PROTECTION & CONTROL

Project Highlights

NS1 & NS2 Transmission and Distribution Stations - CYNOG/TRES PLACIO


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. At TP added large gas compressor (13.8kV); provided substation 69/13.8kV protective relay design and settings; interconnection protective relay design of the substation to the South Texas Electric Coop.




Eastern Band of Cherokee Indians Reservation - EBCI


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.




Distribution Substations Scheme 9 Double Bus Outage Scheme Upgrades at 22 Substations - FPL


Distribution station scheme 9 DBOS (Double Bus Outage Scheme) consists of 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.




Various Substations - RTUs & SCADA


Replace or upgrade RTUs for the SCADA in both transmission and distribution substations. This includes the interface to Substation Communications Processors for direct communication to Protective Relays and other IEDs in the substation control room and out in the switchyard, typically with Fiber or RS485 connections.




MPLS Projects - Over 200 Substations Communication Network's Upgrade - FPL


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 communication provider’s protection tariffs involving GPR studies and High Voltage Isolation.




Various Substations - Scheme 8 DBOS - FPL, FL


Engineer upgrade to Scheme 8 DBOS differential protection in a cabinet where no space was available in the control room. Where space is available in the control room, then panel replacements.




Communication Network/SCADA/AGC Systems


Design, engineer and installation of the new Automatic Generator Control and SCADA system along with SONet communication network system using latest smart technologies.




Smart Grid Substation Upgrades - FPL, FL


Engineer, Construct and Commission upgrades at 256 substations communication, protection, automation and control systems. This included replacement of electromechanical protection relays with IED microprocessor based relays and fiber optic communications; reclosing controls modifications; Installed or modified the three types of Novatech Substation Communications Processors used for interrogation of new and existing IEDS for direct access into SCADA data repository.
