Grid event detection
First Claim
1. A method performed by data processing apparatus, the method comprising:
- receiving, by a data processing apparatus, signal characteristic data that specify signal characteristic values for signals that are received over each of a plurality of communications channels of a power line communications network;
determining, by the data processing apparatus, that the signal characteristic values for the signals that are received over at least one of the communications channels are outside of a baseline signal value range;
identifying an endpoint that communicates over the at least one communications channel;
determining that a set of the signal characteristic values matches one of a plurality of grid event signatures for the identified endpoint, each of the grid event signatures being indicative of a particular grid event corresponding to an impedance change; and
providing data that identify the endpoint and the particular grid event for the grid event signature that is matched by the set of signal characteristic values.

Abstract
Methods, systems, and apparatus, including computer programs encoded on a computer storage medium, for detecting grid events. In one aspect, a method includes receiving signal characteristic data that specify signal characteristic values for signals that are received over each of a plurality of communications channels of a power line communications network. A determination is made that the signal characteristic values for the signals that are received over at least one of the communications channels are outside of a baseline signal value range. An endpoint that communicates over the at least one communications channel is identified, and a determination is made that a set of the signal characteristic values for the identified endpoint matches one of a plurality a grid event signatures for the identified endpoint. Data that identify the endpoint and a particular grid event that is represented by the matched grid event signature are provided.
