This article deals with the methodological aspects of the modelling and field analysis of machines with surface mounted permanent magnets on the rotor, taking into account the anisotropic properties of the stator core. These considerations are intended to show the effect of anisotropy on the structure of the mathematical model of the machine and answer the question of whether if based on classical modelling, it is possible to take into account the rotational magnetization phenomena. The results explain the question, how the magnetic anisotropy effect at rotational magnetization is important from an exploitation point of view.

Prototype set for higher efficiency of energetic potential exploitation in SHP

Full efficiency of energy conversion in small hydropower plants (SHP) can be achieved for power technology with generators working at a variable speed. This paper presents a concept of a energy conversion system dedicated for application in a prototype SHP which is based on a permanent magnet (PM) generators with a propeller turbine integrated with the generator rotors. These PM generators can work at a variable speed and therefore energy produced by the PM generators have to be converted by means of a power electronic unit to fit to the three-phase power grid parameters. The elements of such SHP like PM generator and power electronic unit are described in details.

Management of energy conversion in small hydropower plant with variable speed generators

100%
Borkowski D., Węgiel T.
|
PL
This paper presents the rules of management of an energy conversion system in a small hydropower plant (SHP). The SHP contains two permanent magnet (PM) generators which can work at a variable speed. In the article the way of obtaining the optimal work characteristic curve is described. To achieve the best efficiency the special methodology of units cooperation is also presented. The theoretic analysis is algorithmizated, implemented and tested in the real object of 150 kW electrical power. The measurement results of this object are presented.
