近海可再生能源综合发电系统模型对比

介绍融合近海风力发电、波浪能发电以及潮流能发电的近海可再生能源综合发电系统的电气拓扑结构,并以此系统为例,在Matlab/Simulink平台下分别搭建了其详细模型和相量模型。在定性分析2种模型的区别之后,分别在风速变化时以及电网扰动故障下,对详细模型和相量模型进行了仿真对比。时域仿真结果显示,详细模型和相量模型的稳态、动态响应趋势均基本一致;详细模型仿真计算耗时长,且仿真曲线中包含高频分量;相量模型仿真计算耗时短,仿真曲线相对平滑。

Comparison of models of hybrid offshore renewable energy generation system

The electric topological structure of a hybrid offshore renewable energy generation system, including offshore wind, wave, and tidal power generations, is described. Using this system as an example, a detailed model and phasor model based on the Matlab/Simulink platform were built. On the basis of a qualitative analysis of the differences in these two models, simulations were carried out with different wind speeds and power grid disturbance faults. Time domain simulation results show that the tendency of steady and dynamic responses of the detailed model and phasor model are similar; the simulation time is longer when using the detailed model, and the simulation curves contain high frequency components; and, with the phasor model, the simulation time is shorter, and the simulation curves are relatively smooth.
