Abstract

An energy monitoring and management system and method are provided herein. The system and method centralize load metering by utilizing at least one sensor for observing load characteristics (e.g., Volts, Amperes, Watts, active energy . . . ) communicatively coupled via a backplane to a waveform analyzer component of a control component. The waveform analyzer component generates metered data values after receiving input from the at least one sensor. Subsequently and if so desired, the control component can send a control signal to the load to alter the state of the load or simply reduce the power to a load. Such input, output, and processing functionality, according to an aspect of the present invention, are employed using a backplane to facilitate high-speed communication among components and to allow metered data to be centrally stored, manipulated, analyzed or communicated to other components or sub-components.

Claims

1. An industrial automation control system, comprising:

a waveform analyzer component configured to receive data from a plurality of sensors associated with a plurality of loads, the waveform analyzer further configured to analyze the data and determine metered data; and

a load control component configured to;

retrieve a power company billing schedule from a power company'"'"'s web page or a power company'"'"'s database, and

regulate rate of energy distributed to the plurality of loads based upon the metered data and the power company billing schedule.

2. The system of claim 1, wherein the load control component is further configured to employ a load optimization algorithm on the metered data.

3. The system of claim 2, wherein the load optimization algorithm factors in at least energy cost associated with an operation rate of a machine associated with the at least one load at the rate of energy and cost of wear or failure associated with the operation rate of the machine associated with the at least one load at the rate of energy.

4. The system of claim 1, wherein a subset comprising at least two loads of the plurality of loads are grouped into a class and the load control component is further configured to regulate the rate of energy to the subset of loads in the class using a common action.

5. The system of claim 1, wherein the load control component communicates with other load control components to determine a load control strategy for the plurality of loads.

6. The system of claim 5, wherein the control strategy is determined at least in part based upon data captured by the plurality of sensors.

7. The system of claim 6, wherein the plurality of sensors collect data relating to the health of a load.

8. The system of claim 7, wherein the waveform analyzer component utilizes the data captured by the plurality of sensors relating to the health of the load to determine power data.
