在分析现有矿井提升机励磁系统结构的基础上,研究了控制系统调节器参数对励磁系统的影响。提出将PWM高功率因数整流器应用于同步电动机他励系统,代替传统的晶闸管励磁系统,减少了原有的三相相控励磁系统的谐波输出、提高了矿井提升机的同步电动机功率因数,使系统更稳定地运行。
Based on the analysis of the structure of the existing mine hoist excitation system, the influence of the parameters of the control system regulator on the excitation system is studied. The PWM high power factor rectifier is proposed to be used in the synchronous motor excitation system instead of the traditional thyristor excitation system to reduce the harmonic output of the original three-phase controlled excitation system and improve the power factor of the synchronous hoist motor. System more stable operation.
