摘要
在分析潮流能发电装置特点的基础上,设计了25kW独立运行式水平轴潮流能发电系统。样机系统由经过优化设计的能量捕获机构、功率分流合流式的机械传动机构及蓄电池储能的电气控制系统组成。在系统透平机构捕能性能的理论预测、机械传动及电气系统的模型分析基础上,通过数字仿真对整机系统的工作性能进行了预测。海上试验结果显示,样机在实际海况下工作稳定,最大发电功率达到设计功率等级,验证了系统设计的有效性。该系统可作为独立发电装置向海岛地区用户提供电能。
Based on the analysis of the tidal current turbine＇ s characteristics, a 25 kW stand-alone horizontal axis tidal current turbine is designed. The prototype consists of an optimally designed energy capture device, a split-power mechanical driving unit, and an electrical control system with a battery bank. Digital simulations are conducted to predict the system＇ s working performance, based on the theoretical prediction of the turbine performance and the model analysis of the electro-mechanical system. The sea trial results show that the prototype system runs stably in the actual sea conditions and the maximum power generation reaches the designed power rating. The results clearly verify the effectiveness of the system. The prototype system can be used as a stand-alone power generation device to supply electricity for the users in island area.
