Abstract：There are a lot of reactive power and nonlinear loads in distribution network in three-phase four-wire system.It has a good effect of a low-voltage static var generator, that works under a balanced load. However, in the case of unbalanced load, the result is not so good. In this paper, a novel control method for three-level static var generator under unbalanced load in three-phase four-wire system is proposed to solve the problem. The proposed system is modeled under the Matlab/Simulink environment, simulation results show that: the strategy this paper proposed can achieve three-phase reactive-power compensation effectively in three-phase four-wire system, and has a good effect on reactive-power compensation under the unbalanced load.
