Product Description
Contingency Analysis and Resupply (CA)
Requirements and Use Cases
The aim of the contingency analysis is to evaluate the load flow in the event of malfunction of equipment and network feeders. The contingency analysis provides the network operator with information about the operational safety and reliability of the network. The aim is not only to evaluate the malfunction itself, but also to analyze possible strategies for the resupply of all consumers. The network operator needs information regarding:
- Supply interruptions and ways of removing them rapidly
- Detection of impermissible network conditions (voltage deviations, overloads) in the event of equipment malfunction
- Checking the n-1 or n-1-1 (n-2) criterion in the network
- Checking the network during planned maintenance work/shutdown of individual or several devices
- Checking of predefined malfunction scenarios with remedial measures
- Evaluation of the priority of network development measures regarding the (n-1) security and the resupply possibilities of the network
Solution
The contingency analysis and resupply (CA) module in PSS®SINCAL automatically simulate the malfunction of equipment in the network and evaluates the network status during these malfunctions.
- Automatic generation of malfunctions of lines, transformers, generating plants, network nodes and user-defined malfunction groups according to user specifications for the n-1 case
- Automatic generation of malfunctions depending on predefined utilization limits of equipment and based on probabilistic parameters
- Simulation of the n-1-1 (n-2) case or of caused malfunctions due to the changed utilization of equipment in the n-1 case
- Comprehensive and interactive visualization of malfunctioned and non-supplied network elements, limit violations and maximum loading
- Display of all calculated malfunctions in the result browser for analysis, recalculation and filtering of malfunctions
Remedial measures can also be analyzed in the contingency analysis if required. If network elements have malfunctions, an attempt is made to resupply all supplied consumers (loads, asynchronous machines, etc.) in a valid operating state.
- Automated resupply through switching measures, load shedding and load reduction
- Support of topological and feeder-based resupply strategies with user-defined settings
- User-defined remedial measures as scenarios, by which for example complete RAS (Remedial Action Schemas) can be simulated
PSS®SINCAL Massive and Parallelized Analysis Modules
