Calculation of Starting Currents and Losses for Damper Bars of Pumped Storage Machines by SFC
【摘要】 针对用静止变频器起动的抽水蓄能电机,建立了变频起动时的阻尼回路多回路数学模型,对其起动的自然换流过程进行了数字仿真,得到起动过程中各个阻尼条电流和损耗的分布,并以某电机为例做了实例计算.
【Abstract】 For the pumped storage machines started by static frequency converter(SFC),the mathematical model of multi-circuits is established.Then the mathematical simulation of static frequency converter starting is carried out by MATLAB,and the transient currents and losses of the damper bars are calculated.Finally,a sample machine is given as the example.
