Implementation of Control System for Hydrokinetic Energy Converter

Figure 3

Schematic illustration of the control system. The turbine and generator have a common shaft. The three phases of the generator can be connected to different parts of the control system. (a) shows startup (right to left) where a DC source feeds an inverter which is controlled to start the machine, (b) is the regular controlled load, (c) is an emergency brake, and (d) is the parking brake.
