| 摘 要： | 大型风电场的建模分析是研究风电参与电力系统频率调控的前提。风电场内机组众多且运行方式各异,根据风电机组的整体结构及虚拟惯量控制策略的基本原理,在直驱式风电机组单机详细模型的基础上进行简化,然后按典型风速将风电场内全部机组分为三群,同群机组采用聚合方法得到等值机组,从而形成最终的风电场多机并网等值模型。考虑风速扰动和负荷扰动两种情况,通过Matlab/Simulink软件对比校验所建模型,仿真结果显示了该建模方法的有效性。

An Equivalent Modeling Method of A Wind Power Station for Virtual Inertia Optimal Control Research |
| |
| Abstract: | The model and analysis of a large wind power station are prerequisites of studying wind power participating in system frequency adjustment. There are numerous units in wind power station and they differ in operation modes, detailed model of single D-PMSG is simplified according to the structure of wind turbine and the principle of virtual inertia control, then all the units in wind farm are divided into three groups on the basis of wind speed, units in same groups aggregate into equivalent units, which parallel to form the final wind farm multi-units equivalent model. Considering two disturbances of wind speed and electrical load, we compare to verify the built model using Matlab/Simulink, the simulation results indicate the effectiveness of this modeling method. |
