ECF ENGINEERING
CONSULTANTS
ECF was contracted to perform the substation and protection & control engineering for a new 500/230kV transmission substation with two 500kV (4000A) bays, four (4) 230kV bays and four (4) single phase 500/230kV, 500MVA autotransformers, where one will be sued in the spare position. The Quarry substation layout accommodates an expansion plan for two (2) additional 500kV lines, a second autotransformer and additional 230kV lines, while also allowing space for future tertiaryshunt reactors and 230kV capacitor banks.
Expanded the substation and constructed a new 230kV switchyard with two breaker and half bays and Capacitor Bank. The expansion included the space for future 115kV bay. Perform grounding study. The 230kV ground grid and structures should be built for 63kA. Add lightning shielding as required. Performed Lighting (illumination) Study for yard, which resulted in installing perimeter & yard lighting, and reliability cameras.
New 230/115kV Substation - Construct one (1) 230kV bay rated for 2000 amps with one (1) line pull-off structure and connections from the West 230kV and 115kV buses to the autotransformer and three(3) 115kV bays rated for 2000 amps with five (5) line pull-off structures as shown in figure A. Install station lightning system, cameras and card reader.
Perimeter LED's & Security Camera Perform Illumination Study for Sugar site including new 500kV Yard Expansion and replacement of all existing HPSV lighting with LED. Update all relevant substation prints to incorporate the cameras and security related equipment including but not limited to card readers and gate motor operators as stipulated by Corporate Security as well as all required conduits, grounding, circuits, and any other required details.
Install 230-138kV, 560MVA AutoTX to East Bus. Replace existing East and West Buses to meet 63KA fault current with 5” Bus and Extra high strength insulators. This included replacing structures and foundations. Installed new 230kV Demag switch and 138kV bus switch for East Bus. Removed 230kV String bus in 1A and replaced with 3000A double breaker bay equipment, including (2) 3000A breakers and (3) disconnect switches. Bay designed with 230kV Pull-off Tower with space for future line addition. Installed new secondary battery system inside existing house. Grounding study and Lightning Shielding study performed for the entire yard.
Replace distribution feeder breakers and bus tie breakers; add new feeder positions including breakers, switches, regulators, fbcts, etc. both in “old pipe rack” stations as well as in “newer moduflex” stations. During transformer additions or increase capacity projects, revise breaker load balancing for bay assignments to a given transformer and revise autorestoration & fault bus schemes as required. Evaluate foundations and oil pit containment as required. During increase ampacity projects, modify bus and switches to accommodate new ratings.
ECF was contracted to perform the substation & protection & control engineering for a new 230/138kV transmission substation within the existing 138/69kV substation. This new portion of the station consisted of two (2) 230kV breaker and a half bays rated for 3000 amps, autotransformer & three (3) 138kV bays rated at 3000 amps which connected to the existing 138kV bus in the station.
ECF was contracted to perform the substation and protection & controls engineering for a new 26kV switching station. The design consisted of one (1) regulator and four (4) feeder breakers. ECF partnered with subcontractors to provide civil/structural design, surveying, and geotechnical analysis as part of the scope of the project.
ECF was contracted to perform the substation & protection & controls engineering for a new solar 230/34.5kV substation. The design consisted of one (1) 85MVA GSU, two (2) high side transmission line breakers, one (1) GSU high side 230kV breaker and one (1) 34.5kV low side breaker connected to the solar farm collector bus.
ECF was contracted in a Design-Build arrangement to design and install upgrades at approximately 245 transmission substations across the state of Florida. The scope of work included engineering, installation, and testing/commissioning of upgrades to electrical and communication systems for various functions in the substations' control schemes. Each station was unique in size and scope. ECF deployed multiple construction crews across the state, while performing all engineering from its West Palm Beach Headquarters to complete the project safely and on schedule. ECF self-performed all project management, engineering design, construction management, and material coordination through our client's systems.
