Abstract
The present disclosure provides systems and methods for monitoring power consumption of individual devices on an electric power system. A monitoring system may identify unique power characteristics of each device. The monitoring system may use the identified unique power characteristics to disaggregate electric data representative of the power consumption of all of the devices on the electric power system into portions associated with each device.
Claims9
An electrical monitoring device for proactive maintenance of an electrical appliance in an electrical power distribution system, comprising:
- at least two current sensors to measure current values on at least two electrical lines of an electrical power distribution system;
- an input to receive aggregated measured electric power values from the at least two current sensors representing electric power consumption of a plurality of electrical appliances, including a first electrical appliance;
- a memory to store a profile for each of the plurality of electrical appliances, wherein each profile includes an electrical signature and historical baseline electrical power consumption values of each respective electrical appliance;
- a signal analyzer in electrical communication with the memory to:
- compare the stored electrical signatures with the aggregated measured electrical power values, and
- identify a plurality of profiles, including the profile of the first electrical appliance, that collectively correspond to the aggregated measured electrical power values;
- a disaggregator to separate the aggregated measured electric power values and identify real-time electric power values associated with the first electrical appliance;
- an anomaly detector to identify anomalous behavior of the first electrical appliance by comparing the separated, real-time electric power values of the first electrical appliance and the stored historical baseline electrical power consumption values of the electrical appliance;
- and
- a communication transceiver in communication with a local network computing device, the communication transceiver to utilize a network of local computing devices to transmit a service request for the electrical appliance.
