A novel hybrid wind generation scheme suitable for varied speed grid isolated installations

Generation of electrical power from wind is much advantageous due to its clean nature and abundance. This paper presents a wind generation scheme which uses two wind generation sources. The first source is a permanent magnet synchronous generator (PMSG) operating in maximum power tracking mode. The other source is a single-phase dual stator winding induction generator (DWIG). The two machines are connected together with the help of rectifier and a common DC bus. The hybrid wind generation configuration thus obtained can harness wide range of wind speeds for generation purpose and can sustain single-phase isolated domestic loads. Provision of storage is kept using a suitable storage battery during surplus energy available. Additionally, photovoltaic (PV) panel can be added across the DC bus for generation and sustaining loads during no wind. The control of the two generators with PV panel is studied in the paper. The simulation results obtained, backed by the experimental findings validates the proposed concept.
