Power Quality Expansion for Grid Connected Wind Power System using Permanent Magnet Synchronous Generator and Trans-Z Source Inverter
Authors: ,
Abstract: This paper presents the expansion of power quality for variable speed Wind Power System (WPS) using Permanent Magnet Synchronous Generator (PMSG) and Trans Z-Source Inverter. The PMSG is having compact collection and dimensions, compare to Induction Generator. Induction Generator needs the grid power, then only start the power production. But without take up the grid power PMSG should produce the power. The impedance-source (Z-source) inverters idea to the Transformer-based Z-Source Inverter (Trans-ZSI) is implemented. The unique Z-Source Inverter (ZSI) employs an impedance network of two inductors and two capacitors coupled in an exceptional preparation to accessing the dc source. In the proposed Fuzzy Logic Controller (FLC) based trans-Z-Source Inverters, the entire impedance networks structure consists of a two transformers and capacitor. While maintaining the major quality of the earlier accessible Z-source network, the new networks demonstrate some unique compensation, such as the enlarged voltage gain, compact voltage stress, privileged inversion capability and very less harmonics content.
