Project sheet A

Photovoltaic solar generation plants

Context

Photovoltaic plant connected to the National Interconnected Electric System.

Challenge

Interconnect inverters, weather station, control house and evacuation substation across extensive terrain, with high electromagnetic interference and exposure to lightning.

Scope

Single-mode fiber optic backbone in a ring topology between transformer stations
Underground ducting and aerial installation of ADSS cable
Fusion splices and optical distribution frames
Industrial switches with extended temperature range
Backup radio link to the control center
Integration with the plant’s SCADA platform

Outcome

Redundant communication between generation and the control center, with continuous telemetry and availability verified in acceptance tests.

Project sheet B

Mining operations

Context

Mining operation with moving work fronts, a processing plant and a camp.

Challenge

Keep field personnel, mobile equipment and the control center in contact on changing terrain, where fixed infrastructure cannot always keep up with the advance of the operation.

Scope

Point-to-point and point-to-multipoint radio links between the plant, the pit and the camp
UHF radio system with repeater stations and a coverage study
Radio-over-IP gateways that integrate the repeaters with the data network and the dispatch console
Self-supporting and guyed towers with a grounding system and lightning protection
Fiber optics in the plant area

Outcome

A single voice system across work fronts, the plant and the control room, with coverage verified in the field.

Project sheet C

Electrical substations

Context

Transmission or distribution substation and its link to the control center.

Challenge

Carry protection, control and telemetry data in a high-voltage environment, where copper is not viable because of electromagnetic interference and ground potential rise.

Scope

OPGW fiber optic interconnection over transmission lines and interface with ADSS cable
Splice closures and optical distribution frames in the control house
Indoor fiber between switchgear bays, panels and the control room
Radio link as an alternate path
Integration with substation automation protocols
Radio over IP to connect yard personnel with the control center

Outcome

Link immune to electromagnetic interference between the substation and the control center, with an independent alternate path.

Cross-cutting technical scope.

The working method we apply on every project, from up-front engineering to closeout.

Up-front engineering

Site survey and assessment of existing infrastructure
Line-of-sight study and terrain profile for each radio link
Link budget calculation with a defined fade margin
Radio coverage study and frequency plan
Detailed engineering: fiber routes, tower locations, communications single-line diagrams

Fiber optic installation

ADSS aerial cable laying, OPGW interface and underground ducting
Fusion splices, splice closures, optical distribution frames and organizers
Bidirectional OTDR certification of each link, with insertion loss and return loss measurement
Delivery of the certification traces as part of the project file

Radio link and radio installation

Tower assembly, antenna installation and alignment
Grounding system and lightning protection
Equipment configuration and link capacity, latency and stability tests
Installation of UHF repeaters, radio-over-IP gateways and dispatch console
Coverage testing along a route in the field

Industrial environment conditions

Industrial-temperature-rated equipment and cabinets with a protection rating suited to the environment
DC power backup and uninterruptible power systems
Electromagnetic compatibility considerations in high-voltage yards
Protection against dust, humidity and salt air depending on the location

Safety and compliance

Task-level risk analysis and work permits coordinated with the client
Compliance with site safety procedures, including lockout and tagout at energized facilities

Project closeout

On-site acceptance tests with the client
As-built drawings and documentation
Training for operations personnel
Warranty and preventive maintenance plan
