An improvement in a wind electric power plant of the type disclosed in U.S. Pat. No. 4,059,771. The improvement comprises including an exciter armature and an associated exciter field winding into the electric circuit disclosed in U.S. Pat. No. 4,059,771. The improved wind electric power plant is utilized to supply A.C. power to hot water heater loads and/or auxiliary loads such as air conditioners, devices to manufacture hydrogen gas and the like, wherein at least one of said auxiliary loads is solar-powered. Associated circuitry is provided so that power can be supplied alternatively to either the hot water heater loads or to the auxiliary loads. The power supplied via the associated circuitry supplements power to the at least one solar-powered auxiliary load, thereby maintaining a full load on the electric power plant to insure the quiet operation of that plant.
In a wind electric plant of the type including a wind driven propeller or the like supported at the top of a tower and connected to drive an alternator supported on the tower to generate electrical energy, and storage battery means connected to be charged by the alternator, electrical control circuit means connecting the storage battery means with the field winding of the alternator to supply a substantially constant current to the field winding at substantially all speeds of operation of the wind electric plant within a predetermined range of speeds to excite the field of the alternator and thus obtain full excitation of the alternator field at substantially all speeds of operation of the wind electric plant within said range, the improvement comprising:
