Methodology
1
Data Collection and Validation
After signing an NDA, we provide you with a detailed list of the data to be collected and guide you in its inventory from the various relevant departments (operations, mapping, customer service, IT, etc.). As the data is transmitted, we verify its conformity with the expressed need.
2
Completeness and Consistency Check
We verify the completeness and consistency of the data. Usually, approximately 99% of the errors detected can be processed automatically; the others are corrected manually.
3
Association of Electrotechnical Models
Thanks to our component catalog, each asset is associated with its electrotechnical model and the corresponding technical characteristics. If your equipment does not appear in the catalog, it is added.
4
Reconstruction of Network Connectivity
The detail of the electrical connectivity between the different assets is reconstructed. For each object, the upstream and downstream assets are defined. The network’s open points are defined.
5
Database Export
The electrical model of the network is exported into a standardized database and can be imported into electrotechnical software.
Deliverables
Simplify your process and improve your data quality
1
Up-to-date electrical model
Start your study without delay
Increase efficiency by avoiding manual network tracing: your up-to-date network model is directly available in your electrotechnical study software. You can focus on what matters most: analysis and decision-making.
2
Log of corrections made
Increasingly reliable network data
Improve the quality of your network data thanks to the log of applied corrections. Missing attributes, inconsistencies between data sources, outliers: thanks to the continuous correction of erroneous entries, you guarantee the quality of decision-making.
Roseau ETL, software dedicated to network data processing
Our Tools
To get the most out of your data, we designed Roseau ETL, an advanced tool dedicated to processing network data.
Flexibility and robustness
Our software can process any input format, database schema, or projection method. It is highly configurable, so it can handle almost any type of network data!
Specificity
Unlike generic ETL (Extract-Transform-Load) tools, Roseau ETL can support all types of network-specific issues such as connectivity problems, contradictory voltage levels, or inconsistent sizing of lines or transformers.
Automation
Roseau ETL automatically corrects over 95% of detected inconsistencies, thus limiting manual intervention to truly necessary decisions.

FAQ
Grid Modeling: we answer your questions
Why is it essential to rely on electrical simulation to size distribution networks?
To control costs, accurately assess the available capacity for new loads and new generation facilities, and ensure the quality of service for customers as well as the physical safety of network assets, it is paramount for electrical network planners and engineers to rely on electrical simulation to optimize investments.
Otherwise, the risk is to over-dimension the network and thus incur unnecessary expenses, or conversely to under-dimension a structure whose lifespan will consequently be reduced. Its premature replacement will thus constitute a non-optimal expense.
Are electrotechnical software programs ready to use?
Specialized electrotechnical software is often provided without preloaded data. This means that the user must integrate their own network data, or even redraw the network manually.
This “network model” describes the physical characteristics of each element of the network under study and how they are connected to each other.
Why can't mapping data be used directly in network simulation software?
Mapping data is not directly usable in network simulation software. Data structures differ considerably between these two types of software, and it is often necessary to detect and correct numerous data quality problems during conversion.
In addition, maps do not contain all the necessary information, such as operating data, customer information, and the electrotechnical characteristics of each asset.
What data is needed to model an electrical distribution network?
Some data is essential to create an accurate electrical model of a distribution network. For example, it is crucial to have a map of the network structure, even if it is not extremely precise.
On the other hand, some data can be estimated in the absence of reliable information. For example, it can be assumed that off-load taps are left in the middle position. These assumptions can be adjusted on a case-by-case basis during the simulation.
We specialize in formulating these assumptions and can assist you in choosing them. For example, we have already modeled the entire French distribution network, even though only the locations of the assets were available!
