Abstract: A method and system allows for substantially real-time monitoring of the operational dynamics of power plants and other components comprising an AC power grid, by using information collected from a network of power grid frequency detection and reporting devices. The invention allows for the substantially real-time detection and reporting of certain power grid events such as power plant trips.

Abstract: A conductor configuration and a power flow of an electric power transmission line set is determined at a location along the line set, and positions in a substantially planar area that is transverse to the line set are determined where a predetermined change in the power flow results in a maximum change in the magnetic field at the positions. A system for monitoring power flow includes a plurality of magnetic field monitors placed at the selected positions, and a central processing facility for communicating the power flow to an end user. A method for monitoring power flow includes selecting positions for placement of a plurality of magnetic field monitors, placing the monitors, determining a power flow, and communicating the power flow to an end user.

Abstract: In an exemplary implementation of a method and system for determining the direction of fluid flow, one or more sound transducers are positioned in proximity to a conduit, each such sound transducer generating a signal representative of a selected characteristic of acoustic waves emanating from the conduit. Such signals are collected and analyzed to determine a threshold value for the selected characteristic (e.g., frequency) indicative of a change in the direction of fluid flow through the conduit. Based on whether subsequent measurements of the selected characteristic (e.g., frequency) are above or below the threshold value, the direction of fluid flow can be predicted and/or a change in the operational state of a component associated with the conduit can be identified.

Abstract: A method and system for monitoring fluid flow, such as fluid flow through pipelines or similar conduits for delivering natural gas, crude oil, and other similar liquid or gas energy commodities, relies on the measurement of acoustic waves generated by the fluid, thus allowing for monitoring of the flow rate without direct access to the fluid. Furthermore, the method and system allows for estimation of the operational dynamics of components or facilities of the production, transportation, storage, and distribution systems for the energy commodities.
