Power Automation Services

We offer engineering, systems integration, and field support solutions for automation in electrical substations and power distribution systems.
As part of power automation services, we provide SCADA integration services and complete value engineering to maximize the use of data available from your smart assets and overall improvement of your system's operation, for both the present and the future. Our solutions and services cover low, medium, and high voltage systems.

Automation Engineering

• Systems engineering design, development, and configuration of IEDs, RTUs and Automation controllers for logic control schemes for different protection and automation functions within the substation and power distribution systems. (i.e. Automatic Transfer Schemes (ATS), Automatic Switching, Automatic Load Shedding, etc.)
• Consulting Services for evaluation and value engineering on power automation systems, power substations, network communications, and SCADA integration
• Human Machine Interface (HMI) design, development, and implementation for local substation and SCADA systems
• Automation communications network design and integration, including network topologies, media, and protocols
• Test and commissioning procedures

Systems Integration

• Integration of Protection relays, RTUs, SCADAs, and other related communication/automation platforms
• Engineering Access and event data retrieval from IEDs (Intelligent Electronic Devices)
• HMI programming and development, including configuration of historian and alarm archiving
• Functional & performance testing
• Factory Acceptance Testing (FAT)

Field Support

• On site installation and commissioning support
• Supervision of installation and testing
• Field testing of integration of IEDs
• Maintenance and support of systems delivered
• On site training and training materials

Design and Protection

Our focus is medium voltage protection design. We can deliver new system design or perform relay retrofits and system protection upgrade.
Our team of experienced engineers take conceptual power system protection ideas and turn them into implemented solution on the field. We present preliminary design and (explain the process from idea to realization/installation)
Our team is versatile in operating and programming equipment of manufacturers such as SEL, GE, Siemens, Basler, Beckwith, ABB, Schneider, among others.

Protection Engineering

• Protection systems design, specification and procurement
• Protective relay and component selection and specifications development
• Switchgear design, specification and procurement
• Development of protection philosophy for various applications, such as feeder distribution, medium voltage protection, transformer protection, and special protection schemes (i.e. load shedding schemes, fast transfer schemes, etc.)
• Development of AC/DC schematics and wiring diagrams
• Development of point to point wiring sheets with wire labels for field upgrades
• Project management
• Test and commissioning procedures

Event Analysis and Troubleshooting

• Evaluation and forensics of power system events
• Analysis of relay event waveforms and digital elements
• Set up of automated event collection and reporting platforms
• Ability to provide remote troubleshooting capabilities



 

Power System Studies

Our team of Professional Engineers provides fast and reliable turnaround for the various Power System Studies. Studies are completed in an industry leading software (e.g. ETAP, SKM, ASPEN, CYME, DesignBase, CDEGS, etc.) and per customer’s choice.

Protection Coordination Analysis

The study evaluates degree of overcurrent protection in the system and proposes relay/breaker setting to maximize selectivity in the system.
When required, study can be augmented by Relay Philosophy Document which specifies settings for other protection types (beyond overcurrent).

Short Circuit Analysis

The study verifies that all the equipment is properly sized for mechanical and thermal short circuit effects (includes breakers, switches, busbars, cables, etc.) under different operation scenarios in order to assess the maximum fault level.
The study complies with all the applicable ANSI / IEEE requirements.

Arc Flash Analysis

The study is based on the latest version of IEEE-1584 and NFPA-70E. It evaluates multiple network configurations in order to obtain the worst-case results.
Printing of arc flash stickers is included
Cable Ampacity Analysis
Cable Ampacity Analysis is based on Neher-McGrath method.
Calculated cable ampacity is based on all installation cases. This typically includes: cables in trenches, bores, duct-banks, cable crossings, parallel runs, cables on riser poles, etc.
Cables are modeled per manufacturer’s specifications. Generic cable models are not used.

Harmonic Analysis

Study verifies if harmonic levels (for both: current and voltage) exceed the recommendation given in IEEE-519 standard.
If the requirements are exceeded, study compares harmonic distortion indices with equipment withstand limits.
