摘要

本文介绍并分析了通过5级和11级电压源逆变器STATCOM控制母线电压的方法。性能分析基于电压支持水平、谐波和逆变器在将母线电压限制在可接受范围内的直流链路电压平衡程度，而性能比较则涉及成本和效率。并尝试从第一原理出发描述VSI-STATCOM的基本概念。由于更快的响应和更大的电压支持，11级在控制总线电压方面的优势也被记录下来。在此基础上对各种开关方法进行了数学描述，并对逆变器的优缺点进行了实验论证

Bus Voltage Control Through 5 and 11 Level Voltage-Sourced Inverter Statcom

This paper describes and analyses methods of controlling bus voltage through 5 and 11 level voltage-sourced inverter STATCOM. The performance analysis is based on the level of voltage support, harmonics, and degree of dc-link voltage balancing of the inverter in constraining the bus voltage within acceptable limits, whereas the performance comparison relates cost and efficiency. An attempt is also made to describe the basic concept of VSI-STATCOM from the first principle. Superiority of the 11 level in controlling the bus voltage due to a faster response and greater voltage support is also documented. Furthermore the paper describes the switching methods mathematically and demonstrates the merits and drawbacks of inverters experimentally
