Some high-torque electric machines, such as lowspeed wind generators, may be very difficult to test on load because of the large and expensive mechanical equipment required to load them (motors) or to drive them (generators). In this paper, a full-load regenerative testing methodology is described which does not require any rotating equipment to be coupled to the machine where the rated active power flows in a closed loop between the machine and a suitably connected dual-stage converter. The successful application of this methodology to a 780-kW 14-r/min wind generator prototype is addressed as a study case. Relevant experimental results are reported in a companion paper.

“…The concept was successfully applied to permanent magnet (PM) machines, with the validity demonstrated on a six-phase [5] and a nine-phase machine [6], [7]. The approach was further found to be very useful in devising regenerative testing methods for machines with multiple three-phase windings, as detailed for twelve-and six-phase PM machines in [8], [9] and [10], respectively. The concept was also tested on multiphase induction machines (IMs).…”

This paper introduces a method which can accurately transfer active and reactive power between sets of three-phase windings of a multiphase induction machine (IM). The machine has to have a multiple of three phases (3, 6, 9 etc.), with each three phases representing one set. The paper demonstrates first that the sets do not share the power in the same way as they share a torque. Therefore, the paper proposes a method that is capable of achieving accurate power sharing. This is ensured by considering the whole power that is transferred through the air-gap to/from a set, instead of considering only a power that is transferred between that set and a rotor shaft. A complete control algorithm of the proposed method is given. Experiments and simulations verify theoretical considerations and the proposed control.Index Terms--Bidirectional power flow, induction motors, inductive power transfer, microgrids, active power control, reactive power control, smart grids, wind power generation.

Substantial amount of research and development have been conducted in relation to multiple three-phase winding machines. This is due to their reliability and fault tolerant capabilities. Development of these machines requires a few tests in order to validate machine's design and characteristics. The fullload test is one of the most important tests. During this test the machine's efficiency and thermal design can be evaluated under various conditions. In this paper, a new approach of conducting the full-load test of nine-phase machine is presented. The main advantage of the proposed scheme is that there is no need for mechanical coupling of the tested machine with another one. Usually, the machine is coupled with another machine, of the same or higher power rating, which is used as a load. The proposed test utilises indirect rotor field-oriented control (IRFOC) and vector space decomposition (VSD) to achieve the desired loading and hence temperature-rise in the machine. The ability to recirculate the power among the winding sets of the nine-phase machine is an advantage of the proposed scheme. In other words, the machine is loaded using its own winding sets -hence the test is classified as synthetic loading. The proposed scheme is validated through simulation results.
