Enhanced power transfer capability through a sixphase converted transmission system is becoming an area of growing interest in the power system industry. However, this conversion will have an impact on the system stability. In this paper, the transient stability of a 4-bus, 2 generators test system is investigated in time domain considering conversion of threephase double-circuit to the six-phase single-circuit transmission system. The paper presents also comparisons between critical clearing times for both three and six-phase cases. All types of fault on the middle of transmission line are simulated using PSCAD/EMTDC. From the simulation results, it has been shown that the 4-bus, 2 generators test system with six-phase singlecircuit transmission has a better stability limits compare to the three-phase double-circuit transmission.

“…Single-phase and three-phase electrical systems represent the vast majority of alternating current (AC) systems, but AC installations and equipment with a different number of phases also exist. For example, two-phase power distribution is still present in some parts of Philadelphia-a remnant of the old two-phase power system [1] and pilot six-phase transmission lines are currently operated by some grid operators [2,3]. Scott transformers converting three-phase power to two-phase power are used in some traction applications and to supply special two-phase loads [4], whereas experimental transformers that convert three-phase power to either five-phase [5,6] or seven-phase power [7,8] have been built for research purposes.…”

The method of symmetrical components is an important mathematical tool for electrical engineering, as it simplifies the analysis of unbalanced electrical circuits. The method is used almost exclusively for three-phase networks, but with the advancement of multiphase electrical systems, it could be convenient to utilize it for such systems as well. In this paper, the method of symmetrical components is used to analyze a generic five-phase electrical system for various short-circuit faults and to determine the sequence networks connections for these faults. The analysis performed covers the derivation of the symmetrical components for voltage/current and of fault currents. The analytical results and the inferred sequence networks connections are validated by computer simulations. This paper therefore extends the literature on short-circuit analysis of multiphase electrical systems using the method of symmetrical components.

“…The following are examples of high phase order power systems, whose representation in power-mismatch load flow is contemplated by the equations derived in this work: six and twelve-phase transmission lines [21]- [23], double-circuit three-phase transmission lines [24], [25] and pairs of pole-sharing three-phase distribution lines [26], [27].…”

The standard power-mismatch Newton method is still frequently used for computing load flow due to its simplicity and generality. In this paper, a matrix-based generalization for the usual power flow equations to an arbitrary number of phases is derived. The proposed equations enable computing power injections and the Jacobian matrix in terms of submatrices that compose the network admittance matrix. Besides the more compact representation, another advantage of the proposed generalization is execution time reduction compared to the standard scalar formulation. Simulations are carried out to demonstrate the time reduction achieved via the proposed equations.
