  • Patent number: 12271846
    Abstract: A dispatch advisor to assist in selecting operating conditions of a power plant that maximizes operational revenue is described. The dispatch advisor obtains a base load map for operating the power plant to meet base load power demands. The base load map includes a primary base load operating space for attaining target plant power output and efficiency, and an expanded base load portion for attaining higher plant power output and less than optimal efficiency. Both the primary base load operating space and the expanded base load portion associate power output and efficiency values of the power plant that result from a subset of operational parameter values for operating the power plant during base load. The dispatch advisor can transform the flexible base load map into one or more visualizations describing the revenue possibilities associated with operating the power plant based on operating values and attained power output and efficiency.

The mass damper includes a frame that is movable linearly along a base, which includes a track gear. A flywheel is in geared engagement with the track gear so as to be rotationally driven as the frame moves linearly relative to the base. A rotation damper is mounted on the frame and is geared engagement with the flywheel, the rotation damper producing a counter-torque against rotation of the flywheel that is proportional to a rotational velocity of the flywheel. The rotation damper has an electrical characteristic that is automatically adjusted to change the counter-torque and tune the mass damper.
