【电力电子】【2011】一种用于家用光伏的单相无功控制并网DC

本文为加拿大多伦多大学（作者：Xiangdong Zong）的硕士论文，共88页。

本应用科学硕士论文提出了一种单相无功功率控制的直流/交流并网逆变器，应用于家用光伏发电。逆变器利用电压源逆变器（VSI）配置，允许本地居民光伏发电积极地向公用电网提供无功功率。提出了一种低复杂度的电网同步方法，以高计算效率的方式生成电网电压的并行和正交分量，以创建与当前控制回路同步的电流参考。此外，通过在电压控制回路上使用陷波滤波器，逆变器能够在直流链路上使用小的长寿命薄膜电容器。在PSCAD/EMTDC平台上进行了仿真，并在实验室开发了样机，验证了控制器和电网同步方法的有效性。

This Master of Applied Science thesispresents a single phase grid connected DC/AC inverter with reactive power (VAR)control for residential photovoltaic (PV) applications. The inverter, utilizingthe voltage sourced inverter (VSI) configuration, allows the local residentialPV generation to actively supply reactive power to the utility grid. A lowcomplexity grid synchronization method was introduced to generate the paralleland orthogonal components of the grid voltage in a highly computationallyefficient manner in order to create a synchronized current reference to thecurrent control loop. In addition, the inverter is able to use a small longlife film type capacitor on the DC-link by utilizing a notch filter on thevoltage control loop. Simulations were performed on PSCAD/EMTDC platform and aprototype was also developed in the lab to prove the effectiveness of thecontrollers and the grid synchronization method.
