摘要/Abstract

摘要： 文章为解决水平轴潮流能发电系统在低于设计流速下叶轮能量捕获效率低的问题, 运用最大功率跟踪控制理论及叶轮与变量泵传动轴力矩平衡方程, 建立了变量泵反力矩参考值模型, 设计了间接速度控制的压力反馈加转矩控制系统, 通过小范围内调节变量泵排量, 实现叶轮最大功率捕获。整个系统的性能在自动化工作室(automation studio)中进行了仿真测试, 实验样机也进行了海上试验。仿真测试和海试结果显示, 该控制系统工作稳定性好, 仿真和海试时叶轮的捕获功率系数分别在0.35和0.33附近波动, 相比不加控制, 分别增加了约0.03和0.05, 提高了叶轮的捕获效率, 验证了控制系统的有效性。

Abstract: In order to solve the problem of low energy capturing efficiency of the horizontal axis turbine in tidal current power generation system at low current speed, a variable pump counter torque reference value model was established. In this study, based on the maximum power tracking theory and the torque equilibrium equation of turbine versus variable pump, a control system with indirect speed control, pressure feedback, and torque control was designed to achieve the maximum power capture of the turbine by regulating the output of the variable pump in a small range. The performance of the designed control system was simulated by means of the Automation Studio software, and corresponding sea test was conducted. Test results showed that the control system ran steadily, the captured power coefficient of the turbine fluctuated near 0.35 and 0.33, respectively, in the simulation and sea trials; compared with the uncontrolled, these numbers increased by 0.03 and 0.05, respectively. The capture efficiency of the turbine was enhanced, and the effectiveness of the control system was verified.
