| 摘 要： | 研究变速恒频潮流能发电系统方案及其控制策略。提出一种通过寻优直流Boost变换器占空比达到对潮流能最大功率点跟踪(Maximum Power Point Tracking,MPPT)的控制算法,而不需要利用水轮机转速及其转速-功率特性。建立了并网逆变系统的数学模型,给出基于SVPWM调制的网侧控制策略。通过电流闭环控制和电网电压矢量定向控制,可进行功率因数的调整,从而实现在电网侧对有功功率和无功功率的独立控制,仿真结果表明了设计方案的正确性和可行性。

| Abstract: | This paper proposes a variable speed constant frequency tidal current generation system and its control strategy.An MPPT(Maximum Power Point Tracking) control method is presented,in which the maximum energy capture from tidal current is achieved by seeking the optimal duty cycle of boost converter without using hydro turbine characteristic at various tidal current velocity.The mathematical model of the grid-connected inverter is built,and the SVPWM(Space Vector Pulse Width Modulation) based inverter and its... |
