PowerFactory Applications
POW ER T RANSM ISSIO N
PowerFactory offers a complete suite of functions for studying large interconnected power systems integrating new technologies for power generation and transmission such as wind generation, virtual power plants, HVDC-VSC or FACTS. The fast and robust load flow algorithm can be applied to any AC or DC network topology. It uses highly accurate models including various types of MW and Mvar-controllers. PowerFactory’s functions can be applied to improve the security, stability and economics of complex power transmission systems.

POW ER DIST RIBUTION
Different phasing technologies, such as single-wire earth return, two-phase, bi-phase or classical three-phase systems, have created a need for multi-phase distribution system modelling. PowerFactory provides the most comprehensive modelling features for studying all kinds of phasing technologies, meshed or radial topologies and railway supply systems connected to public distribution systems. In order to reduce network unbalance, improve quality of supply and optimize distribution networks, PowerFactory offers a large variety of functions, such as multi-phase load flow analysis, short-circuit analysis (IEC 60909, ANSI C37 and multiple fault analysis), harmonic analysis, time-domain simulation and reliability assessment. Other standard features include the modelling of distributed generation and virtual power plants, voltage drop analysis, branch loading calculation, daily load curves and the consideration of LV load diversity. This is complemented by an easy-to-use protection coordination functionality. OTHER IMPORTANT ASPECTS ARE: Tie open point optimization Optimal capacitor placement Voltage profile optimization for bi-directional power flows Geographic diagrams (GPS based) with background maps GIS and SCADA integration

I N D U ST RIAL SYSTEMS
Industrial power systems supplying refineries, paper-mills, car factories or other plants with high power quality requirements benefit from high precision PowerFactory load flow algorithms, short-circuit calculation features, 4-wire modelling, harmonic analysis and filter design options. OTHER RELEVANT FUNCTIONS INCLUDE: Steady-state/ transient motor starting and plant re-acceleration Protection coordination and settings verification Stability analysis and electromagnetic transients

modelling of generation-, transmission-, distribution- and industrial grids and the analysis of the interactions of these grids. PowerFactory is the ideal tool for studying the grid integration of renewable energies.

D I S T RIBUT ED GENER ATIO N
Generation at distribution levels defines entirely new challenges for distribution planning engineers due to reverse power flows, voltage drops and extreme variations in equipment loading. Various generation technologies are possible, such as synchronous and asynchronous cogeneration units, PV-cells, wind turbines, fuel cells and micro-turbines. Typical studies include steady-state and dynamic analyses, taking into consideration time-varying correlated or un-correlated energy sources. PowerFactory is the ideal tool for analyzing the impact of distributed generation on the network. It combines classical distribution system analysis functions such as voltage drop calculation, unbalanced network, load and generation modelling, selectivity analysis, etc. with the power of a highly modern analysis tool featuring dynamic simulation functions and reliability analysis. Full support is available for developing and analysing the impact of virtual power plants and new control techniques on distribution networks.
