For determining the unsymmetrical three-phase load flow, two methods based on symmetrical component theory-implicit Z-Bus Method and Decoupling-Compensation Method are proposed in this paper. By utilizing the sequence reference frame, such as those of generators and transformers, the Z-Bus method can obviously increase the speed of three-phase load flow computation without losing its accuracy. By further utilizing the weak coupling feature of unsymmetrical transmission line model in positive - negative- zero sequence reference frame, the decoupling-compensation method breaks the three-phase coupled model into three sequence-decoupled models with the injection of certain compensation currents into both terminal buses of the line, thus opens up a way to the utilization of parallel processing. The validity of these methods is verified by numerical examples.

Based on the compensation of weak couplings between different sequences of unsymmetrical three-phase transmission lines in symmetrical-component reference frames, a three-sequence hybrid decoupling-compensation transmission line model is established. Based on this model, two methods——Newton-Raphson type and P-Q decoupled type for three-phase load flow study are protosed. The convergence characteristics and the computstion speed of the later is carefully analyzed. Owing to their high speed ,good convergence chartacteristics as well as suitability for parallel processing, they are promisign for analyzing three-phase large-scale power system operations.
