摘　　要：进行电力系统稳定控制研究时，必须首先建立研究对象的数学模型。由于选取不同的电机数学模型和不同的轴系，多机电力系统的数学模型有多种不同形式。本文较详细地介绍了几种常用的多机电力系统数学模型，并着重阐明其间的差别和特点。最后对如何确定系统的稳定平衡平衡点或控制目标进行了讨论，并论述了多机电力系统观测解耦状态空间模型，据此可以通过局部测量构成局部控制器并达到全局稳定的目的。It must be firstly to establish the models of multimachine power systems for stability and controlstudies. Since various models of generators in various frames may be selected , there are various models ofmultimachine power systems. Some models of multimachine power systems,which may be frequently adopted for stability and control studies. and their characteristics and the differences among them are introducedin this paper.Then, establishing equilibrium peits or control aims for stability control of systems has beendiscussed.Finally,a observation decoupled state space model is illustrated. According to it,a local controllerfor system stability can be constructed.
