A Control Device for Distribution Transformer Neutral Current and Loss

This paper develops a control device for distribution transformer neutral current and loss caused by unbalanced loads. Due to multi-objective optimization, its control strategy is designed, considering the reliable operation of distribution transformers and its performance. This device can gather power quality parameters, calculate the optimal regulation and control capacitor switching, which consists of power quality acquisition unit, central processing unit (CPU), capacitor control cabinet and power supply. After simulation and experiment, the result shows device can achieve target by dynamic adjustment.
