| This article presents essential methods of securing the improvement of electrical machine's operation parameters, during machine's operation in the systems with photovoltaic generator (directly converting sunlight radiation energy into electrical energy) as the basic energy source. The article mainly fixes attention on the aspects that are possible to carry into effect at the stage of project, installation and exploitation of the photovoltaic system. These aspects refer to attaining maximum efficiency of energy conversion by the machine and in the whole system, maximization of machine's lifetime, and also maximization of supply reliability of electrical machine's load. The described problem is very significant for stand-alone system structures (i.e. not co-operating with electroenergetical grid) and simultaneously without electrochemical accumulators as buffer energy sources. Such structures have: systems with direct connection of electrical machine to photovoltaic generator, systems without any electrical buffer energy source but comprising energoelectronical converter between photovoltaic generator and machine, and finally systems with two converters and a capacitor as electrical buffer source. |
