| 摘 要： | 分析和建立了兆瓦级风力发电机组各部分机理模型以及有效风速的模型,针对变速恒频风力发电机组(VSCF)在低风速最大风能捕获和高风速额定功率保持的控制目标,提出了间接控制策略(ISC)和模糊滑模控制方案,并对一个实际系统在各种风况下进行仿真实验。仿真结果验证了系统控制策略的可行性,该变速变桨距风力发电系统在全风速下均能获得最佳功率,并且系统具有优良的鲁棒性。

| Abstract: | This paper analyzed and established the megawatt level wind power generation model for its each part as well as the effective wind speed model.For the goal of maximum wind power extract under rated speed wind and maintaining the power rating above rated speed wind,this paper proposed the indirect speed control strategy(ISC) and the fuzzy-sliding-model control strategy.Then an actual system was modeled and simulated with all kind of wind situation.The simulation result has confirmed that the control strategy is feasible,and this Variable Speed Constant Frequency wind turbine is able to obtain the best power curve under the entire range wind circumstance,and the system has the fine robustness also. |
