Abstract
This application discloses a system that may comprise at least a portion of a supply network. The system may further comprise a load controller that controls current flow with a current level of I1 into a load network that provides power to one or more loads from the at least a portion of the supply network according to a preprogrammed load curve. The system may also comprise a protection system that isolates the at least a portion of the supply network from the load controller in response to detecting a current pattern that is inconsistent with the preprogrammed load curve.
Claims26
A load system, comprising:
- a load controller;
- at least one processor;
- and
- a computer-readable medium containing instructions that, when executed by the at least one processor, cause the load system to perform operations on a load control curve comprising:
- specifying a current draw or supply of the load controller as a function of time;
- including at least two current setpoints;
- and
- including transitions between the at least two current setpoints, the transitions having specified ramp rates;
- and
- configuring the load controller to draw from or supply current to a distribution circuit connected to the load controller based on the load control curve.
A supply system, comprising:
- at least one processor;
- and
- a computer-readable medium containing first instructions that, when executed by the at least one processor, cause the supply system to perform operations on a load control curve comprising:
- specifying a current drawn from or supplied into a distribution circuit as a function of time;
- and
- detecting a fault associated with the distribution circuit by comparing a present current drawn from or supplied to the distribution circuit to the load control curve.
