EECS Colloquium
Abstract
Increased interest in energy scorekeeping, load forecasting, and improved control of electricity-consuming equipment has focused attention on instrumentation for data collection in the electric distribution systems of buildings (and other arenas, including transportation systems). For example, electric utilities and savvy commercial and industrial facilities managers want a means of acquiring detailed energy usage data with a minimal installation effort. Knowledge of the mix of operating loads can be used by the utility to create more accurate load models for stability assessment. Facilities operators can use this knowledge to balance the load and harmonic content of different parts and phases of their electrical distribution system, improving economy and load performance.
This talk will describe a multiscale transient event detection algorithm that can identify the operating schedule of individual electrical loads in a building. Identifications of individual loads are made strictly based on profiles observed in the aggregated current waveforms available at the service entry. By providing the ability to associate specific waveform features with specific loads, the transient event detector enables nonintrusive monitoring of the health of critical loads, and also the determination of the impact of their operation on power quality.
