FIELD: engines and pumps.
SUBSTANCE: invention relates to power generation plants built around solar batteries and electric-jet plasma engines. The proposed method comprises measuring the engine anode voltage and current, stabilising anode voltage at maximum tolerable level and stabilising anode current by varying the working medium consumption. The solar battery output exceeding the engine maximum tolerable power consumption, the working medium consumption is varied so that the anode current increases to its maximum tolerable limit and, there after, decreases till a preset level, lower than the anode current maximum tolerable level. The solar battery output decreasing to the engine maximum tolerable power consumption and lower, the working medium is varied so that the anode current increases till the anode voltage drops down by the preset amount below the maximum tolerable level and goes on decreasing till the anode voltage becomes equal to the maximum tolerable level. The proposed device incorporates a voltage converter connected to the solar battery inputs and, by its outputs, to the engine electrodes, a current and voltage transducers connected in between the said voltage converter and the engine, current and voltage comparators, their first inputs being connected to the aforesaid voltage and current transducers and their second inputs being wired to the reference voltage sources corresponding to the engine anode current and voltage maximum tolerable levels. The current comparator output is connected, via a switching circuit, to the working medium consumption amplifier-shaper input, the first output of the aforesaid voltage comparator being connected to the said working medium consumption amplifier-shaper and its second output being wired to the switching circuit.
EFFECT: higher reliability of engine anode current control and maximum power take-off from solar battery.
