This paper deals with MATLAB Simulink simulation software package used for the description of operating regimes of disc generator with constant magnets for two–rotor wind turbine with counter–rotation, used in low power wind–driven power plants (WDPP). The results have shown that at high wind speeds, while maintaining a constant angular rate of windwheel (WW), the power generated by WW decreases. The developed model allows obtaining mechanical and energy characteristics for various wind speeds at given certain wind–driven power plant (WDPP) design parameters, as well as the optimum combination of the blade pitch, rotational rate, load torque and the control law that ensures highest power efficiency of wind energy utilization.

This article is devoted to investigation of electric parameters of disk generators for micro hydro station. Density of current does not follow Ohm's law, it grows proportionally to power 3\2 of applied voltage and inversely proportional to squared distance between them. This difference of laws of thermionic current from the laws of current in metals is determined by two kinds of reasons. Firstly, electrons in metals collide with positive ions which form hard layer of metals and face because of that the resistance to its motion, which is not observed in vacuum. Secondly, thermionic current means that in space between electrodes there are only free electrons, whose charge is not compensated with charges of positive ions. Quite opposite thing can be observed in metals and it results in distortion of field of so–called spatial charge by the field of electrodes.
