WAVE ENERGY POWER TAKE OFF SYSTEM CONTROL AND SIMULATION

摘要

A wave energy power take off system control and simulation scheme is presented in this paper. The characteristics of low pressure hydro turbine are described. To achieve maximum efficiency, a variable speed control scheme using IGBT AC/DC converter for low-head hydro-turbine is described. The electrical system configuration, operation and grid connection issues are also discussed. Simulation model to investigate long electro-mechanical process is developed for simulating the generator-turbine starting-stop process. Effects of the water head on the torque, speed and output power are simulated. Simulation results are presented and discussed.
