The Tele2 Speedtest Service helps you test your Internet connection speed through various methods and is available not only to customers of Tele2 but anyone with an Internet connection. Test your connection using speedtest.net's tool, downloading a file via your web browser (HTTP) or downloading and uploading via FTP.

Speedtest is run on a number of fast servers in locations throughout Europe connected to Tele2's international IP core network with 10GE. The address http://speedtest.tele2.net is anycasted, meaning that you should automatically be served by the server closest (network wise) to your location. Read more about the technical details of this service.

You are currently being served by xxx-SPEEDTEST-1 located in City, Country.

We provide a variety of testfiles with different sizes, for your convenience.
1MB 10MB 100MB 1GB 10GB 50GB 100GB 1000GB md5sum sha1sum
These are sparsefiles and so although they appear to be on disk, they are not limited by disk speed but rather by CPU. The Speedtest servers are able to sustain close to 10 Gbps (~1GByte/s) of throughput. See the technical details to learn more about sparse files and the setup of the Tele2 Speedtest service.

To download on a Unix like system, try wget -O /dev/null http://speedtest.tele2.net/10GB.zip

After some requests we have also added the possibility to upload data using HTTP:

$ curl -T 20MB.zip http://speedtest.tele2.net/upload.php -O /dev/null

Siemens Psse New! — Certified & Popular

“Elena, we applied your PSS/E solution. Phase-shifter is now reacting to the western oscillation. The thermal alarm just cleared. How did you know?”

Evaluating the impact of unplanned outages on grid reliability.

Universities, national laboratories, and regulatory agencies utilize PSS®E to model entire continental grids. These models help formulate energy policies, evaluate the impact of market designs, and study macro-trends like the cross-border integration of super-grids. Why Choose Siemens PSS®E Over Competitors?

Solves nonlinear algebraic network equations using robust iterative methods like Newton-Raphson or Fixed-Slope Decoupled algorithms. siemens psse

As the world transitions to a more decentralized and decarbonized grid, software tools must adapt. High penetration levels of wind and solar—which act differently than traditional, massive spinning coal or nuclear generators—present unique challenges to system inertia and frequency stability. Siemens continues to actively develop PSS®E, offering continuous updates to its dynamic libraries, improving co-simulation capabilities for Transmission and Distribution (T&D) networks, and enhancing tools for managing high-voltage direct current (HVDC) integrations.

One of the distinguishing features of PSS®E is its architecture. Unlike "black box" software, PSS®E offers a high degree of transparency and customization.

PSS®E includes standard libraries for modeling wind turbines (e.g., Type 3 and 4) and solar PV plants. Complex Load Models: “Elena, we applied your PSS/E solution

PSS®E is engineered to compute massive network models without sacrificing speed. Its advanced sparse-matrix algorithms can solve load flows for networks exceeding 100,000 buses in mere seconds. High Automation via Python Integration

Calculating voltages, currents, and power flows under various load conditions.

In an era defined by rapid grid decarbonization, the explosive growth of renewable energy sources, and the critical need for resilient electrical infrastructure, modern grid planning demands absolute analytical precision. For over four decades, has served as the foundational industry standard for electrical transmission planning and analysis. Used globally by transmission system operators (TSOs), system planners, utilities, and researchers, this comprehensive software suite mitigates risks and optimizes massive capital investments in power infrastructure. 🛠️ Core Capabilities of Siemens PSS®E

Siemens has adapted PSS/E to this new reality, integrating sophisticated models for renewable energy and high-voltage direct current (HVDC) links. The software now grapples with low-inertia systems where frequency deviations can happen faster than traditional governors can react. This evolution highlights the software's architectural flexibility; it has transitioned from modeling a mechanical grid to an electronic one. Features that model "synthetic inertia" from wind farms or the complex control logic of solar inverters are now critical components of the PSS/E suite, ensuring the software remains relevant as the grid decarbonizes.

Evaluates bus voltages, line flows, and transformer loadings under various operating conditions and contingencies. Dynamic Simulation:

How will the addition of a massive offshore wind farm affect power quality?

PSS®E can handle networks exceeding hundreds of thousands of buses without sacrificing numerical stability or calculation speed.
