Systems and methods for classifying an electric power source powering a communication node after an apparent conclusion of a power outage

A method for classifying an alternating current (AC) electric power source powering a first node of a communication network after an apparent conclusion of a power outage, the method comprising:

• receiving, at a classification system, measurement data from a sensor that is transmitted to the classification system via one or more paths of the communication network, the one or more paths of the communication network being separate from an AC electric power grid that serves the first node such that the measurement data is transmitted to the classification system out of band with respect to the AC electric power grid that serves the first node, the measurement data representing one or more characteristics of AC electric power provided to the first node;
• comparing, at the classification system, (i) an electrical characteristic of AC electric power provided to the first node at a time t1, the time t1 being after the apparent conclusion of the power outage, to (ii) a range of an electrical characteristic of AC electric power provided to the first node during a time period Th, the time period Th being a historical time period before the power outage;
• performing, at the classification system, a first classification indicating that a generator, and not the AC electric power grid that serves the first node, is powering the first node at the time t1, in response to the electrical characteristic of the AC electric power provided to the first node at the time t1 being outside of the range of the electrical characteristic of the AC electric power provided to the first node during the time period Th;
• performing, at the classification system, short-term statistical analysis of the measurement data to determine one or more short-term statistical difference values between (i) electrical characteristics of AC electric power provided to the first node over a first time duration, the first time duration being before the power outage, and (ii) electrical characteristics of AC electric power provided to the first node over a second time duration, the second time duration being after the apparent conclusion of the power outage;
• performing at the classification system, a second classification indicating that the generator, and not the AC electric power grid that serves the first node, is powering the first node during the second time duration, in response to the one or more short-term statistical difference values meeting one or more second threshold conditions;
• performing, at the classification system, long-term statistical analysis of the measurement data to determine one or more long-term statistical difference values between (i) electrical characteristics of AC electric power provided to the first node over a third time duration, the third time duration being before the power outage, and (ii) electrical characteristics of AC electric power provided to the first node over a fourth time duration, the fourth time duration being after the apparent conclusion of the power outage;
• and
• performing, at the classification system, a third classification indicating that the AC electric power grid that serves the first node is powering the first node during the fourth time duration with an operating point reset, in response to the one or more long-term statistical difference values meeting one or more third threshold conditions.

• identifying occurrence of the power outage from magnitude of voltage of electric power provided to the first node having dropped below an acceptable range;
• after magnitude of voltage of electric power provided to the first node has risen to the acceptable range to indicate the apparent conclusion of the power outage determining, at the classification system, a difference value representing a difference between (i) a portion of the measurement data generated by the sensor before the power outage and (ii) a portion of the measurement data generated by the sensor after the apparent conclusion of the power outage;
• and
• determining, based on the difference value, whether the first node is being powered by a generator or by the AC electric power grid that serves the first node, after the apparent conclusion of the power outage.
