Addressing Critical Needs in the Electricity Industry

The electricity industry continues to undergo fundamental changes, which are shaping how engineering work is performed and energy services are provided. Low load growth, over-capacity, and future market uncertainty are creating pressures on the availability of capital and the reduction of operating costs to address issues of aging infrastructure. As electrical utilities are looking to replace and refurbish assets, the need to perform effective condition assessment, risk management activities, and strategic asset management planning arises.

These concerns are amplified by an increasing loss of internal technical expertise. As senior engineers retire and new engineers are brought in, the need to retain institutional memory and provide training guidance becomes ever more critical.

As electrical utilities are forced to upgrade and replace their aging infrastructure, many experience challenges in keeping pace with the flood of emerging technologies entering the market. It is both time consuming and capital intensive to find, test, and evaluate these technologies, but choosing the wrong one can lead to performance and financial consequences.

Finally, considering high energy demands along with increasing pressure to reduce greenhouse gas emissions and mitigate the effects of extreme weather events, the electric utility sector is faced with the unique challenge of providing energy services which are both cleaner and more reliable. Advancements in sustainability for all will require innovative approaches and rethinking business as usual.

PROGRAMS

Group Overview

Station Equipment Asset Management

The mission of the Station Equipment Asset Management Program (SEAM) is to disseminate the shared experiences and lessons learned regarding the life cycle management of station assets, which includes issues like purchas-ing (specifications, quality control, etc.), designing, installing, commissioning, maintaining, and operating the assets, as well as the disposal and planning for future changes/trends in the utility industry. The group assists participat-ing utilities in maximizing the safety, reliability, and efficiency of their station assets while minimizing costs and complying with applicable regulations, laws, and industry standards in order to produce the required reporting to applicable authorities.

2017 Spring Industry Conference: Innovations in Developing Stations of the FutureBuilding on the success of the 2016 conference, CEATI’s Station Equipment Asset Management Interest Group (SEAM) participants further explored areas of innovation in topics related to the development of future stations and ongoing maintenance. Technological developments in information technology, automation, and design improvements raise exciting possibilities and opportunities for a reconfigured electrical grid, enabling more effective monitoring and maintenance techniques while ensuring the reliability of supply, the sustainability of operations, and the affordabil-ity of electric service for customers. To enable smarter, more efficient, and cost-effective operation of station facil-ities, new station designs must now consider interoperability and monitoring capability to fully utilize these new technologies and associated telecommunications, information technology, security systems, and infrastructure.

Transmission Line Infrared Inspection Guide

Infrared inspections are used to identify anomalies and confirm the electrical integrity of transmission lines. Inspections are typically performed on all line hardware, conductor, shield wire/OPGW, insulators, splicers, spacers, dampers, bonding, grounding, etc. While many transmission companies commonly use infrared inspections to complement their other inspection programs, a best-practice infrared inspection guide does not exist. This project is intended to provide a guide for the effective use and application of infrared technology for transmission line inspection.

Transmission Line Reliability and Component

Performance Measures and Their Application

This initiative will develop a set of reliability measures for monitoring, recording, and assessing the perfor-mance of transmission lines at 3 levels: 1) the transmis-sion system level, 2) the transmission line level, and 3) the component level. This will allow utilities to effec-tively manage the reliability performance of transmis-sion line assets, and to establish a format for collecting line component failure and outage information to be used in calculating these measures. This project will enable personnel looking after transmission lines to better understand how failure of individual compo-nents impacts overall transmission line and transmis-sion system unreliability, and will allow the analysis of “what if” scenarios in deciding where investments should go to improve system reliability performance and to estimate future performance.

Improvements to Fall of Potential Ground Testing

The goal is to investigate the proximity correction method for measuring station ground impedance and to compare its efficiency and accuracy relative to the existing method proposed by IEEE STD 81. This review of methods for measuring station ground impedance will be relevant to generating stations, HV transformer stations, distribution stations, and distributed grounding systems that have solar or wind power developments.

Rating and Placement of Working Grounds

Existing standards on working grounds define current ratings and provide graphs for estimating touch potentials for different working grounds placements to define a safe working zone. Utilities need simple, quantitative tools to calculate the stresses seen by working grounds and by staff when X/R ratios differ from rated values, particularly when applied away from stations along lines and when orientations relative to source conductors differ from pictures in the standards. Additionally, utilities need tools to review ancillary topics such as capacitively and magnetically coupled voltages and currents that affect voltage testing and arcing when installing and removing working grounds. Tools to calculate step and touch voltages and currents when working around vehicles may also prove useful to utilities. The tools for calculation provided through this project for working grounds can be applied to air insulated transformer, distribution, and generating stations at all voltage levels.

