ABSTRACT:
An improvement in a wind electric generation system of the type disclosed in Jacobs et al. U.S. Pat. Nos. 4,059,771, 4,228,361, and 4,228,362, with particular reference to U.S. Pat. No. 4,228,361. The improvement provides circuitry means for monitoring, controlling, regulating and indicating the complete operation of a wind electric generation plant for the advantageous purposes of: more accurately controlling, via the use of digital logic load detection and control circuitry, the selective switching and automatic diversion of the supply of alternator output energy to and from the loads of a wind electric system; supplying power to a fixed auxiliary load for a controlled programmable period of time; reducing the switching transients of load switching silicon controlled rectifier (SCR) devices; controlling and regulating, with digital logic circuit means, the excitation field current level of a wind-driven alternator during all operations of a wind electric system in which an advantageous and proficient manner as to prevent damage to various included components and structural parts thereof at times of varying favorable and/or adverse weather conditions and during times of load switching; and, supplying to a storage battery means of a wind electric plant a trickle-charge whenever it is fully charged and no alternator output is being supplied to any auxiliary loads in order to keep the individual battery cells of a storage battery means evenly charged.
