Embodiment Construction

[0018] Embodiments of the invention described herein relate to industrial machines that monitor their power usage and communicate with other industrial machines regarding their power usage. Industrial machinery is often used for those projects that use more than one industrial machinery and other related equipment. Power for industrial machinery and other equipment is often provided by the grid. However, the cost of supplying power is sometimes based on total or cumulative peak power usage. In order to prevent the total power usage for the system from exceeding a predetermined peak power usage, every industrial machine is equipped with a power control system. The power control system monitors power usage (e.g., actual power usage or expected power usage) of the industrial machine; communicates with other industrial machines regarding the power usage of the industrial machine and the power usage of other industrial machines; And regulating the operation of the industrial mach...

Abstract

A system includes a first industrial machine and a second industrial machine. The system also includes a power distribution system configured to provide power to the first industrial machine and the second industrial machine. The first industrial machine includes a first power control system configured to monitor power usage of the first industrial machine and send power usage information of the first industrial machine to a second industrial machine. The second industrial machine includes a second power control system configured to: monitor power usage of the second industrial machine, receive power usage information from the first industrial machine, and to control the power usage of the second industrial machinery.

Description

technical field [0001] The present invention relates to controlling the power usage of industrial machinery systems. Background technique [0002] Sometimes more than one industrial machine is used to complete large projects (eg, construction projects, mining projects, etc.). Industrial machinery and other equipment used in these projects are often powered by the grid. Energy companies can charge for electricity from the grid based on the highest total peak power being used. In other words, the cost of electrical power may be based on the highest cumulative peak power used by all industrial machinery and equipment receiving power from the grid at a particular site. Therefore, the project manager has an incentive to keep the overall power usage low during the project. However, the project manager also has an incentive to operate the machinery at maximum efficiency so that the project is completed on time. [0003] Achieving the balance between maximum efficiency and minim...
