Abstract: Oscillation mitigation circuits are implemented in a system for supplying electric power to load circuit boards, for example, load circuit boards entirely immersed into a bath of dielectric heat transfer fluid. The oscillation mitigation circuits can be used to protect the load circuit boards, including the connectors mounted on these load circuit boards, from an anomalous behavior of the electric power. The oscillation mitigation circuits are coupled between wire bundles forming a portion of the electric power supply and the connectors mounted on the load circuit boards.

Abstract: A system to convert the heat collected by solar thermal collectors into electricity using a Rankine cycle generator with multiple working fluids and multiple temperature-level heat sources is disclosed.

Abstract: A combined cycle power plant system and methods of operation so as to minimize consumption of cooling water utilizes exhaust from a combustion turbine to generate steam for power generation in a steam turbine topping cycle. The exhaust steam from the steam turbine topping cycle is utilized to vaporize an organic working fluid in an organic working fluid bottoming cycle, where vaporized organic working fluid expanded across a turbine generates additional power. Exhaust gas from the organic working fluid bottoming cycle is condensed utilizing an air-cooled heat exchanger. Heat exchange bundles of the air-cooled heat exchanger are preferably arranged horizontally relative to the ground to maximize efficiency. Turbine inlet cooling is employed at the combustion turbine to recapture energy lost in the system. A thermal energy storage tank may be utilized in conjunction with the turbine inlet cooling to supply chilling water to the system.

Abstract: An air-cooled condenser system for an Organic Rankin Cycle power plant includes a support structure formed of a plurality of truss members that are coupled together in a spaced apart orientation to horizontally support a plurality of side-by-side condenser bundles. A plurality of fans are likewise supported by the truss members and are disposed above the condenser bundles to draw air across the condenser bundles. Each fan extends over at least two condenser bundles and preferably at least three bundles. An air plenum is provided to establish a minimum separation between each fan and its corresponding condenser bundles so as to fluidly couple each fan to at least two condenser bundles, while at the same time decoupling the air inlet and air exit for the system, thereby minimizing air recirculation.

Abstract: A method for cooling inlet air to a gas turbine is provided. For example, a method is described including passing inlet air through a cooling coil that includes an opening for receiving the inlet air and that is operably connected to a gas turbine power plant. The gas turbine power plant may include at least one gas turbine, and at least one gas turbine inlet which receives the inlet air. The method may further include passing circulating water through a water chiller at a first flow rate to reduce the temperature of the circulating water, the water chiller including a conduit through which the circulating water is capable of passing and passing the circulating water having the first flow rate through the cooling coil in an amount sufficient to lower the temperature of the inlet air.
