Program 14

Program 14 projects focus on the following technical areas: Engineering Analysis Software, Engineering Guidelines, Equipment Testing/Evaluation, Industry Perspectives / White Papers, Operational Efficiency, Smart Grid, System Protection, Workforce Training

Project 4 - Surge Protection of Electronically-Controlled Devices Installed in Distribution Systems

The scope of this project includes a survey/literature review phase and an analytical phase.

The key issues the literature review and survey addresses are:

• Analysis and examples of failed electronic controls

• Explanation of grounding principals

• Explanation of surge mitigation on the device and within the control.

• Examination of placement of the station service transformer

• Examples of utilities that have used grounded electronic controls and have had good results.

• Discussion of effectiveness and cost of grounding methods (where data permits)

After the literature review and survey, simulations will be conducted to investigate the susceptibility of various commonly used configurations and to assess and verify the effectiveness of mitigation strategies identified during the utility survey and/or literature search.

Project 5 - Cable Pulling Assistant Updates

This project focuses to update the CPA program to include the following enhancements:

Core Programming Updates

• Modify the existing 3-D visualization to show manholes

• Allow the user to choose different types of conduit for each section (High priority)

Interface Changes and Other Minor Updates

Several issues and suggestions have been reported by users since Version 3.25 was released. These include some changes to the CPA interface as well as some other minor updates that would improve the user experience. In addition, some bugs that have been identified by users that were not addressed in subsequent Programs have been included.

Project 6 - Best Practices for Integration of Utility Communications

The scope of this effort focuses on the evolution from an environment where a utility communications system was hard coupled to the supported application and the data source is coupled to the data consumer to one where all of these elements may evolve independently.

Two main topics currently being considered:

• Maximizing the use of existing and future communications infrastructure - This topic includes utility experiences in migration of legacy applications to newer communications technology, the factors influencing the choice between separate or converged communications infrastructure moving forward, and strategies which utilities have employed when opting for converging multiple applications onto a single communications system.

• Access to power system related data outside the traditional system boundary - This topic includes utility experiences related to the need for more and more applications to access power system related data including the challenges associated with data formats and accessibility. How utilities are dealing with cyber security aspects and strategies moving forward for a single data source (e.g. power system IED) to support multiple applications.

Possible applications to be considered within this effort include:

• Power System Protection

• Distribution Automation (DA)

• Substation Automation (SA)

• Demand Response (DR)

• Advanced Metering Infrastructure (AMI)

• Distribution Management System (DMS)

• Outage Management System (OMS)

• State Estimation

• Automatic Generation Control (AGC)

• Supervisory Control and Data Acquisition (SCADA)

• Power Quality (PQ)

• Asset Monitoring

• Wide Area Monitoring, Protection, and Control (WAMPAC)

• Distributed Energy Resources (DER)

• Electric Vehicle (EV)

Project 7 - Survey of Best Practices for Copper

The scope of this project includes a literature search, survey, and whitepaper.

The literature review includes:

• Theft deterrents

• Law enforcement options

• Alternate materials

The survey covers the following:

• Theft deterrents

• Low enforcement options

• Alternate materials

• Approximate cost and/or number of incidents of copper theft

• Successes - approximate costs and theft reductions from successful measures implemented

• Failures – measures attempted that were not successful and reason for failure

The result of this project will be a whitepaper report that summarizes findings and recommendations for deterring copper theft on overhead and underground equipment for distribution feeders and substations.

Project 8 - Motor problems Resolution and Avoidance – Update CRN Publication

This project follows the scope and organization of the existing report except a couple of new sections will be added to expand beyond motors to include electronic power converters (sometimes called “Drives”). The case studies will be expanded to include illustrations of how drives affect motors.

This project has been scoped to identify and revise the contents of the manual according to the latest industry standards, practices, and guidelines. The revision will include updates and/or additions based on new equipment and changes in equipment and technology since the manual was first published, including information on:

• Impact of new applications such as CVR, smart technologies

• Low voltage issues

• Unbalance voltage issues
