Method for early detection and anticipatory control of consumer-end load shedding in an electrical grid, and apparatus for carrying out the method

摘要

A method for early detection and anticipatory control of consumer-end load shedding in a single-phase or polyphase electrical grid supplied with single phase or polyphase by at least one generator driven by at least one rotating machine includes measuring a current and a voltage between the at least one generator and the electrical grid and/or a current and a voltage in the electrical grid, deriving at least one signal from the measured current and voltage and using the at least one derived signal to act on the at least one rotating machine.

1. A method for early detection and anticipatory control of consumer-end load shedding in a single-phase or polyphase electrical grid supplied with single phase or polyphase by at least one generator driven by at least one rotating machine, the method comprising:
measuring a current and a voltage, the current and the voltage being measured between the at least one generator and the electrical grid, in the electrical grid or at both locations; deriving at least one signal from the measured current and voltage; using the at least one derived signal and a gradient signal generated from the at least one derived signal to at least partially reduce a load on the at least one rotating machine, wherein the at least one derived signal and the gradient signal are sent to a regulator of emitted power of the at least one rotating machine so as to influence a power output of the at least one rotating machine during a load shedding in the grid; and subsequently matching a generation of and demand for electric power.
