摘　　要：行星齿轮变频调速装置作为一种先进电动机调速节能技术,因其优良的可靠性已在能源环保工业电动机节能领域得到广泛应用。为定量分析其节能效果,基于能量平衡和质量平衡,针对某600 MW机组给水泵采用平行对比法(A液力耦合器传动调速,B行星齿轮传动调速)对给水泵进行性能评价。试验过程中,将两台给水泵组的功能倒换,但环境温度、入炉煤质等边界条件难免改变,两台给水泵组出力也会随之发生偏差。为此,引入一个新概念——泵水功耗系数,该系数可兼顾两台给水泵组的出力偏差,较准确地开展机组同负荷下的给水泵组能耗之间的横向对比及节能评价。试验表明:文中所提出的试验方法,可以实现对行星变频调速给水泵性能定量分析,为能源化工行业动力机械设备节能改造奠定基础。As an advanced motor speed regulation and energy saving technology,planetary gear variable frequency speed regulation device has been widely used in the field of motor energy saving and environmental protection industry due to its excellent reliability.In order to quantitatively analyze its energy saving effect,based on energy balance and mass balance,the performance evaluation of the feed water pump of a 600 MW unit was carried out using parallel comparison method(A hydraulic coupler drive speed regulation,B planetary gear drive speed regulation).During the test,the functions of the two feed pump sets were reversed,but boundary conditions such as ambient temperature and coal quality entering the furnace inevitably changed,and the output of the two feed pump sets would also deviate accordingly.To this end,a new concept-pump water power consumption coefficient is introduced,which can take into account the output deviation of the two feed pump units and more accurately carry out horizontal comparison and energy saving evaluation between the energy consumption of the feed pump units under the same load of the unit.The test shows that the test method proposed in this paper can realize quantitative analysis of the performance of the planetary frequency conversion speed regulating feed water pump and lay a foundation for the energy saving transformation of power machinery and equipment in the energy and chemical industry.
