Abstract
An automatic power restoration device has a modifiable end point. The end point is indicative of the operational parameters of the automatic power restoration device. A user can modify the end point and thus the operational parameters of the automatic power restoration device. The end point can be modified according to the protection characteristics of other fault protection devices within a power system.
Claims17
An automatic power restoration system connected to a power system comprising:
- an automatic power restoration device;
- and
- a control device, the control device comprising:
- a microprocessor;
- a memory;
- and
- a software application supporting a programmable end point, the end point indicative of the operational characteristics of the automatic power restoration system and programmable to coordinate automatic power restoration device curve characteristics with fault protection device curve characteristics by modifying the end point of the automatic power restoration system.
A power distribution system having power distribution equipment, the system comprising:
- at least one automatic power restoration system for restoring power to the power distribution equipment, wherein the automatic power restoration system supports a programmable end point indicative of the operational characteristics of the automatic power restoration system;
- at least one fault protection device capable of ceasing power to the power distribution equipment and having operational parameters;
- and
- at least one automatic power restoration control device capable of coordinating automatic power restoration system curve characteristics with fault protection device curve characteristics by modifying the end point of the automatic power restoration system.
A method for distributing electrical power in a power distribution system having power distribution equipment, comprising:
- providing at least one automatic power restoration system for restoring power to power distribution equipment, wherein the automatic power restoration system supports a programmable end point representing a point at which the automatic power restoration system ceases to provide power to the power distribution equipment;
- providing at least one fault protection device capable of opening a conductive line in the power distribution system and having operational parameters, and
- coordinating automatic power restoration system curve characteristics with fault protection device curve characteristics by modifying the end point of the automatic power restoration system.
A method for reducing the operational cost of an automatic power restoration device, the method comprising:
- providing at least one automatic power restoration device for restoring power to power distribution equipment, wherein the automatic power restoration device supports a programmable end point representing a point at which the automatic power restoration device ceases to provide power to the power distribution equipment;
- providing at least one fault protection device capable of opening a conductive line in the power distribution system;
- and
- coordinating automatic power restoration device curve characteristics with fault protection device curve characteristics by modifying the end point of the automatic power restoration device,
- wherein the modifiable end point of the automatic power restoration device is modified to coordinate with operational parameters of the fault protection device such that the operational characteristics of the automatic power restoration device do not coincide with the operational parameters of the fault protection device.
