摘　　要：利用电路的基本理论,从注入功率分解的角度出发,对受控源网络的功率分布特征进行分析,得到多电源电流分量在网络任意节点和支路的功率解析表达式;每个电源的注入功率可分解为电源数个功率分量的代数和,每个分量描述2个电源间的耦合关系,电网中支路功率为具有不同分布系数的所有功率分量的代数和。同时,受控源网络的功率又表现为基础功率与附加功率之和。其中,基础功率为对称网络中相应项的功率,附加功率为与受控源的控制系数有关的功率。最后以典型受控源装置——可控串补(thyristor-controlled series compensation,TCSC)为例,用IEEE-9节点系统算例验证算法的精确性。Based on the electric circuit theory, this paper analyzed the characteristics of power distribution of the controlled source network from the aspect of power injection decomposition, and it found the multi-power source current component＇s power analytic expressions on arbitrary network nodes and branch circuits. Different power forms provided by the power source can be decomposed into the algebraic sum of different power sources＇ power components, and each component describes the coupling relationship between two power sources, and the branch circuit power in the power network is the algebraic sum of all the power components with different distribution coefficients. At the meantime, the power of the controlled source network expresses the sum of basic power and additional power. The basic power is the corresponding power in the symmetrical network, and the additional power is the power relevant to the dominant coefficient of the controlled source. At the end of the paper, thyristor-controlled series compensation （TCSC） was used for an instance, and the accuracy of the algorithm was certified by using the IEEE-9 example.
