Connectivity projects related to the transmission system backbone require specific simulations to identify and address potential problems, as well as managing system performance and reliability. Eaton’s CYME transmission system software applications support modeling and analysis of medium-scale projects that incorporate decentralized generation.

CYME for Power Transmission and Industrial Power Systems is a comprehensive suite of integrated software programs that perform the simulations and analyses of transmission or industrial electrical systems as needed by the electrical engineers.

The CYME Power Flow software is the power flow analysis module of the CYME power engineering software for the analysis of three-phase electric power networks. It is equipped with powerful analytical options and alternative solution techniques. A wide selection of network equipment and controllers is supported by a built-in database that contains industry standard equipment characteristics. Every type of equipment features more than one modeling possibility depending on the purpose and extent of the simulation to be conducted.

Cyme offers both graphical and tabular data entry modes, user-preferred single-line diagram drawing options and sophisticated facilities for reporting, plotting and customizing the simulation reports. Deploying Cyme brings significant advantages in performing the planning, design and problem-solving activities related to the assessment, improvement and maintenance of electrical power systems. Cyme is directly applicable to both utility-type and industrial three-phase electric power systems.
