摘 要:通过对某电厂一次风机变频器工作原理的介绍,在工频方式运行和变频方式运行时电流、有功功率、无功功率等数据的分析,表明变频器投入运行后可为负荷提供大量无功补偿、提高变频器输入侧功率因数,在降低的运行电流中无功分量较多,单纯以负载运行电流降低的数值作为变频器节能量的计算依据不准确。为变频器节能量计算提供实际数据。

Abstract: Through the introduction of the working principle of the once primary fan frequency converter in a power plant and the analysis of the current, active power, reactive power and other data during the operation of the power frequency mode and frequency conversion mode, it is shown that the frequency converter can provide a large amount of reactive power compensation for the load after being put into operation, improve the input power factor of the frequency converter. There are many reactive components in the reduced operating current, so it is inaccurate to simply take the value of the reduced load operating current as the calculation basis of the energy saving of the frequency converter. Provide actual data for energy conservation calculation of frequency converter.
Keywords: frequency converter; energy conservation; active power; reactive power; current
