CYMDIST reporting facilities allow to fully define the analyses results into web reports. CYMDIST includes a variety of report templates for all types of analyses. You can combine any reports, and create new ones, utilize any CYMDIST variable and created your own mathematical expressions using any of those variables, which further extends the reporting possible with CYMDIST.

Advanced Project Manager: Supports the collaborative and detailed preparation of a project that consists in modifications to the network with related simulations.

Network Forecaster: To view, modify and create time-dependent projects (using the CYME Advanced Project Manager) consisting in modifications to the network such as the addition of any load at a given date, change/replacement of power transformers within a substation, a rephasing/reconductoring project, network switching or reconfiguration, etc.

Reliability Assessment: Provides a framework within which predictive and historical reliability assessment scenarios are run and the impacts of the related investment such as DA (Distribution Automation) can be evaluated and understood.

Energy Profile Manager: To perform time range analysis based on a combination of historical consumption patterns and real-time monitoring.

Transient Stability Analysis CYMSTAB: To simulate the dynamic behavior of distribution systems with distributed generation under various transient events (fault application/clearing, large motor starting, disconnection of co-generation units, islanding, etc.)

Harmonic Analysis CYMHARMO: To perform harmonic penetration analysis in electric power systems. It features single phase and full three-phase modeling capabilities and includes a large library of pre-defined models for network equipment and harmonic current sources. The Frequency scan capability included in this module is also available as an independent module.

Long-Term Dynamics Analysis: Allows power engineers to properly assess the impact of Distributed Energy Resources integration and to better understand related technical issues such as var control and voltage regulation.

Arc Flash Hazards Analysis: To analyze and promote the electrical safety for employees working on or near electrical equipment. It computes the necessary parameters required to assess the risk level and adopt the adequate safety procedures.

Dynamic Motor Starting Analysis: To simulate the starting of an induction motor or of a synchronous motor and obtain graphs of the results as a function of time or speed.

Load Flow Contingency (N-p): To assist in power flow related static contingency analysis. To create contingency events and single- or multiple-outage scenarios and compare to a base case.

Voltage Stability: To assess the ability of a power system to maintain stable voltages under different contingencies and loading conditions.

Embedded Protective Device Coordination: While the CYMTCC software is a stand-alone application, its installation with CYME or CYMDIST allows the user to access coordination functions and thus perform directly from the CYMDIST or the CYME interface analyses requiring protection data and design coordination schemes on a single platform.

Switching Optimization: Assists in determining the optimal feeder configuration that will minimize losses, improve the voltage profile and balance the load between feeders.

Single Contingency with Restoration: To study the impact of single forced or planned outages on the electrical distribution system and find the optimal switching plan to restore electrical power to priority customers and to recover the maximum possible load in the affected areas.

Enhanced Substation Modeling: To model all the major components of the distribution substation and any sub-network such as the detailed modeling of an industrial facility.

Secondary Grid Network Analysis: Allows the power flow and short circuit analyses of heavily meshed secondary network distribution systems for any voltage level.

Geographic Overlay: To display raster or vector map images (geographical land-base such as DWG, DXF, SHP, etc) as layers directly underneath the electrical model.

CYMDIST Gateway: CYMDIST Gateway is the CYME solution for the creation and maintenance of the CYMDIST distribution network data model. The connectivity network extracted from the GIS is accurate, electrically complete, with actual loads and switch status; and this network model can be updated easily.

CYMTCC: addresses Time Over-Current protection for Industrial, Commercial and Distribution Power systems. Features a direct interface to CYMDIST to verify the coordination of protective devices, the maximum permitted operating time («Reach») and the maximum permitted continuous load current.
