基于四重化主电路结构的先进静止无功补偿器

Advanced Static Var Generator(ASVG) Based on four-Multiple Technique

本文在介绍ASVG的基本工作原理和基本电路结构的基础上,搭建了四重化的ASVG主电路结构,并且对该主电路从电路结构及仿真模型两方面进行了研究和分析。结果表明该主电路不仅能够大幅度提高装置的容量,且其谐波含量少,能够实现对电网进行实时的大容量的无功补偿。

The elementary structure and operational principle of ASVG are introduced. Based on them, this thesis constructs a four-multiple structure of the main circuit for ASVG. And analysis the main circuit structure from two aspects: the circuit structure and the emulation model. The result is that the main circuit can not only greatly increased the capacity of devices, but also contains less harmonic and can be able to achieve high-capacity and real-time reactive power compensation. At the same time this thesis established a mathematical model. It can be able to achieve large-capacity and real-time reactive power compensation.
