摘　　要：对转方向和相位差对并列式双垂直轴风电机组的气动性能至关重要,决定了风电机组叶片受力特性和功率输出特性。为研究对转方向和相位差对并列式双垂直轴风电机组气动性能的影响,文章采用致动线方法(ALM)对一组并列式双垂直轴风电机组进行了三维数值模拟。首先,通过风洞试验数据验证了ALM预测出的垂直轴风电机组功率输出的准确性。继而使用验证后的数值方法对该并列式双垂直轴风电机组的气动性能进行了分析。结果表明:对转方向和相位差对并列式双垂直轴风电机组的气动性能有显著影响,如不考虑相位差,并列式双垂直轴风电机组的同向旋转布置和反向逆流旋转布置会对系统的气动性能产生负面影响,而反向顺流旋转布置会产生正面影响;考虑相位差的影响时,反向逆流旋转布置仍然被证明具有负面影响,反向顺流旋转布置对气动性能的有益效果也将得到增强,但修改相位差可以减少甚至抵消由同向旋转布置引起的功率损耗。对于所采用的两叶片双垂直轴风电机组,80°的相位差和反向顺流旋转布置是最佳配置参数,与二倍单机功率相比,该布置可以使并列式双垂直轴风电机组增加约6%的功率输出。The relative rotating direction and the starting phase difference are very important to the aerodynamic performance of the multi-vertical axis wind turbine system.To study the influence of the relative rotating direction and the start phase difference on the aerodynamic performance of the parallel twin vertical axis wind turbine system,this study uses the Actuator Line Method(ALM)to conduct a three-dimensional numerical simulation of a twin vertical axis wind turbine system.First,the accuracy of the power output and blade force of the vertical axis wind turbine predicted by the ALM method was verified through wind tunnel data.Then the verified ALM method was used to analyze the aerodynamic performance of the parallel twin vertical axis wind turbine system.The results show that the relative rotating direction and the start phase difference have a significant impact on the power performance of system.If the start phase difference is not considered,the CoR configuration and CR-A configuration will have a negative impact,and the CR-B configuration will have a positive impact on the performance of the twin turbine system;when considering the influence of the starting phase difference,the CR-A configuration is still proved to have a negative impact,and the beneficial effect of the CR-B arrangement on the power output can also be enhanced,but modifying the starting phase difference can reduce or even offset the power loss caused by the CoR configuration.For the two-blade vertical axis turbine used in this study,the 80-degree starting phase difference and CR-B configuration are the best configuration parameters.Compared with twice the power of an isolated turbine,this configuration can increase the power output of the system by about 6%.
