本文为瑞典乌普萨拉大学(作者:Rickard Ekström的硕士论文,共81页。

 

本硕士论文是乌普萨拉大学电力系Lysekil波浪发电项目的一部分。安装在变电站中的电力电子设备将作为波浪发电厂和电网之间的接口。本文研究了该变电站的逆变器、门极驱动、滤波器、控制系统和保护的设计。此外,还进行了广泛的市场调查,最终决定销售哪些部件,为驱动电路设计了PCB板。设计并测试了门驱动器和逆变相桥臂。SPWM控制算法已在LabVIEW中实现,并引入了直流补偿的概念。驱动电路和逆变器输出与理论及仿真结果吻合良好。

 

This Master thesis has been performed as part of the Lysekil wave power project atthe Division of Electricity, Uppsala University. Power electronics, placed in asubstation, will be required as an interface between the wave power plant and theelectrical grid. This paper investigates the design of the inverter, gate drive, filter,control system and protections to be used in this substation. Also, extensive marketresearch has been done, resulting in decisions of what components to bemerchandised. A PCB has been designed for the drive circuit. The gate drive and aninverter phase-leg have been built and tested. Control algorithms for SPWM havebeen implemented in LabVIEW, along with the concept of DC-compensation. Thedrive circuit and inverter outputs agree well with theory and simulations.
