摘要

本文提出了利用降压型DC-DC变换器占空比控制潮汐能发电系统最大功率点跟踪的新控制方法。本文提出的新型最大功率点跟踪(MPPT)控制方法的一个优点是不需要利用潮汐能机在不同潮速下的特性,不需要测量潮汐能机的潮速或/和转速进行发电。因此,该系统具有成本低、效率高、复杂度低等特点。对所提出的控制方法进行了数学分析,并利用Matlab Simulink进行了计算机仿真。并采用模糊控制器对占空比进行调节。

New control method of maximum power point tracking for tidal energy generation system
This paper proposes new control method of maximum power point tracking for the tidal energy generation system using the duty ratio control of buck type DC-DC converter. An advantage of new MPPT(Maximum Power Point Tracking) control method presented in this paper is not necessary to use the tidal turbine characteristic at various tidal speed and measure the tidal speed or/and the rotation speed of tidal turbine for generation. Therefore the resulting system has the characteristics of lower cost, higher efficiency and lower complexity. Proposed control method was analyzed mathematically and tested by computer simulation using Matlab Simulink . And the fuzzy controller was applied for regulation of duty ratio.
