Three-Phase Four-Wire STATCOM Control Method Based on Neural Network PI Controller

摘要

In this chapter, the control method of STATCOM in three-phase four-wire system was proposed. The neutral-point balance control and neural network PI controller were combined to design the neural network triple close-loop control method. Simulation result shows that the proposed control method is capable of realizing the neutral-point balancing control in three-phase four-wire STATCOM and the control precision is higher than that of the conventional control method.
