电能稳定的潮流能发电最大能量追踪系统研究

Study on MPPT and Stable Electric Control for Tidal Current Energy Conversion Systems

通过对潮流能发电系统的研究,针对能量的最大利用和电能稳定的问题,采用液压传动,通过一种新型实时最大功率点追踪(MPPT)的方法进行容积调速可以较好地实现能量的最大捕获,后续电力电子部件通过模糊自整定PID调节的脉宽调制脉冲(PWM)实现电压及频率的稳定。为了验证控制系统的准确性和有效性,建立了系统的数学模型。运用Matlab/Simulink并结合液压系统软件AMESim来完成系统的建模和仿真。

Through the study of tidal current energy generation system, for issues about achieving maximum uti- lization of energy and obtaining stable electric energy, hydraulic transmission system was adopted which used the volume control by a novel method for real-time maximum power point tracking and the voltage and frequency stabili- ty achieved by subsequent power electronic component which adopted pulse width modulation regulated by PID. In order to verify the accuracy and effectiveness of the control system, the mathematical models for the systems are es- tablished and the Matlab/Simulink combined the AMESim software was used to complete the modeling and simula- tion of system.
