Abstract

The paper addresses the issues of electromagnetic compatibility of the thyristor voltage regulator (TVR) applied for induction motor soft start with the power network. In particular, it shows an impact of soft starters implemented on the basis of the TVR on the network voltage wave shape at their connection points. Under certain conditions, a distortion level of the regulator can exceed a maximum limit. In such cases, passive power filters (PPF) may be used to improve a voltage harmonic composition. It is shown that the PPF application improves induction motor start-up conditions; this fact should be taken into account in the PPF design. The methodology of filter parameters calculation is proposed in the paper. The simulation results are also presented, showing a significant reduction of the higher harmonics level and the motor start-up time when the passive power filter is used. It is concluded that the PPF installation in the thyristor soft starter systems of induction motors is advisable.

无源电源滤波器在感应电动机软起动器上的应用

研究了用于感应电动机软启动的可控硅稳压器(TVR)在电网中的电磁兼容性问题。特别是显示了基于TVR实现的软起动器对其连接点处网络电压波形的影响。在某些条件下，稳压器的失真水平可以超过最大限制。在这种情况下，无源电源滤波器(PPF)可用于改善电压谐波组成。结果表明，PPF的应用改善了异步电动机的启动条件;在PPF设计中应考虑到这一事实。本文提出了滤波器参数的计算方法。仿真结果表明，采用无源电源滤波器可显著降低高次谐波电平，缩短电机启动时间。结果表明，在感应电机可控硅软起动系统中安装PPF是可取的。
