摘要
双向潮汐机组在一个涨落潮周期内要经历正反向发电、水泵、泄水等6种运行方式,因此该类机组选型的基本原则是在相同的装机规模下,能获得最大的发电量,以达到最佳的经济效益。根据统计我国已完成规划潮汐电站的站址参数,本文开发了双向潮汐机组选型优化应用软件。软件包括机组选型、特性曲线图绘制和数据管理三大模块;建立了国家863项目完成的潮汐发电模型机组数据库,根据待开发潮汐电站的具体参数,选型软件能快速提供选型结果,包括机组转速、直径等参数的选择和性能特性曲线绘制。
Bidirectional tidal turbine under rising and ebb tides has six operation modes to meet the needs of generation,pumping and sluicing in direct flow and reverse flow,and the major goal of turbine selection is to achieve the maximum power output and the greatest economic benefit with a given capacity.Considering the parameters of tidal power sites that have been planned so far,this study develops a software for optimal selection and design of the bidirectional tidal turbine.This software has three modules,namely tidal turbine selection,curve mapping,and data management,and within it a database of model tidal turbine is constructed by using the data of those tidal turbines developed through the national projects 863.With the given specific parameters of a planning tidal plant,the software can quickly produce the optimal parameters of unit speed and diameter,etc.and also a turbine characteristics curve.