Step and Touch Coordination During Substation Expansion

This project will provide an analytical review of the step and touch potentials resulting during various construction and maintenance activities of substation expansion. The study objectives include: 1) Review the hazards resulting from existing construction procedures; 2) Explore a wide range of barriers and procedures to reduce step and touch potentials; and 3) Quantify the efficiency and hazard reduction offered by differing mitigation methods.

Infrastructure Protection & SecurityGroup OverviewThe Infrastructure Protection & Security Interest Group (IPSIG) is an international technical forum for utility engineers, operators, and both physical and cyber security experts in the fields of Power Generation, Transmission, and Distribution. This group facilitates the sharing of experiences among utilities and develops solutions to better secure utility assets from physical and cyber threats, while also filling a niche area that helps cyber and physical security specialists understand each other’s concerns and remedies.

Cyber Security: Program activities aim to evaluate cybersecurity standards and frameworks for communication and control networks, risk management, and regulatory compliance.Physical Security: Program activities aim to enhance the design and functioning of security operations for dams and powerhouses, substations, transmission/distribution assets, and RoWs.

Physical Security Maturity MatrixIPSIG’s participating utilities have recognized that physical and cyber security play an important role in electrical utility management and operations. The increasingly prevalent and severe physical and cyber security incidents affect organizations of all types. This demonstrates the need for electric utilities and related companies to continually evaluate and improve upon their security programs and procedures.

The Physical Security Maturity Matrix identifies the key attributes that should be addressed in order to create and maintain an effective physical security program within an electric utility. The matrix will help electricity organizations benchmark their security programs against others in the industry, allowing them the relative effectiveness of these programs and to justify enhancements or modifications. Alternatively, utilities can perform self-evaluations in order to identify weaknesses and areas for improvement.

2017 Highlighted ProjectKey Management

This project identifies the key management approaches currently being employed by IPSIG members and develops recommendations for “best practices” that can be applied to the full range of access control needs of electric utilities. Emphasis is placed on the integration of all tools (phys-ical and cyber) to effectively manage access control, which includes key fobs, cascading locks, and double authentication (depending on security needs).

Don Burlack (CISSP, CISM) has over 37 years of experience working within the telecommunications and electricity utility industries, with almost 30 of those directed towards computer science and cyber security. At SaskTel, he became the Senior Systems Security Director; at SaskPower, he held the position of Supervisor - Cyber Security; within the Technological Crimes Section of the RCMP he served as an Auxiliary Constable; and he has lead ethical hacking classes as an instructor for EC-Council.

The program provides vegetation managers with a cost-effective vehicle to share experiences and to address issues pertinent to their day-to-day operations, maintenance, and planning.

4th Annual Vegetation

Management Conference

The effective management of vegetation on transmission and distribution corridors is essential for providing a reliable supply of electricity and for ensuring public and worker safety. The focus of the 4th Annual Conference was on the various technologies, techniques, and equipment that are being developed or are currently available to Vegetation Managers.

Themes

• Public & Social Issues • Techniques & Products• Program Management

Vegetation Management Cost Benefit of Herbicide Use

This study compares the cost of maintaining vegetation on electric transmission right of way (ROW) corridors with and without the use of herbicides. Three case studies were used to compare the cost of Integrated Vegetation Management (IVM), which includes the use of herbicides to control incompatible trees to simply maintaining ROW vegetation by repeated cutting without the use of herbicides. Least cost economic analysis methods were used to determine the present value cost of each vegetation maintenance prescription over a 20-year evaluation period. This project convincingly demonstrates that a vegetation management strategy based on the principles of IVM (including the use of herbicides) is less costly than a strategy that does not use herbicides and relies simply on repeated mechanical and manual treatments.

Control of Weeds in Electrical Facilities such as Substations, Switchyards, Capacitor Stations, and Cable

Termination Sites

The purpose of this project is to develop two herbicide programs: one that utilizes products available in Canada, and one for the United States. These programs must be designed to reduce the development of resistance and should also include strategies to reduce reliance on herbicides, such as preventative measures and non-herbicide techniques.

Powerline Vegetation Management Best Practices within Boreal Forest Caribou Regions

Electrical utilities are expected to develop and maintain powerline RoWs in a manner that avoids or reduces impacts on caribou and caribou habitats. This project will help utilities identify and implement the most effective programs for boreal forest caribou regions. The document will specifically help justify the selection and, conversely, the avoidance of various mitigation techniques, management practices, and generally accepted industry practices in caribou regions. Conversely, electrical utilities can avoid being pressured into implementing those mitigations that are deemed to be non-effective and of no value.
