| 摘 要： | 讨论了多机电力系统能控性和能观性问题,以非线性微分几何理论为工具,给出了一般仿射非线性系统的能控性和能观性的定义及其判据,然后将多机电力系统数学模型作为n维流形上的非线性系统,并将其状态看作流形上的局部坐标.对多机系统数学模型进行了适当处理,在不失一般性的前提下,以二机电力系统作为讨论对象,分析得出了相应的结论.参5.

| Abstract: | The paper discusses the contollability and observability of multimachine power systems. At first, the definition and criterion for controllability and observability of general affire nonlinear system are given by the mean of differential geometric theory. Then the mathematical model of multimachine power system is regarded as nonlinear system on n-dimension manifold and the states as local coordinate on the manifold. The model is properly dealt with generation, double-machine power system is acted as the obhect for disvussion and the corresponding conclusion is obtained by analysis. 5refs. |
