Small-scale wind power in off-grid and its controlling by variable load

This article solves problem of small-scale wind power in off-grid. Article offers solution for controlling load by prototype. Prototype manages the load so that the induction generator is still in his optimum. The article focuses on controlling by prototype. The whole design of prototype, suitable value of capacitors and load is also discussed in this paper. Prototype is created from MOSFETs and microcontroller structure it allows really low price of whole prototype. The prototype is designed so that it can be used for different powers of induction generator and different weather conditions. The prototype has got self education program for learning of optimum of induction generator. Article shows waveforms from measurements, where the prototype operates in education mode and where the prototype operates in full educated mode.
