Electrical Network Model Synchronization for FDIR and VVC Components
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In electrical networks like power grids, fault detection, fault isolation, and load restoration (FDIR) components and voltage/var control (VVC) components often make suboptimal decisions due to a lack of current information about changes made by each other, leading to inefficiencies in decision-making processes.
Innovation Solution
An electrical network model is maintained and synchronized between the FDIR and VVC components, providing up-to-date information on device connections, measurements, and network changes, allowing both components to make informed decisions based on accurate and timely data.

Engineering Contradiction Analysis
1Reliability
If FDIR and VVC components operate independently without synchronization, then each component can execute its function autonomously, but both components make suboptimal decisions due to using stale information about network changes
Solution Approach 1:
The patent implements a feedback mechanism where the FDIR component notifies the VVC component of network changes (such as breaker switch status changes) and the VVC component notifies the FDIR component of voltage adjustments. This bidirectional feedback ensures both components have current information about network state, resolving the information asymmetry problem and enabling optimal decision-making by both components.
Solution Approach 2:
The patent introduces an intermediary communication interface that facilitates information exchange between the FDIR and VVC components. This intermediary mechanism allows structured notification of network changes and voltage adjustments, ensuring synchronized operation without requiring direct coupling between the components, thus maintaining autonomy while achieving information sharing.
2Productivity
If FDIR and VVC components share real-time information about network changes, then both components can make optimal decisions, but the system complexity increases due to required communication and synchronization mechanisms
Solution Approach 1:
The patent extracts the synchronization functionality into separate notification mechanisms within each component. The FDIR component contains a notification module for informing VVC of network changes, and the VVC component contains a notification module for informing FDIR of voltage adjustments. This extraction reduces coupling complexity while maintaining the necessary information exchange for optimal operation.

AI summary
Among other things, one or more techniques and/or systems are provided for maintaining an electrical network model describing an electrical network. A fault detection, fault isolation, and load restoration (FDIR) component, a voltage/var control (VVC) component, and/or other components may be provided with access to the electrical network model so that the components may have access to relatively up-to-date and/or accurate information describing the electrical network when executing functionality for the electrical network. For example, the FDIR component and the VVC component may be synchronized based upon the electrical network model so that the FDIR component may have notice of network changes by the VCC component, and/or the VCC component have may have notice of network changes by the FDIR component.
