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

VSEngineering 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

Engineering Contradiction:
Improvenumber of devicesVSAvoiddevice identification
Core Design Contradiction:
Quantity of substanceVSEase of operation

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.

Inventive Principle:
Principle #5Merging (Combining)

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

Engineering Contradiction:
Improvesystem coverageVSAvoiddevice location time
Core Design Contradiction:
Area of stationary objectVSLoss of time

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.

Inventive Principle:
Principle #17Another dimension (Dimensionality change)

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

Engineering Contradiction:
Improvedevice monitoringVSAvoidsystem management complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

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.

Inventive Principle:
Principle #6Universality (Multi-functionality)
