Hydrogenation is one of the oldest technologies for harnessing electricity from water. In order to control the power harvested from water, conventionally small scale hydro-power station uses a fixed speed drive with mechanical regulation. This conventional arrangement is expensive and is not affordable for small scale hydro-power plant. In this paper, an advanced configuration of a micro-hydro power plant (MHPP) is proposed, which is more efficient, lighter and smaller. The proposed design is quite simple and it eliminates the mechanical adjustment with the help of an efficient Power electronic System (PES). The designed topology consists of a five-level Transistor Clamped Multilevel Inverter (TCMLI) that allows the efficient and reliable generation of high quality electric power from the MHPP at lower costs. A detailed model of the MHPP is derived and five-level control scheme is designed. Results are verified by computer simulation.
