摘要
针对水平轴潮流发电装置的变桨启动问题,建立基于叶素-动量理论的动力特性仿真模型,利用小比例模型试验对仿真模型进行检验;在此基础上,对水平轴潮流发电装置的启动特性进行研究,梳理启动阶段变桨控制的关键技术参量及其影响。研究结果表明:初始桨距角和变桨速度是影响水平轴潮流发电装置启动性能的关键因素,合理设置2个参量,能有效改善装置的启动性能。
A study of the pitch control on starting up of horizontal axis tidal current power generation device was carried out. Based on the blade elements momentum theory,a dynamics simulation model is established,which was verified by use of small scale model test in towing tank. Then the startup characteristics of horizontal axis tidal turbine was studied,and the main factors affecting startup were analyzed. The results showed that the initial pitch angle and pitch velocity are the key factors affecting the start-up performance of horizontal axis tidal turbine,and the startup performance of the device can be effectively improved by reasonably setting these 2 parameters.
