Abstract

A system for interconnecting electrical network control centers and building management systems is provided. The interconnected system monitors the operational status of the electrical network from a control center. In response to detecting the signature of an imminent electrical network event, the control center transmits a signal to the building management system. In response to receiving the signal, the building management system initiates a series of actions to mitigate or reduce the impact of the electrical network event.

Claims

1. An electrical network event system comprising:

an electrical network control center configured to monitor in real-time an operation status of an electrical network, the electrical network control center further having a first processor responsive to executable computer instructions when executed on the first processor for receiving a first signal from sensors on the electrical network, and evaluating the first signal to determine if an event is imminent;

wherein the first processor is configured for transmitting a second signal in response to determining the event is imminent to a remote building management system for executing a series of predetermined actions.

2. The electrical network event system of claim 1 wherein the remote building management system operably coupled to communicate with the electrical network control center, the remote building management system further having a second processor responsive to executable computer instructions when executed on the second processor for receiving the second signal and executing a first series of predetermined actions in response to the second signal.

3. The electrical network event system of claim 2 wherein the first series of predetermined actions is chosen from a group comprising:

stopping elevators at a nearest floor, adjusting a building heating ventilation and air conditioning system, initiating operation of a backup power system, and adjusting a lighting system.

4. The electrical network event system of claim 3 wherein the second processor is further responsive to executable computer instructions for transmitting an alert signal to a building operator in response to the second signal.

5. The electrical network event system of claim 2 wherein the first processor is further responsive to executable computer instructions when executed on the first processor for categorizing the event and transmitting the second signal when the event is a first category event and a third signal to the remote building management system when the event is a second category event.

6. The electrical network event system of claim 5 wherein the second processor is further responsive to executable computer instructions when executed on the second processor for receiving the third signal and executing a second series of predetermined actions in response to the third signal.

7. The electrical network event system of claim 6 wherein the second series of predetermined actions is chosen from a group comprising:

reducing a number noncritical electrical loads, modulating heating ventilation and air conditioning systems, increasing thermostat temperatures, and turning off lights.

8. The electrical network event system of claim 7 wherein the first series of predetermined actions is chosen from a group comprising:

stopping elevators at a nearest floor, initiating operation of a backup power system, and alerting a building operator.

9. A building management system comprising:

a building management controller having an input for receiving a first signal from an electrical network control center;

wherein the building management controller includes a processor responsive to executable computer instructions for executing a series of predetermined actions to reduce electrical power consumption in response to receiving the first signal.

10. The building management system of claim 9 wherein the series of predetermined actions is chosen from a group comprising:

stopping elevators at a nearest floor, adjusting a building heating ventilation and air conditioning system, initiating operation of a backup power system, and adjusting a lighting system.

11. The building management system of claim 10 wherein the building management controller is further configured for receiving and transmitting signal to a plurality of building subsystems, the plurality of building subsystems includes at least one of a backup power system, a lighting system, a heating ventilation and air conditioning system, a transportation system and a tenant energy management system.

12. The building management system of claim 9 wherein the series of predetermined actions includes a first series of predetermined actions and a second series of predetermined actions.

13. The building management system of claim 12 wherein the processor is further responsive to executable computer instructions for executing the first series of predetermined actions to reduce electrical power consumption in response to receiving the first signal.

14. The building management system of claim 13 wherein the first series of predetermined actions is chosen from a group comprising:

stopping elevators at a nearest floor, initiating operation of a backup power system, and alerting a building operator.

15. The building management system of claim 13 wherein the processor is further responsive to executable computer instructions for executing the second series of predetermined actions to reduce electrical power consumption in response to receiving a second signal.

16. The building management system of claim 15 wherein the second series of predetermined actions is chosen from a group comprising:

reducing a number noncritical electrical loads, modulating heating ventilation and air conditioning systems, increasing thermostat temperatures, and turning off lights.

17. A method of operating an interconnected electrical network event system comprising:

monitoring a plurality of sensors coupled to an electrical network;

receiving a first signal from each of the plurality of sensors;

evaluating the first signal;

determining from the first signal that an electrical network event is imminent; and

,
