摘要
首先分析平衡系统中 Ａ Ｓ Ｖ Ｇ 的动态行为，不平衡系统中连接线上正序电流、负序电流对直流侧电容电压的影响，得出系统不平衡情况下 Ａ Ｓ Ｖ Ｇ 交流侧有负序电压和三次谐波电压分量的结论。并在此基础上提出了适用于系统不平衡情况 Ａ Ｓ Ｖ Ｇ 暂态稳定计算用模型。仿真结果验证了模型的正确性。
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 AC side of the ASVG.A model is presented for the transient stability studies in unbalanced systems.Finally the conclusion is verified by the followed simulation results.
