ASVG的理论分析与仿真研究

THEORETICAL ANALYSIS AND SIMULATION OF ASVG

对于采用ＧＴＯ器件和电压型逆变器构成的新型静止补偿器（ＡＳＶＧ）的稳态工作原理及波型进行了理论分析，导出了ＡＳＶＧ各部分波型的解析表达式。计算机仿真结果表明理论分析是正确的，同时表明ＡＳＶＧ可以在省去常规ＳＶＳ大电感、大电容的条件下，具有良好的发出容性或感性无功功率的性能。

Theoretical analysis and steady-stote operating of the advanced static var generator(ASVG)using GTO thyristors and voltage-sourced inverters are presented. Analytical representations ofthe wave forms at various parts of the ASVG are derived,Computer simulations indicate the correctness oftheoretical analysis. Good performance of reactive power generation can be acheived without large banks ofcapacitors and reactors used in the conventional static var generators.
