FIELD: electrical engineering. SUBSTANCE: device has prime mover whose output shaft rotates at speed S that determines certain output-power function with slope ratio Md, equal to output power-to-S ratio for each value of S and generator that produces power depending on its shaft speed; generator impedance is chosen to comply with loading capacity of prime mover drive throughout its entire speed range so that its slope ratio Mg, equal to output power-to-S ratio is approximately equal to slope ratio Md in order to provide for controlling S to maximize device efficiency. EFFECT: enhanced efficiency and minimized surges. 17 cl, 5 dwg |
