Continuation three-phase power flow: a tool for voltage stability analysis of unbalanced three-phase power systems
TL;DR: In this paper, a continuation three-phase power flow (CTPFlow) approach is proposed to analyze voltage stability of unbalanced three phase power systems, which can be used to obtain the PV curves of the unbalanced power systems.
Journal ArticleDOI
Fast three phase load flow methods
TL;DR: Three-phase sequence decoupling-compensation models of unsymmetrical transmission lines are introduced, which can be used to analyze both normal and abnormal three-phase power system steady-state operation.

An efficient power flow algorithm for weakly meshed distribution systems
TL;DR: In this paper, a backward and forward sweep algorithm for the three-phase power flow analysis of weakly meshed distribution system is proposed, where the linear proportional principle is applied to find the ratios of the specified (or new) and calculated bus voltages of the decomposed real and imaginary parts of the network.

Method of Symmetrical Co-Ordinates Applied to the Solution of Polyphase Networks
TL;DR: In this article, a general discussion of unsymmetrical systems of co-planar vectors leads to the conclusion that they may be represented by symmetric systems of the same number of vectors, the number of symmetrical systems required to define the given system being equal to its degrees of freedom.

Analysis of unbalanced polyphase networks by the method of phase co-ordinates. Part 2: Fault analysis
TL;DR: A general analysis of power-system polyphase networks under fault conditions is developed in terms of the phase-co-ordinate representation, showing that the problems of multiple unbalanced faults on unbalanced systems can be analysed with no more difficulty than balanced 3-phase faults on balanced systems.

Circulating Currents in Paralleled Untransposed Multicircuit Lines: II - Methods for Estimating Current Unbalance
TL;DR: In this article, the effect of individual circuit current unbalances resulting from currents circulating between the paralleled circuits are investigated and evaluated on a present worth of annual loss basis, and the influence of series capacitor-line compensation is also shown.

Generalised polyphase fault-analysis program: calculation of cross-country fault
TL;DR: In this paper, a general computer program using the phase co-ordinate technique has been developed for analysing series, shunt and simultaneous faults on balanced and unbalanced polyphase electrical networks, eliminating the need for maintaining numerous fault analysing subroutines, one for each kind of fault, and making the solution of many difficult and previously unsolvable problems possible.
