E-Vlivy 3: DS status analysis

Notice: This system is nowadays supported for existing applications only. DNCalc which is developed on E-Vlivy basis and enhances its features is intended for new project.


New generation of E-Vlivy program  refers to previous successfulversions and allows full-scale analysis large, tied and shunt power networks (LV, MV and HV).  


E-Vlivy 3 application window User interface of E-Vlivy 3


Implemented functions allows now only standard calculations but also aims for power quality, connectibility of resources into distribution networks, Smart Grids and other advanced functions which provide the solid tool for full-scale analysis related to operation and development of distribution networks to the user. 

Implemented methods comply with series of legislative and standard documents, in example: PPDS, CSN IEC 1000-2-2, CSN EN 61000-3-2, CSN EN 50160ed. 3, CSN EN 60909-0, series PNE 33 3430, Directives of D-A-CH-CZ and other. 

 E-Vlivy 3 - architecture

Basic structure of program functions  


E-Vlivy program provides environment with broad spectrum of tools for modelling and managing of large scale power network diagram and allows network calculation, fault conditions and active and reactive power loss analysis.

Additional functions are included in modules focusing on specific issues of distribution systems modelling and assesment. 



Connectivity Module

This module provides elements and functions to connectivity evaluation of generations and loads connected to distribution system or local distribution system in compliance with valid legislation. Connectivity Module enhances basic module with following elements and analysis: 



Power Quality Module

Power Quality Module focuses on full coverage of analysis associated with evaluation of load and generation impacts on power quality. These analysis include both the existing conditions and future situation resulting from technology changes, connection of new loads, network modifications etc. Power Quality Module enhances Basic Modules with following elements and analysis:



Three-phase Calculation Module

Three-phase Calculation Module enhances the basic calculations for accurate multi-line analysis of network status during operation and connection and disconnection of symmetrical and non-symmetrical equipment under normal and faulty newtork conditions. Benefits of this module analysis lay mainly in description of conditions of each conductor in simulated power network. This is necessary in example for accurate analysis of connection of several single-phase plants to LV networks. The Three-phase Module enhance the Basic Module with following elements and analysis: 



Online Calculation Module

This Module includes online calculaitons. The interface specificaton depends always on data source. Calculating software allows import of real data from external systems such as SCADA, systems for power network measurements recording and evaluating, etc. 


E-Vlivy program supports the Windows XP, Windows 7 and other operating systems.
