Abstract
Disclosed are methods and apparatus to improve the stability of power distribution systems. The methods and apparatus include using edge processing to decrease the detection and reaction times associated with disturbances within the power distribution system. The edge processor can compare sampled phasor data with center of inertia data associated with the power distribution system.
Claims18
A method for ascertaining the stability of a power distribution system, comprising:
- a. calculating the center of inertia of a power distribution at a first location,
- b. sampling a phasor representing the properties of electricity flowing into, out of, or through a segment of said power distribution system using five tertiary sampling devices located at least 10 miles from said first location, and
- c. using five edge data processors located at least 10 miles from said first location with each of said edge data processors being communicatively coupled to a respective one of said tertiary sampling devices to compare data extracted from said phasor to said center of inertia to ascertain the instability between said electricity sampled by said tertiary sampling device and the rest of said power distribution system;
- wherein said calculation of said center of inertia is performed at least 10 miles from said edge data processor.

A system for ascertaining the stability of a power distribution system, comprising:
- a. a plurality of sampling devices each configured to sample phasor information at a plurality of locations within a power distribution system wherein each phasor represents properties of electricity flowing through different portions of said power distribution system,
- b. a central data processor for calculating a center of inertia of the power distribution system using data from said plurality of sampling devices, and
- c. at least 5 edge data processors at least 10 miles from said central data processor,
- with each of said edge data processors communicatively coupled to a tertiary sampling device that is configured to sample phasor information of electricity flowing through, into, or out of said power distribution system;
- wherein each of said edge data processors is configured to receive center of inertia information from said central data processor and compare said phasor information from said tertiary sampling device to said center of inertia information to ascertain the stability between the electricity sampled by said tertiary sampling device and the rest of the power distribution system.
