Abstract

The principle of this article is to derive a numerical model of a wind energy system (WES) with transient speed wind rotary turbine with mechanical drive, pitch angle adjustment, Permanent magnet synchronised generator (PMSG), and power switched converter. The model uses low-solidity rotors which is necessary for a WES when used for power generation. The important features of the WES model is that it is designed to have maximum value of coefficient of performance in line with Betz limit, uses power electronic based connection between the generator and the dc bus paving way for dynamic control, has a good specific rated capacity (SRC) and uses a Permanent magnet synchronous generator instead of conventional induction generator. Simulation models are presented and the output is compared with conventional WES system.

摘要

本文的原理是推导具有瞬变风速风力涡轮机的风能系统（WES）的数值模型，该风力涡轮机具有机械驱动，桨距角调节，永磁同步发电机（PMSG）和功率开关转换器。该模型使用低强度转子，当用于发电时，这是WES所必需的。WES模型的重要特征在于，它设计成具有符合贝兹极限的最大性能系数，在发电机和直流母线铺路之间采用基于功率电子的连接方式进行动态控制，具有良好的额定额定容量（SRC），并使用永磁同步发电机代替传统的感应发电机。给出了仿真模型，并将输出与常规WES系统进行了比较。
