PowerFactory 15.2 50: What's New and Why You Should Upgrade

DIgSILENT PowerFactory 15.2 50: A Comprehensive Power System Analysis Software


Power system analysis is a vital task for ensuring the reliable, efficient, secure, and economical operation of electrical networks. It involves studying various aspects of power system behaviour, such as load flow, short circuit, stability, protection, optimization, power quality, reliability, etc. To perform such studies, power system engineers and operators need a powerful software tool that can handle complex network models, perform accurate calculations, provide user-friendly interfaces, offer flexible options, support different standards and formats, and deliver comprehensive results and reports.

One of the most widely used and trusted software tools for power system analysis is DIgSILENT PowerFactory. PowerFactory is a fully integrated software package that covers all aspects of power system modelling, analysis, simulation, and optimization. It can handle any type of network, from transmission to distribution, from AC to DC, from conventional to renewable, from steady-state to dynamic, from deterministic to probabilistic. It can also support various applications, such as planning, operation, control, protection, market analysis, education, research, etc. PowerFactory is used by more than 2000 customers in over 140 countries around the world.

PowerFactory is constantly being updated and improved to meet the changing needs and challenges of the power system industry. The latest version of PowerFactory is 15.2 50, which was released in June 2021. This version introduces many new features and enhancements that make PowerFactory even more powerful, flexible, user-friendly, and efficient. In this article, we will review some of the most important and interesting features and enhancements of PowerFactory 15.2 50 and explain how they can help power system engineers and operators perform better power system analysis.

General improvement of calculation speed

One of the main advantages of PowerFactory 15.2 50 is the significant improvement of calculation speed for various types of power system analysis. This improvement is achieved by using state-of-the-art solvers and improved data structures that enhance the performance and accuracy of power system calculations. For example, PowerFactory 15.2 50 uses a new sparse matrix solver for load flow and short circuit calculations that can handle large and complex network models with high efficiency and precision. The new solver can also exploit parallel processing capabilities of modern CPUs to speed up the calculations even further.

Another example of speed improvement is the use of new algorithms and precompiled controller models for dynamic simulation and stability studies. PowerFactory 15.2 50 uses a new numerical integration method for dynamic simulation that can handle stiff systems with high accuracy and stability. PowerFactory 15.2 50 also uses precompiled controller models for generating units, converters, FACTS devices, etc., that can reduce the simulation time by up to 80% compared to interpreted models. These features allow PowerFactory users to perform faster and more reliable dynamic simulation and stability studies for various scenarios and contingencies.

New and flexible Heatmap background colouring scheme

A Heatmap is a graphical representation of network data and results using different colours to indicate different values or ranges of values. A Heatmap can help visualize network conditions and identify potential issues or opportunities in a quick and intuitive way. PowerFactory has been supporting Heatmap functionality for many years, but PowerFactory 15.2 50 introduces a new and flexible Heatmap background colouring scheme that allows users to customize the Heatmap settings and apply different colour schemes for different scenarios and parameters.

With the new Heatmap background colouring scheme, users can define their own colour scales and thresholds for any network parameter or result, such as voltage magnitude, voltage angle, active power flow, reactive power flow, loading percentage, short circuit current, etc. Users can also choose from predefined colour scales or use custom colours for each value or range of values. Users can also apply different Heatmap settings for different study cases or scenarios to compare the network performance under different conditions. The new Heatmap background colouring scheme provides more flexibility and convenience for users to create their own Heatmaps according to their preferences and needs. dcd2dc6462
