Harmonic Research Of The Active Distribution Network With Power Electronic Devices

By analyzing harmonic sources, hazards of harmonic and suppression method of harmonic of the active distribution network, we know the main source of harmonic are power electronic devices, so in order to study the harmonic characteristics of active distribution network with power electronic devices, First to establish the simulation models of a distribution network without power electronic device, and the simulation models of three-phase Inverter (AC side of the ideal voltage source) with a detailed model of control strategy based on SVPWM,and its harmonics. When access to a single inverter to distribution networks, then we study the impact of harmonics on the distribution network:First, the distribution network of high-order harmonic impact; second, low-order harmonics of the distribution network. With these two aspects of research, we a better understanding of harmonic characteristics of the active distribution network with power electronics devices.
