The Secondary Networks module is an add-on to the CYME Power Engineering Analysis Software. It is designed to perform the power flow and short circuit analysis of heavily meshed secondary network distribution systems for any voltage level.

The Secondary Networks module enables the user to build the secondary grid by including the complete vaults with their transformers and protective devices, the secondary lines or cables, as well as the distribution transformers.

It uses the graphic editor of CYME to model the secondary network and display the results of the power flow and short circuit simulations on the one line diagram. Any portion of the system can be selectively visualized in detail and system-wide results can be viewed for any type of simulation.

The module also includes a comprehensive suite of presentation tools for selective visualization and effective management of large data sets, like spreadsheets, rapid graphics and a multitude of context-dependent reporting facilities such as:

• Full voltage drop and short circuit reports
• Overloaded conductors and devices
• Abnormal Conditions
• And others

The CYME Substations and Sub-Network Analysis module and the Secondary Network Analysis module greatly enhance the capability of our CYME power system analysis software by including, in addition to the primary feeders, the substation detailed representation and the secondary grids all the way down to the customer’s transformers.
