Operation and Monitoring of Power Distribution and Supply Networks
A reliable supply in medium- and high-voltage grids – today and in the future – is mainly based on two parameters: Safety and Flexibility.
Safety is provided by our solutions for medium and high voltage. Our solutions for medium- and high-voltage grids include the necessary control technology, telecontrol and automation technology as well as other necessary components to create a future-proof communication infrastructure. We at VIVAVIS offer an extensive portfolio of software, hardware and services for the operation and monitoring of both medium- and high-voltage power distribution and supply grids.
Flexibility is provided by our components, which are highly scalable to the required range of functions and data model size. Our components are quickly and safely adapted to the actual conditions and circumstances. Moreover, our team of experts is able to provide specialised solutions that are adapted to your own business processes and use cases.Request now
Functions and features
Topological colouring variants enable special power grid analyses. Operators are thus able to view their power grids from different perspectives. Your required grid perspective can also be determined as part of the solution finding process.
Topological power grid states can be utilised in the ADMS processing mode and further processed using the function “topological arithmetic values”. This allows you to create added value that goes beyond the usual limit considerations.
Apart from single switching operations, this function also enables the safe and easy execution of typified switching sequences and works in the power grid, such as the exchange of busbars.
Topological markings and provisional features provide support for service and maintenance works. In the event of faults in the power grid, the power grid topology provides earth fault and short circuit localisation functions which evaluate information from the secondary protection devices in order to localise the fault location as precisely and quickly as possible.
The (n-1) Grid Failure Calculation function ensures safety in enmeshed power grids. This calculation model serves for the assessment of a power grid with regard to equipment overloads and voltage limit violation of busbars if individual components of the power grid break down.
Distribution networks with a less sophisticated measuring infrastructure can be calculated online via the load-flow calculation function. The grid is continually monitored for overload and voltage limit violations, emitting alarms and providing visualisations.
Prior to each switching operation, the load-flow calculation carries out calculations and visualisation of potential component overload and voltage limit violations which are automatically included in the topological interlock check. The load-flow calculation can also be used in the simulation mode, enabling the operators to safely prepare extensive switching operations.
In combination with a feed-in and consumption forecast, the forecast-based load-flow calculation can be used to calculate future operating conditions in advance. The system informs you about potential future bottlenecks. Thereby enabling you to initiate suitable countermeasures and check them beforehand in the simulation mode.
By setting potential fault locations in the simulation mode, users can calculate different short-circuit scenarios. The basic scope of this function also includes the calculation of double earth faults (two single-pole faults at different conductors and locations).
