在含受控源网络中,应用代文宁定理时,如果受控源分布在变换部分,而控制量分布在非变换部分,则是一种难于处理的情况。国内外一些知名著作对此甚至作出不能应用代文宁定理的结论。本文分析了这一情况,并提出了一种扩展的开路电压短路电流法。此法既有效地解决了这一问题,又具有一般开路电压短路电流法简便易行的特点,有一定实用性。 In the controllable source network, if the controlled source is distributed in the transform part and the control variable is distributed in the non-transform part, it is a difficult case to deal with the dyad-Manning theorem. Some well-known domestic and foreign writings even made the conclusion that they can not apply the Dai-Wen-Ning theorem. This article analyzes this situation and proposes an extended open-circuit voltage short-circuit current method. This method not only effectively solve this problem, but also has the general open-circuit voltage short-circuit current method is simple and practical, there is a certain practicality.
