A software solution for the specification of energy systems

ARDANS

MODSARUS® is a plugin for Enterprise Architect (a commercial UML tool by Sparx Systems) that brings a model-based approach to the specification of interoperable, vendor-independent smart energy systems.
It supports the implementation of IEC standards (e.g. IEC 61850, CIM) enabling utilities to specify business processes, digital protection automation and control systems, and data exchanges.

Developed by utilities (EDF and Enedis), MODSARUS® is structured around several functional modules: MODSARUS-BAP (Basic Application Profiles), MODSARUS-Use Case, and MODSARUS Data Flow.

ARDANS

MODSARUS® is developed by Ardans and EDF for the utility sector and provide the tools implement IEC standards used in the engineering of modern energy infrastructures.

Ardans is a technology company specialized in knowledge management and model-driven engineering. It develops advanced software modules and created this extension for Sparx Systems Enterprise Architect, enabling structured modeling and automation of engineering processes. Ardans supports organizations in capitalizing, structuring, and sharing complex technical knowledge. Its solutions are widely used in systems engineering, energy infrastructure, and industrial digitalization.

Ardans is also responsible for the commercialization of solutions and first-level technical support for users.

Numerous applications

Designed for the engineering and specification of complex digital control and automation systems used in modern electrical infrastructures, MODSARUS® supports a model-based engineering approach for describing operational processes, system interactions and data exchanges within power system architectures, aligned with the standards of the IEC (e.g. IEC 61850, CIM series).

Digital substation automation

Protection, automation, control and monitoring systems within transmission and distribution substations

Smart grid architecture engineering

From metering, substations, and field equipment to control centers, maintenance and market systems, across the entire power system architecture

Distributed Energy Resources

Power system control of renewable energy systems and distributed generation
