| Abstract | |
This PhD thesis has as its main contribution the realization of proposed power control systems for the Switched Reluctance Generator (SRG) in wind power generation. This work pioneers two proposals of drives for switched reluctance generator that depend on the operating speed. With the proposed systems it's possible to get $30\%$ more wind energy those systems with conventional generator. It is proposed to direct power control by hysteresis for operation at low speeds and direct power control by single pulse for high speeds. The power controls were first developed using proportional integral controllers and to improve system performance sliding mode controllers were used. It introduces a switching system of modes operation which enables SRG to operate in large range of speed variation. The modeling of the developed system is described in detail and dynamic simulations were carried out to verify the performance of the proposed control systems. The SRG works in self- excited mode using the common DC link bus of the frequency inverter connected to electrical low-voltage grid. This eliminates the need for additional converters and excitation sources for magnetizing of SRG. An experimental platform was developed for testing of the proposed system (AU) | |
