Power protection and remediation
First Claim
1. A computer-implemented method implemented in a data processing apparatus, the method comprising:
- for a power customer location that receives power from a power source, the power customer location including a plurality of local distribution branches and wherein each local distribution branch includes a plurality of electrical loads;
receiving reporting data from each of a plurality of power management devices, each power management device coupled to a respective one of the electrical loads and providing power management for the electrical load;
wherein for each power management device the reporting data includes;
power characteristics as detected at an electrical load on the distribution branch; and
a time at which the power characteristics were detected;
determining, from the reporting data, a historical power environment profile for the customer location that describes historical power characteristics for each of the electrical loads on the distribution branches, comprising;
determining, for each electrical load;
determining, for a plurality of corresponding times, an operational state of the electrical load at the corresponding time, wherein the operational states include a healthy state during which the electrical load is not experience a malfunction and a malfunction state during which the electrical load is experiencing a malfunction;
determining, from the operational states at the corresponding times, transitions from a healthy state to a malfunction state;
determining, for each transition from a healthy state to a malfunction state, respective sets of power characteristics at the corresponding times for the transitions, each respective set of power characteristics being for a different electrical load;
determining, based on the historical power environment profile, a combination of electrical loads that results in at least a first electrical load operating in a healthy state inducing power-related malfunctions in at least a second electrical load, comprising;
comparing the respective sets of power characteristics at the corresponding times for the transitions to each other; and
determining that power characteristics for the at least one electrical load of a first type while the at least one electrical load is operating in a healthy state have a positive correlation with transitions from a healthy state to a malfunction state for at least one electrical load of a second type that is different from the first type; and
generating, in response to the determination, an alert that describes the combination of electrical loads.

Abstract
Methods, systems, and apparatus for collect historical power consumption data and power consumption statistics for one or more locations and devices at the location to generate historical power consumption and health data (“historical data”). The historical data are used to develop and provide multiple different protection and monitoring functions. The system may be deployed within a single customer location, e.g., within a building or a plant, and local analytics are developed at the location. Alternatively, the system may be distributed among several locations for a particular customer or multiple different customers and include cloud-based analytics in addition to, or instead of, local analytics.
