力660MW机组最佳真空确定方法

The Method to Find Optimal Condenser Vacuum of 660MW Steam Turbine Generator Set as Output Unchanged

资源消耗最少、生产利润最大、发电或供电标准煤耗率最低等几种优化目标,均可应用于给定出力N660-17.5/537.8/540型单元机组最佳真空的寻优计算中。建立了该单元机组全面数学模型,编制了对应的C语言程序。根据其计算结果得出结论:采用"资源消耗最少"作为优化目标,有利于降低资源消耗和减轻环境污染;采用"生产利润最大"作为优化目标,虽有利于电力企业的经济运营,但相比之下则要浪费更多的资源。

Several optimal targets can be utilized in the searching for the optimal cooling water through the condenser of a steam generator unit set of N660 - 17.5/537.8/540 type as its electric output unchanged, such as resource consumption minimization, productive profit maximization, minimizing the special standard coal consumption for electric generation of a kilowatt hour and so on. A complete mathematical model and its application by C programming language for the unit set has been created to finish the optimal searching calculation. According to the calculation results, it can be seen that, the optimal target of resource consumption minimization is the best to reduce the energy consumption and abate environment pollution, and the optimal target of productive profit maximization is beneficial to economical running of an electric power enterprise, but more resources must be wasted in comparison with the optimal target of resource consumption minimization.
