摘要

先进的静态无功发电机(ASVG)可以在许多方面对电力系统有益。为了评估其动态性能，在瞬态研究中应该对器件进行适当的建模。本文描述了平衡系统和不平衡系统中ASVG的动态行为。当非对称电力系统故障或对称运行导致母线电压不平衡时，负序电压分量会在ASVG交流侧产生负序三次谐波电压。提出了一种研究不平衡系统暂态稳定性的模型。

ASVG model for transient stability studies in unbalanced systems

An advanced static VAr generator (ASVG) can be beneficial to power systems in many ways. In order to evaluate its dynamic performance, the device should be modeled appropriately in transient studies. This paper describes the dynamic behavior of ASVG in balanced systems and unbalanced systems. When bus voltage becomes unbalanced due to asymmetrical power systems failure or symmetrical operation, the negative sequence voltage component will cause negative sequence and 3-order harmonic voltage on the AC side of the ASVG. A model is presented for the transient stability studies in unbalanced systems.
