提出了阿基米德波浪摆(AWS)发电场的等效建模方法,重点研究波浪力输入等效。提出基于波浪最大能量捕获控制策略下AWS波浪力输入和输出有功功率之间的稳态关系.由于等效前后的发电场输出有功功率应该相等,在规则波浪和不规则波浪2种情况下,反推获得等效模型的波浪力输入,同时计及功率补偿。搭建了波浪能发电场详细模型,并将其等效为一台AWS波浪能发电单元。仿真结果表明,单机等效模型的稳态有功输出和故障时动态响应均与详细模型高度吻合。
The equivalent modeling of wave farm based on AWS(Archimedes Wave Swing) is proposed and the equivalent input of wave force is emphatically studied. The steady-state relationship between the input and output powers of AWS wave force under the maximum energy capture control is proposed. Since the active power output of wave farm before the equivalence should be equal to that after the equivalence,the input power of the equivalent model can be derived by the inverse method in both regular and irregular wave conditions. The power compensation is also considered. A detailed wave farm model is built and simplified as an AWS-based power generation unit. The simulative results demonstrate that,the steady-state output power and the dynamic response of the equivalent model are highly identical with those of the detailed model.
