Intelligent Control and Application of All-Function Active Power Filter

An all-function active power filter which can compensate harmonics inter-harmonics, asymmetries, fundamental sequence reactive powers and so on is introduced in this paper. Its basic concept and main features working process are illuminated briefly. To solve the difficulty problem of control for all-function active power filter, its intelligent control strategy and working process based on BP neural network are expounded. First, basic theory of BP neural network to control all-function active power is analyzed. Then, the basic configuration and working process of an all-function active power filter based on BP neural network control strategy is detailed. Finally, simulations and simulative results are given. Theory analysis and the simulative results show that the intelligent control strategy based on BP neural network can make all-function active power filter in possession of full function and predominant working characteristics.
