Power Quality Improvement of Unbalanced Power System with Distributed Generation Units

摘要：

This paper presents a power electronic system for improving the power quality of the unbalanced distributed generation units in three-phase four-wire system.In the system,small renewable power generation units,such as small PV generator,small wind turbines may be configured as single phase generation units.The random nature of renewable power sources may result in significant unbalance in the power network and affect the power quality.An electronic converter system is proposed to correct the system unbalance and harmonics so as to deal with the power quality problems.The operation and control of the converter are described.Simulation results have demonstrated that the system can effectively correct the unbalance and enhance the system power quality.
