Abstract

A permanent magnet generator (PM) control scheme and electrical system configuration for Wave Dragon MW wave energy power take off system is presented in this paper. The characteristics of low pressure hydro turbine are introduced first. To achieve the maximum energy conversion efficiency, a variable speed control scheme of low-head hydro-turbine using IGBT AC/DC converter is described. The electrical system configuration, operation and grid connection issues are also discussed. Voltage source PWM inverters are employed to control the output power to utility grid. Simulation model has been built, and the control of tracking maximum turbine efficiency is simulated.
