A Novel Wireless Parallel Control Strategy for Modular APF Based on the Point of Common Coupling Harmonic Currents Distribution
摘要
Abstract
A novel wireless parallel control strategy for modular active power filters (APF) is proposed in this paper based on the harmonic current distribution at the point of common coupling (PCC). This strategy is used to overcome the defects of traditional wired control methods, such as complex communication links and control, high cost and low reliability. Moreover, it can also solve unbalanced capacity distribution among modules under the capacity limitation wireless control mode. By utilizing the current distribution information at the PCC, the fault tolerant control can be realized without communication among the modules. First, the primary principle of this novel wireless control strategy was discussed in detail. The overall technological scheme was then introduced, including current detection, synchronous control, fault recognition, fault type recognition and automatic current-balancing control. Finally, the control system of the modular APF based on this strategy was designed. Theoretical analysis and experimental results show that, with this method, both the construction and the control system of the modules are independent with each other. In other word, the modular APF has higher flexibility, security and stability.关键词
