改进节点法及其方程建立的研究

以网络的独立节点电压、流控电源的控制电流及理想电压源支路的电流为网络变量,建立了线性含源网络具有理想电压源支路时的改进节点法方程。分别考虑了四种受控源的不同作用,对支路适当处理,避免了逆矩阵的运算;提出流控电源与电流变量间的两个关联矩阵B]和C],并用例子对文中提出的概念和方法作了说明。

Modified Nodal Approch and Its Equations

The modified nodal equations of the linear active network with the ideal voltage source branchs are established. The nodal voltage, controlling current of the current-controlled sources and current of the ideal voltage source branehs are used in the nodal equations. The author considers different contribution of four controlled sources and makes some appropriate treatment for the branchs and puts forward two incident matrixes: B] and C] between current-controlled sources and controlling currents. An example is given to illustrate the concepts and proposed approach.
