摘　　要：本文运用带负载变压器分接头转换器 (OL TC)的非线性动态关系 ,用阻抗性负载及退耦的无功—电压关系 ,对M重 OL TC网络模型的电压稳定域作了分析 ,通过合并多维矩形域的方法形成分接头的动作范围。最后对 2 OLTC系统的稳定域的形成作了较详细地分析。As to power system voltage stability,this paper uses a nonlinear dynamic model of on-load tapchanges(OLTC),impedance loads,decoupled reactive power-voltage relation to analyze simple power system model and M-bus OLTC power network model.And by forming the union of HYPERBOX method,the paper illustrates the construction of voltage stability regions in general systems.This paper also analyzes the simplified example of 2OLTC general systems detailedly.The paper comprises six sections:introduction,an analysis of voltage collapse in simple power system,dynamic network model-M OLTC case,dynamic analysis of M OLTC case,an illustration of construction of stability region and conclusion.
