VIRTUAL BRANCH LOAD MANAGEMENT

摘要

A load estimation algorithm for automatically estimating power consumed by each branch load connected to circuit breakers in a power distribution panel (PDP) without requiring individual current sensing at each branch. The load estimation algorithm can be operated in a manual mode, remote manual mode, or an agile mode. In manual mode, the user turns off individual circuit breakers in an ordered sequence, and the load estimation algorithm calculates the difference in the power consumption when all loads are connected versus when one load is disconnected to estimate the power consumption of the disconnected load. In the remote manual mode, the circuit breakers are remotely operable, so that load estimation algorithm controls their states through software. In agile mode, the algorithm continuously attempts to estimate power consumption of each load connected to the PDP by comparing present load estimates with previous load estimate and flagging any discrepancies.
