Process Bus Definition

> Process bus is the combination of all interfaces

between the process and the SPACS communicating

data and information that can be shared between the

PIU and the SPACS functions.

> The process can be divided in three major parts: > The power process

> The auxiliary process

> Building/Substation process

Reduced Installation Costs

• Reduced costs due to the replacement of hundreds or

even thousands control cables with a limited number of

fiber optic cables

• Reduced costs due to the replacement of the wiring of

hundreds of copper wires to the panels’ terminal blocks

and then from the terminal blocks to the relay terminals

with the plugging in of a few pairs of fiber cables

• Reduced costs due to the requirements for testing of all

hard wired interfaces versus the testing of the GOOSE

messages based on advanced software tools

Other Benefits

• Improved safety

• Reduced probability for CT saturation

• Improved flexibility

• Reduced maintenance

• Improved interoperability

• Improved reliability

• Remote testing
