Abstract

Systems, apparatus, methods, and techniques of assembly of discrete modules of a control panel are disclosed. The modules can be independently wired, tested, and installed into a control panel. Module definitions are defined specifying components to perform the electrical function, a mechanical arrangement of the components, electrical connections, and logical interactions of the module. A bill of materials can be generated based on a designation of a set of modules for a control panel and the module definitions. Modularly assembled control panels are disclosed. An assembly frame is described herein for temporarily mounting components of a module for independent assembly of a control module and for eventual removal and installation into a control panel frame. The assembly frame may include a faceplate frame and side frames and temporary mounting features.

First claim

The invention claimed is:

1. A control panel for operation of an electrical power system, comprising:
a control panel frame including a front support and a back support; and
a first module and a second module;

wherein the first and second modules are each selected from a plurality of pre-defined modules, and wherein each module of the plurality of pre-defined modules comprises discretely wired and self-contained to independently perform an electrical function pertaining to operation of an electrical power system, each module of the plurality of pre-defined modules including:
components to perform the electrical function;
the components comprising a mechanical arrangement to facilitate human interaction, use, and independent manufacture and testing of the module;
electrical connections configured to interface with electrical connections of other modules of the plurality of modules and with other equipment of the power system;
logical connections between the components to perform the electrical function; and
logical interfaces for logical connection with other modules or other equipment of the power system,
wherein each module is mounted in the control panel frame.

2. The control panel of claim 1 , wherein
the front support of the control panel frame is configured to receive a module face plate,
the first and second modules each comprise the module faceplate to be mounted to the front support and
the front support is configured to support and present components configured for human interaction.

3. The control panel of claim 1 , wherein the components of the first module include an interface to connect to an interface of the second module and through which communication occurs between the first module and the second module.

4. The control panel of claim 1 , wherein at least one of the modules includes an interface for configuring settings according to specifications of an installation site of the control panel.

5. The control panel of claim 1 , wherein the control panel is to address an application in operating the electrical power system.

6. The control panel of claim 5 , wherein the application in operating the electrical power system comprises one of: line protection, control, and monitoring; transformer protection, control and monitoring; bus protection, control and monitoring; feeder protection, control and monitoring; and capacitor bank protection, control and monitoring.

7. The control panel of claim 5 , wherein the application comprises a plurality of functions pertaining to operation of the electrical power system each performed by a module.

8. The control panel of claim 1 , wherein each module of the plurality of modules is configured for compatibility with every other module of the plurality of modules.

9. The control panel of claim 1 , wherein the first and second modules are each pre-defined by data specifying the components to perform the electrical function, a mechanical arrangement of the components, the electrical connections, and the logical interaction of the components to perform the electrical function, wherein each module is designed to be independently wired, tested, and installed in a control panel.

10. The control panel of claim 1 , further comprising one or more wiring harnesses creating one or more of the electrical connections between the components.

11. The control panel of claim 10 , wherein the one or more wiring harnesses further create electrical connections at the points of interface with other modules and other equipment of the power system.

12. The control panel of claim 1 , wherein the control panel frame has dimensions according to a predetermined standard size.

13. The control panel of claim 1 , further comprising one or more cross braces extending between the front support and the back support, the one or more cross braces to delineate between the first and second modules.

14. The control panel of claim 13 , wherein the first and second modules each comprise one or more DIN rails extending between two cross braces, each of the one or more DIN rails configured to have mounted thereto components of the module.

15. The control panel of claim 1 , wherein the electrical function pertaining to operation of the electrical power system is one of distance protection, overcurrent protection, transformer differential protection, differential protection, voltage protection, voltage control, frequency control, breaker control, peak metering, demand metering, revenue metering, and power quality metering.

16. The control panel of claim 1 , wherein the electrical function pertaining to operation of the electrical power system is one of distance protection, overcurrent protection, transformer differential protection, differential protection, voltage protection, voltage control, frequency control, breaker control, peak metering, demand metering, revenue metering, and power quality metering.

17. A control panel for operation of an electrical power system, comprising:
a control panel frame including a front support and a back support;
one or more cross braces extending between the front support and the back support, the one or more cross braces to delineate between a first module and a second module; and
the first module and a second module;
wherein the first and second modules are each selected from a plurality of pre-defined modules, and wherein each module of the plurality of pre-defined modules comprises discretely wired and self-contained to independently perform an electrical function pertaining to operation of an electrical power system, each module of the plurality of pre-defined modules including:
components to perform the electrical function;
the components comprising a mechanical arrangement to facilitate human interaction, use, and independent manufacture and testing of the module;
electrical connections configured to interface with electrical connections of other modules of the plurality of modules and with other equipment of the power system;
logical connections between the components to perform the electrical function; and
logical interfaces for logical connection with other modules or other equipment of the power system; and
one or more DIN rails extending between two cross braces, each of the one or more DIN rails configured to have the components mounted thereto;

wherein each module is mounted in the control panel frame.
