摘要
众所周知,能源问题一直是我国目前面临的首要问题,它关系到我国经济发展的步伐。因此,节约能源在我国经济发展进程中就显得尤为重要。
    本文从节能的角度入手,充分考虑我国的国情,分析探讨了目前火电厂大容量水泵的性能监测与运行优化问题。
    首先结合山东省石横电厂的实际情况,建立了较为完整的给水泵性能监测数学模型,开发了相应的在线计算应用软件。根据给水泵的设计参数绘制了给水泵的性能曲线,并根据现场的实测数据对现场实际运行工况点进行实时跟踪记录,实时地反映了给水泵的实际运行工况点。
    然后又结合某电厂循环水系统优化运行方式的改造,给出循环水系统变速泵并联运行优化改造方案。通过建立变速泵并联运行时的优化数学模型,并编制了相应的优化运行程序。
As well known, energy is the first chief problem in our country, it directly influences on our economic development. As a result, saving energy is very important in the process of economic development .
    This paper explores performance monitoring and operating optimization of water pump for large unit for saving energy in power plant.
    First of all , we set up the better feedwater pump performance monitoring mathematics model in the shi heng plant of shandong province , and developing this model calculating software. We also draw the feedwater pump performance curve by these design parameters, doing the practical tracking record by real time measuring data. Therefore, we have the satisfying operating condition by the feedwater pump.
    And then , this parallel connection operating optimization reconstruction project is put forward in variable speed pump of circulating water system , finally we found the optimization mathematic model and workout its optimization operation program.
