Generalized Newton-Raphson and Generalized fast decoupled power flow methods are presented in this paper. There are four variables at a bus, P,Q,V,0. In common power flow calculation, two of the bus variables are control variables, and there are only three types of buses, that is, PQ bus, PV bus and slack bus. But in generalized power flow calculation, control variables of a bus can be any combinations of the four bus variables P>Q>V,θ, so the types of buses...

Generalized Newton-Raphson and Generalized fast decoupled power flow methods are presented in this paper. There are four variables at a bus, P,Q,V,0. In common power flow calculation, two of the bus variables are control variables, and there are only three types of buses, that is, PQ bus, PV bus and slack bus. But in generalized power flow calculation, control variables of a bus can be any combinations of the four bus variables P>Q>V,θ, so the types of buses are generalized, the number of possible combinations of the four bus variables is fifteen, and a bus at which none of the tour bus variables is control variable is also a type of bus, so the total number of bus types is sixteen. And in generalized power flow calculation, real and/or reactive power flows of-transmission lines can be set to be control variables, that is, real and/or reactive power flows of some lines can be specified, and the specified line real and/or reactive power flows are used as power flow equilibrium equations. Generalized Newton-Raphson and generalized fast decoupled power flow methods are developed upon the above principles. The solvability of generalized power flow calculation is also studied. Numerical results on IEEE 14-bus and IEEE 30-bus systems are given.

On basis of constant voltage model, this paper looks into a two machine four bus power system from system parameters, directions of power flow and net structure separately in order to explore relation conditions between steady voltage stability and steady angle stability in which isolation effect and nonsymmetrical effect play an important role. With the help of the results, incident in Tokyo is explained well.

以电力系统的发电机恒电势模型为基础,分别从系统的参数、功率的流向及网络的拓扑等几个方面具体考察了一个典型系统,从中揭示静态电压稳定和静态功角稳定的关联性条件,指出系统的隔离效应和不对称效应将极大地影响这两种稳定性的关系,并用此结果,成功地解释了在东京电压崩溃事故中,功角一直保持稳定的原因
