摘要: |
风电场动态等值模型需要与风电场动态详细模型进行比较,以评估其等值效果。RT-LAB仿真平台具有强大的计算能力,能保证大规模风电场模型的仿真计算。在RT-LAB仿真平台上建立了包含48台2 MW双馈机组的风电场动态详细模型,研究了双馈机组空载并网前后控制策略、电机模型及其切换。对风电场按最大功率跟踪控制发电和按调度指令发电以及机组并网、解列的工况进行了仿真分析。结果表明该模型能较好地反映风电场动态特性,对风电场动态等值模型的评估以及风电场控制器的开发具有重要意义。 |

Abstract: |
Wind farm dynamic equivalent model should be compared with its detailed model for effect evaluation. RT-LAB simulation platform with powerful computing capability can ensure simulation of large-scale wind farm. A dynamic detailed wind farm model consisting of 48 units of 2 MW doubly-fed induction generators (DFIG) is established on the platform. The motor models and control strategies for idle load grid-connection are studied. Wind farm operating scenarios such as maximum power point tracking (MPPT), power dispatching, grid-connection and cutting-off are simulated. The results show that the model can reflect the dynamic characteristics of the wind farm. It is useful for the evaluation of dynamic equivalent model and the development of wind farm controllers. |
