Synchronous inversion - Concept and application
Abstract
Synchronous inversion involves the use of intermittent and/or variable power sources (wind, solar electric, solar thermal, hydro, tidal, wave, ocean thermal, industrial waste heat, etc.) to supplement a primary power source (anything from a 10 kilowatt diesel/generator set to a coast to coast utility grid). The requirements of the primary power source are that it be of greater capacity and lower impedance, so that it has the ability to dictate voltage and frequency and that it be present any time the alternate power source is in use. Synchronous inversion uses an ac power network as a 'storage' medium for any form of energy that can be converted to dc power, and at the same time takes advantage of the ac power source to establish both the voltage and frequency of the converted power. This paper examines synchronous inversion from the points of view of theory of operation, metering, system design and interfacing.
