METHOD OF AND APPARATUS FOR PRODUCING UNINTERRUPTIBLE POWER

摘要

Uninterruptible power is supplied to a load connected to a power line by connecting the power line to a rotatable member that includes a Rankine cycle turbine (57) coupled to a device that operates as a motor (52) when line power is operative to rotate the member to generate and store kinetic energy, and that operates as a generator when the line power is inoperative and the member is rotated by the application of vaporized working fluid to the turbine. The apparatus controls the working fluid appropriately depending on different operating modes of the apparatus in response to the lost of line power.
