Abstract: Systems and methods for governing a signal waveform of a signal flowing through a component of a power transmission system that includes a plurality of switch-mode power processors and may be a polyphase system. At least one of current and voltage is integrally monitored at each of a plurality of locations on the power system and is characterized relative to specified constraints. When a monitored voltage or current is outside of the specified constraints, the voltage or current is modified by changing at least one of the time delay or phase characteristics of at least one of the source, load and transmission elements on the power transmission system.

Abstract: An apparatus and method are provided for detecting and tracking hailstorms to generate warning signals to installed wind turbines, and to control wind turbine blade positioning and rotation to minimize blade surface areas presented to possible hail impacts. The hailstorm detecting and tracking sensor used for the present invention can be located either at a remote location from a wind turbine installation or at the wind turbine location. Multiple wind turbines at single or multiple locations can be protected using the present invention. Minimization of wind turbine blade presented surface areas to hail impacts can be achieved by turning blade edges into the wind, stopping rotation of rotors to which blades are attached, or by turning the rotor rotation axis ninety degrees to on-coming wind. Any one or a combination of these blade reorientations or functionings can be implemented using the present invention.
