Design of New Power Control System for Marine Current Energy

Abstract

Based on MPPT theory for the new marine current power generation device control system, this paper has increased the maximum power capture control and voltage-stabilizing control in a DC circuit. Using the mathematical model simulates the current velocity and the electromagnetic torque of the generator, and simulates in Matlab / Simulink environment. The result shows that the ratio between actual output power and maximum power is basically the same, then the system has achieved the maximum power capture, and the DC bus back-end voltage is basically stable, which verifies the effectiveness of control system design. The construction of the test platform allowed the power generation system for experimental research. The data fitting curve is consistent with the theoretical formula curve, and the voltage is also reasonable fluctuation range. The test result proves that the control system is correct and can be further applied.
