基于DSP的低压动态无功补偿装置

The Device of The Low-Voltage Dynamic Var Compensator Based on DSP

介绍了无功补偿主电路的构成、硬件组成及算法等。该装置采用双 CPU 结构,有效地提高了其性能;可构成多主冗余系统的 CAN 总线网,同时采用 RS-485作为通信网络,以适应不同层次的应用需要;并采用先进的电容器投切方式,具有自动抄表功能。解决了动态无功补偿的难点,包括冲击电流、投切振荡、谐波放大、电容器的保护等。

This paper Introduces structure of the var compensator circuit,constitutes of the device hardware and calculation. This equipment uses two CPU to enhance its capability,adopting CAN of the real multi-master redundant system and the RS-485 in order to adapt to different application.The device has advanced throw-cut mode of the capacitor and function of automatic meter,which solvs the tickler of the Dynamic Var Compensator including lashing current,throw-cutting surge,wave concomitant,capacitor protecting,and so on.
