At PROTASIS, advanced engineering expertise is combined with a carefully selected ecosystem of industry-leading software platforms to address the growing complexity of transmission, distribution and industrial power systems. Each tool is chosen based on strict technical criteria, including accuracy, compliance with international standards, proven performance in diverse grid environments and the ability to respond to real-world operational challenges.
Scalability and interoperability are also key considerations, ensuring that power system studies remain robust as projects evolve and integrate seamlessly with utility frameworks and third-party systems.
Addressing complex grid challenges with advanced simulation tools
To support the full spectrum of modern power system studies, PROTASIS has integrated a comprehensive portfolio of specialized software solutions, covering transmission planning, electromagnetic transient analysis, industrial facilities and substation engineering.
Transmission and distribution system studies
For transmission planning and operational analysis, PROTASIS utilizes PSS®E by Siemens, a widely adopted platform for load flow, short-circuit and dynamic stability studies in complex, interconnected networks.
Complementing this capability, PowerFactory by DIgSILENT is deployed for detailed network modeling, protection analysis and system optimization across both transmission and distribution grids.
PROTASIS also acts as the official DIgSILENT representative in Greece, providing technical expertise and end-to-end support to PowerFactory users across the energy sector.
For detailed distribution system analysis and planning, CYME by Eaton is used to perform load flow, fault studies and network expansion assessments for utility and industrial distribution networks.
Electromagnetic transient and power electronics analysis
With increasing penetration of power electronics and inverter-based resources, understanding fast transient phenomena has become essential. For this purpose, PROTASIS deploys EMTP® by EMTP Alliance, enabling detailed time-domain simulations of switching events, control interactions and complex network configurations.
In parallel, PSCAD™ by Manitoba Hydro International provides a high-fidelity environment for modeling power electronic converters, advanced control systems and transient phenomena that play a critical role in renewable energy integration and grid stability.
Industrial facilities and critical infrastructure
Power system studies for industrial facilities, infrastructure projects and data centers are performed using ETAP® by Operation Technology, a fully integrated platform tailored to complex installations where reliability, operational continuity and safety are paramount.
Protection coordination studies across all sectors are supported by OneLiner™ by ASPEN, enabling power flow and short-circuit analysis, relay setting calculations, protection audits and wide-area coordination assessments.
Substation engineering and grounding design
For high-voltage substation design, primtech 3D supports advanced 3D modeling, layout optimization and detailed documentation for both air-insulated and gas-insulated substations.
Substation grounding grid design and analysis is performed using CYMGRD by Eaton, enabling engineers to design new grounding systems and reinforce existing installations in line with stringent safety and performance requirements.
Real-time simulation and Hardware-in-the-Loop testing
To complement simulations and traditional planning and operation studies, PROTASIS integrates RSCAD® FX by RTDS Technologies, a comprehensive real-time simulation platform that runs directly on the user’s PC. Through its intuitive graphical interface, engineers can configure, execute, and analyze complex power system models while interacting with the simulation in real time.
The platform enables both Controller Hardware-in-the-Loop (CHIL) and Power Hardware-in-the-Loop (PHIL) testing, allowing utilities and manufacturers to validate protection, control, automation schemes and several other component-based applications (EVs, BESS, power electronic devices) under realistic operating conditions.
With extensive libraries of power system components and scripting capabilities for automated testing, RSCAD® FX bridges the gap between theoretical models and practical implementation, ensuring designs are operationally robust, safe, and future-ready.
From advanced tools to actionable engineering decisions
The value of sophisticated software platforms ultimately depends on the expertise of the engineers applying them. PROTASIS’ technical teams are thoroughly trained, ensuring that each tool is used to its full potential.
Through custom model development, scenario-based simulations and adherence to established engineering best practices, power system studies deliver results that support informed decision-making, risk mitigation and long-term asset performance.
By combining deep engineering know-how with a best-in-class software ecosystem, PROTASIS supports projects ranging from grid reinforcement and renewable energy integration to protection and control studies for critical infrastructure.
This integrated approach enables stakeholders across the energy sector to navigate today’s technical challenges while preparing networks and facilities for a more resilient, flexible and future-ready power system.
