【摘要】：变频循环水泵通过改变转速来调节循环水量是火电厂冷端系统优化的一个重要方面,而变频循环水泵的功耗计算又是其中重要的一环。在分析变频循环水泵功耗传统算法缺陷的基础上,提出单台变频循环水泵功耗计算模型和两台变频循环水泵并联运行功耗计算模型,使计算结果更加准确,为火电厂循环水泵的变频节能提供准确的数据支撑,对冷端系统的优化运行具有一定的指导意义。
[Abstract]:It is an important aspect to optimize the cooling system of thermal power plant to adjust the circulating water by changing the speed of the variable frequency circulating pump, and the calculation of the power consumption of the frequency conversion circulating pump is an important part of it. Based on the analysis of the shortcomings of the traditional algorithm for power consumption of variable frequency circulating water pump, the power consumption calculation model of single variable frequency circulating pump and two parallel operation power consumption models of two variable frequency circulating pumps are proposed, which makes the calculation results more accurate. It provides accurate data support for the frequency conversion and energy saving of circulating water pump in thermal power plant, and has certain guiding significance for the optimization operation of cold end system.
