120kW水平轴潮流能发电机组载荷计算
|
摘要
对海流能发电机组的发展状况进行了简单的介绍,以120 kW机组为例,对水平轴海流能发电机组的载荷计算方法进行了介绍。在对拟试验海域的流速数据进行了分析处理的基础上,通过Bladed软件建立了机组的仿真模型,并对机组可能遇到的设计载荷工况进行了定义并完成了各工况下的载荷计算。对载荷计算结果进行后处理,得到机组的极限载荷和疲劳载荷,用于机组关键零部件的设计、计算和选型。所提到的载荷计算方法有一定的普遍意义,但载荷工况的设计、计算结果的处理尚需要根据长期的机组运行监测数据进行修正和改进。
This paper briefly introduces the development status of tidal current turbines. Taking a 120 kW turbine as an example, the load analysis method is presented for tidal current turbines. Based on the analysis of the tidal current data in the proposed testing sea area, a simulation model of the turbine is established using the Bladed software. The designed load cases that the turbine may encounter when operating are defined, before completing the load calculation under all cases. By processing the load results, the extreme and fatigue loads are obtained,which can be applied in the design, calculation and type selection of key parts and components of the turbine.The proposed load analysis method is feasible and of a universal significance, but the definition of load cases and the processing of load results still require amendment and improvement based on long-term monitoring data of the operating turbine.
