摘要
目的阐述模糊控制理论在无功补偿控制中的应用。方法系统控制策略基于模糊控制理论,以电压和无功功率的偏差为输入,经过模糊推理,以对电容器组的投入或者切除为输出。结果很好地解决了由于轻载产生投切震荡的问题。结论将模糊控制方法应用于无功补偿系统中,将专家经验与自动控制相结合,可提高补偿准确度和系统鲁棒性,从而可改善电网的供电质量。
Aim The main purpose is the application of fuzzy control theory to reactive power compensation.Methods System control strategy based on fuzzy control theory,input the deviation of voltage and reactive power according to fuzzy discursion.Then output adjusting the switching of capacitor.Results Oscillatory problem was solved successfuely due to a light-off.Conclusion Fuzzy control theory has been applied to reactive power compensation system,the expert experience was combined with automatic control,which can improve compensation accuracy and system robustness,improve quality of electricity supply grid.
