Project Description

This project set focuses on

– Identifying,

– Documenting, and

– Sharing Practices

By identifying better

methods, utilities can

improve

– Efficiency

– Reliability

– Safety


Practices ResearchFocus Areas

Underground Systems Overhead Systems


Underground Systems

Focus Area - Network Systems

Prevalent design

in US for urban

centers

Redundancy

Higher Cost

High Reliability

Source: Con Edison

2016 Focus


Underground Systems

Network Systems

Challenges

– Aging infrastructure

– Serves high visibility customers

– For most utilities, represents

small % of overall infrastructure

– Limited employees with subject

knowledge / knowledge loss

– In some cases, high reliability

has resulted in limited

maintenance

– Environmental issues

– Increasing failures, often

“spectacular”

2016 Focus


Overhead SystemsFocus Area – Distribution Automation Specialists

DA prevalent and growing

Managing these devices is

challenging

– Rapid change in technology

– Continued need for compatibility

and integration

Managing requires coordination of

resources with varied skill sets

Need to identify, document and share

practices

Distribution Systems Practices

(P180.019 & P180.020)

• Overall research objective

Identify, document and share leading industry practices

• What are we doing in 2016?

Identifying and documenting leading industry functional practices in urban underground systems.

Investigating issues and practices for distribution automation device management including activities such as designing, provisioning, installing and commissioning, testing, maintaining, operating and troubleshooting.

• Why is it valuable?

Participants can compare and validate their current practices for

managing systems against those of peer companies to identify

optimum approaches for application at their company. By identifying

better methods, utilities can improve efficiency, reliability, and safety.
