配电网智能动态无功补偿装置设计

针对传统配网中低压无功补偿装置响应速度慢、控制精度和速度难以保证等问题,在分析了无功补偿原理的基础上,设计了一套智能动态无功补偿装置。装置以80C196KC单片机作为核心控制器,采用设计独立的TSC脉冲触发装置,利用ULN2003AN来驱动脉冲触发装置工作,控制晶闸管的导通和关断,从而控制电容器的投入与切除。实践证明该装置具有良好的实时性和控制精度,具有一定的推广价值。

Design of the Smart Dynamic Reactive Power Compensation Device in Distribuuon Networks

The traditional reactive compensation device in distribution network has the disadvantage of slow response, low control precision and low speed. Base on the analysis of the reactive power compensation, a device of smart dynamic reactive power compensating device is designed. The device uses 80C196KC single-chip microcomputer as the core controller, adopts the independent TSC pulse triggering device that uses ULN2003AN to drive to controls thyristors conduction and off, so as to control the capacitor input and removed. The practice proved that the device has the good real-time and control accuracy, so, it has certain value of popularization.
