Can a six-phase synchronous generator operate as a stand-alone energy source?
This paper presents the steady-state behavior of a SPSG (six-phase synchronous generator) configured to operate as a stand-alone electric energy source in conjunction with a hydro power plant. A purely experimental treatment is provided with the emphasis placed on operating regimes that illustrate the advantages of using SPSG.
Comparative studies performed clearly depict that the six-phase generator is able to deliver more power (increased power/weight ratio) in the same frame. Also, the speed and voltage regulation was found to be better than its three-phase counterpart.
What is a six-phase synchronous machine?
Schiferl and Ong have presented the mathematical model of a six-phase synchronous machine wherein the mutual leakage couplings between the two sets of three-phase stator windings are considered.
What are the advantages of SPSG for a three-phase synchronous generator?
A further advantage of SPSG with respect to a three-phase synchronous generator is the possibility of combining the outputs of the two three-phase windings for the supply of a single three-phase load, by means of a three-winding transformer with dual star-delta connected primary.
Can a six phase self-excited induction generator be used in stationary reference frame?
An alternate modeling approach in stationary reference frame has beensuccessfully implementedfor a six phase self-excited induction generator (6Ph-SEIG) in this paper. Various aspects related to the implementation of high-phase SEIGs as well as selection of optimum excitation capacitance are described in detail.
Finally, a consolidated six phase loadmay be supplied from a balanced six phase output. The six-phase supply is especially desirable for high power rectifiers as it will yield much better rectification efficiency compared to three-phase input power. In the present investigation six-phase loading is considered.
