We designed a new solar-powered electromechanical drive: the photovoltaic transistor inverter-fed switched reluctance motor. A photovoltaic transistor is a conventional photovoltaic cell used as a light-controlled transistor. To obtain a motor drive, a set of photovoltaic transistors switch the current in the motor phases from an external DC power source. The switching is achieved by controlling the...
A photovoltaic switched reluctance motor converts light energy into mechanical energy, without power electronics, brushes or magnets. With the rapid decrease of photovoltaic cells price, its simplicity makes it ideal for low cost, autonomous and reliable applications, such as water pumping in isolated areas with good solar irradiation. But the concept does not allow for motion control or variable-speed...
Wind power generation facilities have been installed in the world. Recently offshore wind energy attracts greater attention, and development of wind turbine generators of higher power rating becomes more important. Superconducting technologies is expected to be applied to over 10 MW class generators. We have studied 10 MW class large wind turbine generators using superconducting technologies. The...
The recent technological trend for offshore wind power generation is toward multi-MW direct-drive units. Because conventional direct-drive generators tend to be large and heavy, high power density superconducting synchronous machines have been proposed. However such machines have unique requirements that must be satisfied for their correct operation and optimal grid integration. This paper investigates...
For the dynamic simulation of rotating electrical machines, the phase-domain model brings many advantages in terms of accuracy, efficiency and flexibility. In particular, it allows one to naturally take into account space harmonics and saturation. We discuss here the implementation of the phase-domain model with lookup tables for both the linear and nonlinear cases. First, we compare various implementations...
