【摘要】：變頻循環(huán)水泵通過改變轉(zhuǎn)速來調(diào)節(jié)循環(huán)水量是火電廠冷端系統(tǒng)優(yōu)化的一個重要方面,而變頻循環(huán)水泵的功耗計算又是其中重要的一環(huán)。在分析變頻循環(huán)水泵功耗傳統(tǒng)算法缺陷的基礎(chǔ)上,提出單臺變頻循環(huán)水泵功耗計算模型和兩臺變頻循環(huán)水泵并聯(lián)運行功耗計算模型,使計算結(jié)果更加準(zhǔn)確,為火電廠循環(huán)水泵的變頻節(jié)能提供準(zhǔn)確的數(shù)據(jù)支撐,對冷端系統(tǒng)的優(yōu)化運行具有一定的指導(dǎo)意義。
[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.
