Logical Device Profiles for Faster SCADA Alarm Source Identification
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In complex power systems, identifying specific monitoring and control devices within Supervisory Control and Data Acquisition (SCADA) systems is challenging due to the numerous similar devices, making it difficult to rapidly locate the source of alarms or perform data and control functions efficiently.
Innovation Solution
The implementation of logical device profiles that group physical devices into composite objects, allowing the SCADA system to manage and communicate with them as single logical devices, using a profile editor to create and manage these profiles, which include tags for inputs and outputs, enabling efficient organization and identification of devices.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If separate physical devices with separate inputs and outputs are used in a SCADA system, then the system can monitor and control numerous devices, but it becomes difficult to identify specific devices and requires substantial resources and time to manage them
Solution Approach 1:
The patent merges multiple separate physical devices into a single composite device profile. The profile aggregates inputs and outputs from multiple devices (e.g., multiple IEDs in a switchgear panel) into one unified logical representation, allowing the SCADA system to manage them as a single entity while retaining the ability to identify individual device sources through profile attributes.
2Area of stationary object
If numerous control devices and monitoring devices are deployed, then the system coverage is improved, but the time and resources required to locate specific devices increase substantially
Solution Approach 1:
The patent introduces a new organizational dimension by creating hierarchical profiles. Instead of flat device listings, the system organizes devices into composite profiles with nested structures (e.g., switchgear panels containing multiple IEDs). This dimensional reorganization enables rapid device location through profile navigation and attribute-based searching, reducing the time to locate specific devices despite increased system coverage.
3Reliability
If separate physical devices are used with separate inputs and outputs, then each device can be independently monitored, but the complexity of managing numerous similar or identical control devices increases
Solution Approach 1:
The patent creates universal composite device profiles that can represent multiple different physical devices through a common structure. The profile template includes standardized attributes and input/output definitions that can accommodate various device types (circuit breakers, relays, IEDs, etc.), reducing system management complexity while maintaining independent monitoring capabilities through the profile's structured organization.

AI summary
A system and methods for creating a logical profile for physical devices in a system to interface with a monitoring system is disclosed. A profile identity is selected. A plurality of physical devices from the system is selected. The physical devices such as a meter or a circuit breaker include an output or an input. An input or output is classified for at least one of the plurality of selected physical devices as a tag. The plurality of selected physical devices are represented to the monitoring system by the profile identity and the at least one tag of the selected physical devices.
