Ocean currents can be a clean and renewable energy. Developing ocean currents can have great significance for alleviating energy and environmental problems. Tidal current generator control system is one of the key technologies for tidal current power generation. The paper introduces the composition of the control system of tidal current generator set and the core control technology adopted. The principle of battery charge and discharge control, energy load control and automatic pitch control in the control system of tidal current generator is described in detail from two aspects of hardware circuit design and software program development. The experimental results show that the developed control system can ensure the reliable, safe and stable operation of power generation system.
