Abstract

Today, Sustainable resources are most preferable due to environment protection concern and also efficiency of the system is too high. Wind power energy is one of the most popular among these. A varying speed wind turbine coupled to a PMSG is linked to the electric network via a frequency changer (fully controlled). The frequency changer is composed of a stator side converter with appropriate controller, a DC link (capacitor) and a converter with control system. For stability consideration, many control topologies are adopted and tested under different operating conditions. However all have some merits and demerits. Dynamic performance is the basic concern for the smooth operation of the electric network. A detailed Cascaded controlled converter system where several PI controllers are used in this paper. Whale optimization technique is used on grid side inverter. Detailed modelling of this system is established here, where simulation is done using MATLAB/SIMULINK.

并网变速风力发电机级联控制变流器系统

如今，出于对环境保护的考虑，可持续资源是最可取的，而且系统的效率太高。风能是其中最受欢迎的能源之一。变速风力涡轮机连接到PMSG通过变频器连接到电网(完全控制)。该变频器由带适当控制器的定子侧变换器、直流链路(电容器)和带控制系统的变换器组成。出于稳定性考虑，采用了多种控制拓扑，并在不同的操作条件下进行了测试。然而，都有一些优点和缺点。电网的动态性能是电网平稳运行的基本问题。本文详细介绍了一种由多个PI控制器组成的级联控制变换器系统。并网侧逆变器采用鲸鱼优化技术。本文对该系统进行了详细的建模，并利用MATLAB/SIMULINK进行了仿真。
