Design and Implementation of ARM-Based Reactive Power Compensation Controller With Time-Varying Limits
摘要
Abstract
An advanced RISC machine (ARM) based reactive power compensation controller with time-varying constraints is designed. The data communication between the compensation controller and SCADA is implemented by network controller chip DM9000A to substitute for traditional A/D signal acquisition. In the proposed control algorithm, the transformer taps and maximum action times of capacitor switchers are taken as constraints. According to voltage fluctuation levels in different time intervals compensation intervals of power network in one day are divided by fractal and clustering algorithm. Optimal nodal voltage and optimal reactive power are calculated by optimal power flow algorithm. The upper and lower limits of voltage and power in each time interval are calculated according to the voltage changing steps of transformer taps and the capacity of the capacitors. Thus a nine-zone diagram criterion is attained, to determine the location of the working point according to real-time voltage and reactive power of power network. The action times of transformer taps and capacitor switchers are judged by ARM to adopting corresponding compensation scheme. Actual operational data show that using the designed compensation controller the action times of both transformer taps and capacitor switchers are reduced, so the service life of both transformer taps and capacitor banks can be prolonged.关键词
