Abstract: A cooling apparatus for electric equipment includes a generator configured to receive a heat load from first electric components, a evaporator configured to receive a heat load from second electric components, a closed compartment enclosing the generator and evaporator, and a absorber transferring heat from heated fluid to the outside of the closed compartment. To obtain an efficient and reliable cooling apparatus, the cooling apparatus includes a first expansion device which reduces the pressure of the fluid, and forwards the fluid in a liquid state and with a lower pressure to the secondary cooling element, which transfers heat to the received fluid from the second electric components for evaporating the fluid.

Abstract: A method for generating switching plans to restore power to out-of-service areas after fault isolation through back feeding. A chromosome architecture is defined to create chromosomes representing candidate post-restoration systems. The chromosomes are evaluated are repeatedly genetically altered until an acceptable solution is identified. The solution identifies a plurality of switching operations that back feed power to the out-of-service areas in the most optimal manner.
