A SYSTEM FOR ROBUST LOAD DISAGGREGATION

摘要

An electrical power data processing system has an interface to an electricity power sensor (11) and a processor (12) adapted to perform pre-processing of said sensor data to provide data (13) for load disaggregation. The processor (12) detects data failure and disables load disaggregation on data loss, incomplete data sets, corrupt data, inconsistent data, and unsynchronised data. Also, it automatically detects data loss for a parameter by detecting lack of time synchronisation between parameters of a given electrical reading in response to an event. The event may be a power event having a concurrent variation of a number of electrical parameters. The processor is determines if a current sensor data periodicity pattern falls outside periodicity rules.
