摘要
以某风电场2 MW风力发电机组为仿真对象,对风力发电机进行结构分析,并采用模块化建模方法分别建立风速模型、风机模型、传动模型、电机模型和控制模型,给出了相应的数学模型.在南京工程学院JSCC仿真支撑系统下,用Fortran语言编写了仿真算法并建立全范围风力发电机组仿真模型.根据该风电场典型工况进行模拟计算,模拟风速从8 m/s至20 m/s变化时风电机组系统的变化动态特性,模拟结果表明所建立仿真模型能够反应实际机组的动态特性,系统能够满足风电场运行人员培训及风电系统优化等要求.
A 2 MW wind generator on a wind farm is simulated to study the structure of the generator. Modular modeling method is used to build a wind speed model, a wind turbine model, a transmission model, a generator model and a control model, together with their corresponding mathematical models. Under the aegis of JSCC simulation system of Nanjing Institute of Technology, Fortran language is used to write simulation algorithm, and then to build a simulation model of wind power generator of a whole range. The dynamitic characteristics of the system are simulated with the wind speed from 8m/s to 20 m/s in a typical condition on a wind power farm. The results of the simulation show that the simulation model can reflect the real dynamic characteristics of the wind generator and meet the demands of training staff working on a wind power farm and systemic optimization of wind power.
