A common complaint with older versions was unexpected crashes, especially during long parameter sweeps. DIgSILENT rebuilt the memory management system for the x64 release.
In a survey of 200 beta testers (including major TSOs like TenneT and National Grid), 94% rated the 2022 x64 version as "more stable" than the 2021 release.
For decades, power system simulation has been a balancing act between accuracy and available computational memory. With the release of DigSILENT PowerFactory 2022 (x64), that balance has finally tipped decisively in favor of the engineer.
While iterative updates have brought new features over the years, the 2022 release is not merely an incremental patch; it is a fundamental architectural shift. By moving entirely to a native 64-bit environment, PowerFactory 2022 redefines what is possible in grid modeling, large-scale data handling, and real-time simulation. digsilent powerfactory 2022 x64 better
Here is why the x64 version is undeniably better.
Let’s break down who benefits most:
| User Type | Why 2022 x64 is Better | |-----------|------------------------| | Transmission Planner | Run EMT for entire interconnection with 500+ IBRs. | | Distribution Engineer | Model entire city with 10,000+ nodes, including unbalanced loads. | | Researcher (PhD/Uni) | Parallelize monte carlo simulations for probabilistic studies. | | Consultant | Faster turnaround on grid code compliance studies. | | Industrial Plant Engineer | Harmonic insertion method for arc furnace flicker analysis. | | Offshore Wind Developer | MMC-HVDC models + detailed cable frequency-dependent models. | A common complaint with older versions was unexpected
If you work primarily on small radial distribution feeders without dynamics, the upgrade may be less critical. But for anyone dealing with transients, harmonics, or large systems—the x64 version is non-negotiable.
While the 2022 x64 version is backward compatible with most older projects, some legacy custom DLLs (User Models) compiled for 32-bit will not work. You will need to recompile them for x64. Additionally, check your Python libraries to ensure they are also 64-bit.
| Task | PowerFactory 2021 (x86) | PowerFactory 2022 x64 | Improvement | |------|------------------------|-----------------------|--------------| | Load flow on 10,000-bus system | 12 sec | 4 sec | 3x faster | | RMS stability (60 sec simulation) | 8 min | 2.5 min | 3.2x faster | | EMT simulation (2 sec, 20 µs step) | Memory crash | 6 min | Infinite (feasible now) | In a survey of 200 beta testers (including
Absolutely. If you are currently running PowerFactory 2021 or earlier on a modern Windows 10/11 workstation with 16GB+ of RAM, you are leaving significant performance on the table.
For over three decades, DIgSILENT PowerFactory has been the gold standard for power system analysis, used by utilities, consultants, and research institutions worldwide. However, every seasoned engineer knows that software evolution isn't always linear. Some versions bring minor tweaks; others—like the 2022 x64 release—bring a paradigm shift.
If you have been asking, “Is DIgSILENT PowerFactory 2022 x64 better than its predecessors?” the short answer is a resounding yes. But the long answer requires a deep dive into architecture, performance, feature sets, and real-world usability.
In this article, we will explore exactly what makes the 2022 x64 version superior, from memory handling to cutting-edge grid modeling.
