Challenges of Protection & Control Today

Issues Impacting: Increasing amount of work and

special request

Limited trained or available resources

Training resources

Tools that do not easily exchange data

Different sources for data or redundant sources

Synching data/keeping databases up to date

Why Automate?

Use of asset management systems, short-circuit tools, protection coordination tools and automation for improving the protection engineering process

Automate Data Entry Eliminate as much as is

practical

Cost vs Benefit

Reduce errors/Save time

Automate Study Provide consistency

Alleviate burden on protection engineers


Automate Presentation of Study Results Focus protection engineers on areas

needing attention



Automate Reports Provide consistency

Custom Complex Logic

Step 1: Ignore all ground and neg. seq. elements (Containing G and Q in

their code)

Step 2: Ignore the phase elements that are used in trip but are disabled

in the relay

Step 3: Ignore the Ai blocks that contain disabled elements

Step 4: Convert the setting of active elements to Primary Amp values

Step 5: For each Ai block, find the maximum Primary Amp value of elements in that block (See e.g.).

Step 6: Find the minimum of the Primary Amp values found in Step 5

within all blocks (See e.g.).

Results


Relay settings need to be prepared for automation

Compliance and general reports can be automatically generated form Relay Setting repositories

Greatly free up time & effort on engineering resources

Modeling of short circuit software can be automated

Enables large scale analysis and studies such as Wide Area Coordination
