System and method for sequential application of power to electrical loads
View Patent ↗An energy management system for providing sequential application of power to electrical loads contains a series of electrical loads and at least one unit controller, wherein each unit controller connects to at least one electrical load and controls power application to the at least one electrical load. Each individual unit controller has a unique identification to allow for communication with the individual unit controller, wherein each unique identification has a unique power-on delay. The unit controller contains a memory and a processor configured by the memory to: determine if a power-off condition has occurred, being followed by a power-on condition, referred to as a powerup event; and enable delivery of power, after a powerup event, to the at least one electrical load in accordance with the unique power-on delay of the unit controller. A building controller or central server may instead provide sequential application of power.
1. An energy management system for providing sequential power application to more than one electrical load, the system comprising:
a series of electrical loads configured to receive power from a power source;
a plurality of unit controllers, wherein each unit controller is connected to a respective electrical load and controls power application to the electrical load, each individual unit controller being provided with a unique identification to allow for communication with the individual unit controller, wherein each unit controller is configured to calculate a unique power-on delay associated with the unique identification of the respective connected unit controller, wherein the each unique power-on delay is calculated as the unique identification of the specific unit controller multiplied by a minimum recovery time, the minimum recovery time comprising an amount of time required for the power source to recover from powerup of an electrical load, and wherein each of the plurality of unit controllers further comprises:
a memory; and
a processor configured by the memory to perform the steps of: (i) determining if a power-off condition has occurred, being followed by a power-on condition, the sequence of these conditions being referred to as a powerup event; and (ii) enabling delivery of power, after a powerup event, to the respective electrical load at a time corresponding to and in accordance with the calculated unique power-on delay of the unit controller applying power to the respective electrical load;
wherein the plurality of unit controllers are configured to deliver power after a powerup event in a non-overlapping sequential sequence to the series of electrical loads.
2. The energy management system of claim 1 , wherein the unique identification of each unit controller is provided by an associated dipswitch located on each unit controller.
3. The energy management system of claim 1 , wherein all of the electrical loads are located within the same building.
4. The energy management system of claim 1 , wherein the electrical loads are not all located within the same building.
5. The energy management system of claim 1 , wherein the electrical loads are selected from the group consisting of heating units, ventilation units, and air conditioning units.
6. The energy management system of claim 1 , wherein the unit controller is connected to more than one electrical load and is capable of controlling power application to the more than one electrical load.
7. The energy management system of claim 1 , wherein the energy management system further comprises an array of unit controllers, wherein each unit controller controls power application to one or more electrical loads.
8. An energy management system for providing sequential power application to more than one electrical load, comprising:
a series of electrical loads configured to receive power from a power source;
a series of unit controllers, wherein each unit controller is connected to at least one electrical load and wherein each individual unit controller is provided with a unique identification to allow for communication with the individual unit controller;
a building controller for controlling power application to at least one electrical load within the series of electrical loads, via communication with at least one unit controller associated with the at least one electrical load, wherein the building controller is configured to calculate a unique power-on delay associated with the unique identification of each of the at least one unit controllers, wherein the unique power-on delay is calculated as the unique identification of the at least one unit controller multiplied by a minimum recovery time, the minimum recovery time comprising an amount of time required for the power source to recover from powerup of an electrical load, and wherein the building controller further comprises:
a memory; and
a processor configured by the memory to perform the steps of: (i) determining if a power-off condition has occurred, being followed by a power-on condition, the sequence of these conditions being referred to as a powerup event; and (ii) enabling delivery of power, after a powerup event, to the at least one electrical load at a time corresponding to and in accordance with the calculated unique power-on delay of the unit controller applying power to the at least one electrical load;
wherein the building controller is configured to deliver power after a powerup event in a non-overlapping sequential sequence to the series of electrical loads.
9. The energy management system of claim 8 , wherein the unique identification of each unit controller is provided by an associated dipswitch located on each unit controller.
10. The energy management system of claim 8 , wherein all of the electrical loads are located within the same building and are selected from the group consisting of heating units, ventilation units, and air conditioning units.
11. The energy management system of claim 8 , wherein the electrical loads are not all located within the same building.
