摘要
研究了电力滤波器与直流电机调速系统6脉波可控整流器之间的相互作用,分析了当滤波器连接在换流变压器低压侧时对换相电流、触发角α、换相重迭角γ、功率因数、谐波电流等的影响,讨论了这些影响的实用计算方法,并与现场实测结导做比较,表明设计滤波器时需考虑相互作用的影响。
The interaction between filter and 6 pulse controlled rectifier of DC motor speed system are introduced. The effect of commutated current, commutated angle α, overlap angle γ power factor and harmonic currents etc. is analyzed when the filters is connected to low-voltage side of commutated transformer.This paper describes the practical calculating method of the changes and the test results at site. It is shown that the interaction must be considered in the design of fiher.
