Abstract

The present disclosure describes system and methods for inferring energy usage at multiple levels of granularity. One embodiment describes an industrial automation system including a first industrial automation component, a first sensor coupled to the first industrial automation component, in which the first sensor measures a first amount of power supplied to the first industrial automation component, a second industrial automation component that couples to the first industrial automation component, and an industrial control system that infers energy usage by the first industrial automation component and the second industrial automation component based at least in part on the first amount of power supplied to the first industrial automation component.

First claim

The invention claimed is:

1. An industrial automation system, comprising:
a first industrial automation component;
a first sensor coupled to the first industrial automation component, wherein the first sensor is configured to measure a first amount of power supplied to the first industrial automation component;
a second industrial automation component electrically coupled to the first industrial automation component; and
an industrial control system communicatively coupled to the first sensor, the first industrial automation component, and the second industrial automation component, wherein the industrial control system is configured to:
infer energy usage by the first industrial automation component and the second industrial automation component based at least in part on the first amount of power supplied to the first industrial automation component measured by the first sensor; and
control operation of the first industrial automation component, the second industrial automation component, or both based at least in part on the energy usage inferred from first amount of power supplied to the first industrial automation component to facilitate improving energy usage efficiency of the industrial automation system.

2. The industrial automation system of claim 1 , wherein the industrial control system is configured to infer a portion the energy usage attributed to the first industrial automation component based at least in part on a model of the first industrial automation component.

3. The industrial automation system of claim 2 , wherein the model is calibrated based at least in part on one or more manufacturer specifications associated with the first industrial automation component, previous operation of the first industrial automation component, or any combination thereof.

4. The industrial automation system of claim 2 , wherein the industrial control system is configured to verify the model of the first industrial automation component by:
determining actual energy usage associated with the first industrial automation component; and
adjusting the model such that the portion of the energy usage determined with model more closely approximates the actual energy usage.

5. The industrial automation system of claim 4 , wherein the actual energy usage associated with the first industrial automation component is determined based on a measurement of energy usage acquired by a second sensor electrically coupled between the first industrial component and the second industrial automation component.

6. The industrial automation system of claim 1 , wherein the industrial control system is configured to infer a portion the energy usage attributed to the second industrial automation component by:
determining a second amount of power used by the first industrial automation component; and
subtracting the second amount of power used by the first industrial automation component from the first amount of power measured by the first sensor.

7. The industrial automation system of claim 1 , wherein the first industrial automation component is configured to provide a second amount of power to the second industrial automation component.

8. The industrial automation system of claim 1 , wherein the first industrial automation component comprises a drive and the second industrial automation component comprises a motor.

9. The industrial automation system of claim 1 , wherein the industrial automation system is a material handling system, a packaging system, a manufacturing system, processing system, a batch processing system, or any combination thereof.

10. The industrial automation system of claim 1 , comprising a plurality of cells, wherein each cell of the plurality of cells is configured to perform at least one operation in the industrial automation system, and wherein the first industrial automation component and the second industrial automation component are part of a first cell of the plurality of cells.

11. A method comprising:
receiving, via at least one processor, an indication of a first amount of power provided to a first industrial automation component from a first sensor;
inferring, via the at least one processor, first energy usage associated with the first industrial automation component based at least in part on a model of the first industrial automation component and the first amount of power;
inferring, via the at least one processor, second energy usage associated with a second industrial automation component based at least in part on the first amount of power provided to the first industrial automation component and the first energy usage associated with the first industrial automation component, wherein the first industrial automation component is configured to provide a second amount of power to the second industrial automation component; and
controlling, via the at least one processor, operation of the first industrial automation component, the second industrial automation component, or both based at least in part on the first energy usage associated with the first industrial automation component and the second energy usage associated with the second industrial automation component to facilitate improving energy usage efficiency.

12. The method of claim 11 , wherein the second amount of power provided to the second industrial automation component is not directly measured by a second sensor associated with the second industrial automation component.

13. The method of claim 12 , wherein the second amount of power comprises a voltage and a current provided to the second industrial automation component.

14. The method of claim 11 , comprising:
measuring actual energy usage associated with the first industrial automation component via a second sensor; and
adjusting the model based on the actual energy usage.

15. The method of claim 11 , comprising:
determining a third amount of power used by the first industrial automation component; and
determining the first energy usage associated with the first industrial automation component, the second energy usage associated with the second industrial automation component, or both based at least in part on a difference between the third amount of power used by the first industrial automation component and the first amount of power provided to the first industrial automation component.

16. The method of claim 11 , wherein the first industrial automation component is a motor drive and the second industrial automation component comprises a controller, an input/output (I/O) module, a motor control center, a motor, a human machine interface (HMI), an operator interface, a contactor, a starter, a drive, a relay, a protection device, switchgear, a compressor, a scanner, a gauge, a valve, a flow meter, or any combination thereof.

17. An industrial automation system comprising:
a first group of industrial automation components;
a sensor coupled to the first group of industrial automation components, wherein the sensor is configured to measure an operational parameter of the first group of industrial automation components;
a second group of industrial automation components related to the first group of industrial automation components; and
an industrial control system communicatively coupled to the sensor, the first group of industrial automation components, and the second group of industrial automation components, wherein the industrial control system is configured to:
determine energy usage by the first group of industrial automation components and the second group of industrial automation components based at least in part on the operati
