基于DSP磁阀式可控电抗器的无功综合补偿系统

电气化铁路中常采用并联电容器-电抗器组等无源设备进行无功补偿并兼作滤波。但由于负载经常处于变化之中,采用固定容量补偿方式常常不能满足要求。通过分析磁阀式可控电抗器及动态无功补偿装置工作原理,论证了磁阀式可控电抗器在电气化铁路无功补偿的优越性和可行性。通过利用DSPTMS320F2407设计出磁阀式可控电抗器的控制装置,对可控电抗器的电感进行有效、平滑地调节,从而实现动态无功补偿的目的。本控制系统具有运算速度快,执行效率高等特点。

Reactive Comprehensive Compensation System Based on DSP Magnetic Valve Controllable Reactor

In electric railway system, using passive equipment such as fixed capacity parallel capacitor group is able to compesate reactive power and filt. However,it can't adjust flexibly compensation capacity due to load in variable state frequently. Through analysis work principle and dynamic reactive compensation principle proved advantages and feasibility of magnetic valve controllable reactor in electric railway system are proved. Designing the controlled device of magnetic valve controllable reactor through using DSP TMS320F2407, thus adjust capacity of controllable reactor effectively and smoothly,which carry out the purpose of the dynamic reactive compensation.This control system has the characteristics such as rapid and high efficiency.
