Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current power systems face challenges in achieving a single source of truth for engineering and operation, managing data and assets, lack of centralized protection relay database information, manual processes for relay settings, and costly manual retrieval of disturbance records, which affect system reliability and stability.
Innovation Solution
A remote management system for asset and protection relays, including a centralized enterprise protection asset management solution that integrates data management, personnel training, systems integration, maintenance testing, and change management workflows, utilizing a processor and memory to provide remote configuration, monitoring, and data storage, along with integration with digital twin models and fault analysis systems.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If manual processes are used for relay settings upload and download, then personnel can directly access and modify relay configurations, but the process becomes tedious and time-consuming
Solution Approach 1:
The patent introduces a centralized server as an intermediary between personnel and protection relays. The server hosts a web-based interface that enables remote access and configuration of relay settings without requiring physical presence or direct manual access to the relay devices, thereby simplifying operations and reducing time consumption.
Solution Approach 2:
The patent replaces manual mechanical processes (physically accessing relays, manually copying settings) with automated electronic systems. The web server automatically retrieves, stores, and transmits relay configuration data, eliminating the need for manual intervention in settings management.
2Reliability
If centralized protection relay database information is implemented, then a single source of truth is achieved, but system complexity increases
Solution Approach 1:
The centralized server performs multiple functions: it stores relay configuration data, provides web-based access interface, manages disturbance records, and supports multiple users simultaneously. This multi-functional approach consolidates what could be multiple separate systems into a single platform, reducing overall complexity while maintaining data consistency.
Solution Approach 2:
The patent creates a digital copy of relay configuration data and disturbance records stored on the centralized server. This digital twin approach allows personnel to access and analyze relay information remotely without affecting the actual relay devices, ensuring data consistency while simplifying access procedures.
3Productivity
If remote management system is implemented, then manual effort is reduced, but integration complexity with different relay makes and models increases
Solution Approach 1:
The web server is designed to handle multiple types of protection relays from different manufacturers through a unified interface. It can retrieve and store configuration data and disturbance records from various relay models using standardized communication protocols, eliminating the need for separate management systems for each relay type.
Solution Approach 2:
The server acts as an intermediary layer between the diverse relay devices and the users. It handles the complexity of different communication protocols and data formats from various relay makes and models, presenting a uniform web-based interface to users while managing the integration complexity internally.
