摘　　要：数字液压风力机可根据风速大小使相应排量液压泵参与工作,使液压风力机在整个工作风速范围内始终保持高效。由于大型风力机不具备开展实验研究的条件,且风力机中的液压系统具有较强的非线性,为了准确研究数字液压风力机多泵切换时系统工作特性的变化规律,提出了一种基于Links-RT的数字液压风力机半实物仿真系统,并对数字液压风力机风轮特性模拟和最大功率跟踪控制进行设计。通过风速阶跃变化、恒定风速时多泵切换、渐变风速多泵切换3种工况下数字液压风力机工作特性的实时仿真测试,验证了数字液压风力机半实物仿真系统的正确有效性,为数字液压风力机的稳定运行和风能高效利用提供理论依据和技术参考。The digital hydraulic wind turbine can engage the corresponding displacement hydraulic pump according to the wind speed,so that the hydraulic wind turbine can always maintain high efficiency in the whole working wind speed range.Since large wind turbines do not have the conditions to carry out experimental research and the hydraulic system in wind turbines has strong nonlinearity,a semi-physical simulation system based on Links-RT for digital hydraulic wind turbines is proposed in order to accurately study the change law of system operating characteristics when multiple pumps are switched in digital hydraulic wind turbines,and to design the simulation of wind wheel characteristics and maximum power tracking control for digital hydraulic wind turbines.Through the real-time simulation tests of the operating characteristics of the digital hydraulic wind turbine under three operating conditions of step change of wind speed,multi-pump switching at constant wind speed and multi-pump switching at gradual wind speed,the correct validity of the digital hydraulic wind turbine semi-physical simulation system is verified,which provides theoretical basis and technical reference for the stable operation and efficient utilization of the digital hydraulic wind turbine.
