Power System Modelling
Using reputable Power System program to perform several types of analysis on balanced or unbalanced three-phase, two-phase and single-phase systems that are operated in radial, looped or meshed configurations. The base module includes per-phase voltage drop and power flow analysis, fault calculations (fault flows and fault voltages), protective device coordination, capacitor placement and sizing, load balancing, load allocation / estimation, predictive and historical reliability

analysis, contingency analysis (load restoration), switching (tie-points) optimization and more as described below.
Power System modelling, Simulation & Anaysis service is extremely powerful in performing "what-if" studies and it allows the creation and management of several project-scenarios, all related to the same base network. Each project consists of a set of modifications, which alter the data or the topology of the base network. Any alternative design can be used to update the base network.

Protection Devices Coordination
Using software to design, simulate and analyze Time Over-Current protection for Industrial, Commercial and Distribution Power systems. The program comes with an extensive database of over 5000 protective devices that are easily called to produce Time-Current curve plots and device settings reports. It also features a unique Coordination wizard to suggest protective device settings/adjustments and ratings.

Harmonic Modelling, Simulation and Analysis
To design and perform harmonic penetration analysis in electric distribution systems. The software features a full three-phase modelling capability fully integrated with power system modelling module for the analysis of resonance conditions associated with capacitor banks installed on the distribution system.
It is specifically designed for utility-type grids and distribution feeders of any configuration. This software utilizes state of the art sparse matrix/vector methods with a three-phase nodal admittance network matrix representation. The frequency scan can be performed at any joint of a feeder by simply selecting the desired section and run the analysis.
Contingency Analysis
Using software to design and study the impact of single forced or planned outages on the electrical distribution system. It finds the optimal switching plan to restore electrical power to priority customers and to recover the maximum possible load in the affected areas.
Restrictions may be set on selected switching devices so they are not considered in the switching plan. Contingencies may be set at the substation, circuit or component level, meaning that you may study the impact of losing a transformer-bank in the substation or simply simulate a damaged component on the main feeder.

Switching (Tie Point) Optimization Module
Using program to help distribution engineers determining the optimal feeder configuration in order to minimize losses, improve the voltage profile and balance the load between feeders. This service also can determine the optimal location of the tie points by suggesting new locations (addition of switching devices) or recommended switching for existing devices in order to achieve the selected objective.
This service will suggest the closing/opening of existing switching devices or to place new ones to find the configuration that will minimize losses, hence lower the operating cost, while respecting the user-defined constraints such as voltage thresholds and loading limits. It may also be used to recommend switching in order to minimize abnormal conditions such as overloaded equipment and low voltage conditions, and to minimize unbalance loading among interconnected feeders.
Substation Modelling and Analysis
Using program to model all the major components of the distribution substation and any sub-network such as the detailed modelling of an industrial facility. With the graphic editor, One Line Diagram of the substation is built. This includes the representation of bus bars, multiple transmission line feeds, power transformers, tie points and protective devices.
The distribution feeder sources are now the transmission lines feeding the substation. The impact of all components of the substation as well as all components of the feeders connected to it are now taken into consideration during the analysis.
The substation allows the user to analyze the effects of a change in the nominal operating condition of one feeder on another.

Reliability Assessment
Using program to assessing the reliability of electric distribution networks. The program computes a set of predictive reliability indices for the overall system and their corresponding protection zones such as MAIFI, SAIFI, SAIDI, CAIDI, ASAI, ENS (Energy Not Supplied), AENS and LEI. It also compute customer point indices such as the frequency of interruption, the duration, etc., for each customers. The program, also used to calibrate the

predictive model based on historical data. This functionality is very handy to adjust the failure rates and repair time for the overhead lines and cables in order to match the simulated model with historical indices.
It also allows to display all historical failures data on the diagram and color code it based on the number of outages, the causes, the type of failures, etc. It provides a high degree of flexibility for analyzing distribution system configurations.
