摘要
新型海流能发电装置控制系统是基于MPPT理论,增加了最大功率捕获控制及直流电路稳压控制,通过数学模型模拟海流速度及发电机电磁力矩,并在Matlab/Simulink环境下进行系统的搭建和仿真研究。其结果表明在实际输出功率对最大功率的比值基本相同,该系统实现对最大功率捕获,并在直流母线后端电压基本稳定,验证控制系统设计的有效性。通过搭建试验平台,对该发电系统进行试验研究。记录数据拟合曲线与理论公式曲线一致,且实现电压也在合理的波动范围,试验结果证明该控制系统正确,可进一步示范应用。
Based on the MPPT theory for the new control system in the marine current power generation device,this paper has strengthened the maximum power capture control and voltage-stabilizing control in a DC circuit.Using the mathematical model,this paper simulates the current velocity and the electromagnetic torque of the generator,and conducts research and building of the system in the Matlab/Simulink environment.The results show that the ratio between actual output power and maximum power is basically the same,the system has achieved maximum power capture,and the DC bus back-end voltage is basically stable,which verifies the effectiveness of the control system design.Through the construction of the testing platform,the power generation system has gone through experimental research.The data fitting curve is consistent with the theoretical formula curve,and the voltage is also within reasonable fluctuation range.The testing results prove that the control system is correct and can be further applied.
