摘要
提出了STATCOM用于维持接入点电压的控制策略,并设计出了相应的变结构神经网络模糊控制器,给出了控制器的DSP实现方案。开发出了采用变结构神经网络模糊控制的基于PWM控制方式的±300kvarSTATCOM实验装置。为了验证STATCOM装置维持接入点电压的性能,论文给出了装置在冲击性无功负荷和电网电压不平衡情况下的实验结果,实验结果证明了STATCOM实验装置维持接入点电压控制策略的可行性和正确性。
The control strategy of STATCOM used for maintaining the line voltage is presented in this paper. On the basis of this strategy a variable structure neural network fuzzy controller is designed. A ±300kvar prototype PWM STATCOM under variable structure neural network fuzzy control is developed. The hardware and software of control system of STATCOM is introduced in detail. In order to confirm the voltage support effect of STATCOM under load disturbance, the experimental results are given. The experimental results show that the STATCOM can provide considerable voltage support when load disturbance occurs.
