Relay Protection and Control


Our TeamThe ECF group consists of a collection of highly qualified consultants in the area of utility relay protection & controls. We understand the increasing role that reliable communication plays in the area of safe and reliable protection & control of the power grid. With extensive experience in design and commissioning of relay systems, ECF offers the range of knowledge necessary to carry out and complete the project. Experience in this area includes both new and retrofit projects. When approaching retrofit projects ECF is very aware of the risks in working within the confines of an energized protection system and reflect that knowledge at all levels of the job from conceptual design through final commissioning. ECF's P&C design work covers projects of all types with the majority of work at 13 kV through 500kV stations. Typically the scope of work includes the complete design, from conceptual through detail. Many of these projects included outage planning, installation, and commissioning.

Relay protection and controls design is the largest single sector of ECF's business. This is mainly attributed to the successful performance of protective relay projects and the strength of ECF Power Delivery staff in this area. Also reflected is the importance customers place on this expertise. Currently there are six (6) senior staffs who have managed relay protection and controls groups with major investor owned utilities. No less impressive is the next level of staff that has extensive experience within protection and controls groups responsible for both T&D and generation functions. Currently ECF has senior level protection engineers with all totaled, over 150 hundred years of experience; yet have practical and innovative experience working with current-state technologies and products that have been introduced to the marketplace.

Some of the areas covered are:

• Supervisory Control & Data Acquisition Systems
• System automation and integration
• Controls and instrumentation
• Protective relaying design and testing
• PLC and OIT design and programming
• Power & lighting design
• Start-up & commissioning
• Substation Automation

ECF professionals have experience in designing, and implementing communications networks in the electric utility industry to meet the ever-increasing demand for communications capabilities in the power grid. This includes establishing secure communications connectivity for smart devices, SCADA monitoring and controls with distribution switching and capacitor bank points in the field. ECF has engineers that have worked in both the Substations/Protective Relaying teams as well as in IT-Telecom teams, and understand how to effectively communicate project goals in a language that either team will understand. ECF has been especially effective in facilitating discussions between the substation and IT-Telecom teams that occasionally do not have warm and friendly business relationships. This has resulted in win-win results with lasting positive benefits for the utility.



ECF professionals will work closely with clients' power engineers as well as the IT and Telecom teams as needed, to ensure and appropriate level of understanding of the data services and environmental needs of equipment installed in a substation. IEEE has standards and guidelines developed and in place to provide assistance in proliferating the understanding of the requirements to the necessary personnel, to assist in winning the support of professionals not traditionally familiar with the different needs found in a substation environment.

The deployment of Smart devices and communications networks will provide an even greater push toward moving traditionally data-center located equipment out to the edge of the network, closer to the user. ECF personnel have the experience to ensure that the overall system architecture and designs will be robust and secure enough to provide years of reliable service.

ECF personnel are well trained in the following Communications related areas:

• Communications system (fiber, RF, leased) architecture and planning, design, procurement, implementation
• IP (Local Area and Wide Area) Network Design and Implementation
• SONET System Architecture, Design, and Implementation
• Cyber Secure compliant systems design
• AC/DC Power Systems Design for Communications Networks
• Grounding and Bonding Design (Telcordia – certified grounding & bonding engineer on staff)
• Communications Network provisioning
• Fiber - inside and outside plant
• RF network design
• Commissioning & Testing

Utilizing a staff of experienced engineers and test technicians, ECF offers comprehensive commissioning and testing services. The team approach results in a high quality product that includes well-documented test results, drawings and reports. A highly experienced support staff of engineers makes ECF exceptionally qualified to solve complex problems, evaluate design issues, and offer timely solutions. ECF technicians and engineers are experienced working in the utility and industrial environment with safety being their primary priority during all activities. A continuously revised and reviewed safety program ensures safe work conditions for personnel.

Examples of projects our employees participated in or had direct relevant and lead technical experiences include the following:



CNYOG | NS1 230 /13.8 kV and NS2 138/13.8 kV Transmission and Distribution Substations
Engineered substation automation platforms for transmission and distribution substations. This project included networking substation IED's for SCADA, local annunciation, local Distributed Control System, protection functions and data acquisition local/remote to establish a full operational smart facility using state of art technology.
EBCI | Eastern Band of Cherokee Indians Reservation Communication Network
Worked in concert with the client to developing conceptual design of communication network for bring broadband network access to residential and business clients located on the Qualla Boundary, Graham County and Cherokee County communities.
FPL | Distribution Substations Scheme 9 double Bus Outage Scheme Upgrades at 22 Substations
Distribution station scheme 9 DBOS (Double Bus Outage Scheme) consists of a sub panel, which is integrated with existing scheme 9 overcurrent and differential panels to add oscillography, communications and enhanced automatic station restoration to the existing scheme 9. The DBOS panel consists of two SEL 751A relays with associated terminal blocks, test blocks, and wiring designed to be installed on a 19" relay rack. The panel is 16 rack units (28") tall.
FPL | Increase Station Capacities
Increase the capacities of existing distribution station by adding transformers with LMS systems and other associated supportive equipment (breakers, circuit switchers regulators, switches etc.).
FPL | MPLS Projects - Over 200 Substations Communication Network's upgrade
FPL data requirements in the substations are increasing. The existing substation SCADA data circuit technology has reached end-of-life and were upgraded to data rates up to 1.5MHz. The enhancement performed required additional infrastructure to be compliant to the communications provider's protection tariffs involving GPR studies and High Voltage Isolation.
FPL | Upgrade Substation Battery monitoring System at Over 100 Substation
Installation of IED type Battery Monitoring System as a part of FPL's Energy Smart Florida Project consist of but is not limited to the removal of the existing battery alarm module, the installation, assembly, termination, testing and commissioning of BA300 battery alarm monitor. This new system will automatic check and notify operations the status and health of the battery system.
