Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing intelligent electronic devices in substation and distribution automation systems lack flexibility in hardware and software configurations, making it difficult to adapt to varying environmental requirements such as different I/O connections and communication protocols, while adhering to standards like IEC 61850.
Innovation Solution
A modular intelligent electronic device with mechanically separable and replaceable hardware modules interconnected via an inter-module bus, including a communication module for network communication and I/O modules for local equipment, allowing user-selectable configurations that follow the IEC 61850 standard, enabling flexible hardware and software combinations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If traditional fixed-configuration intelligent electronic devices are used, then device stability and standard compliance are maintained, but flexibility and adaptability to varying environmental requirements deteriorate
Solution Approach 1:
The IED is divided into multiple functional modules (power supply module, communication module, processing module, I/O module) that can be independently selected and configured. Each module performs a specific function and can be combined with other modules to create different device configurations suitable for various application environments.
Solution Approach 2:
The modular architecture enables a single IED platform to serve multiple functions and applications. By selecting different combinations of modules, the same base device can be adapted for protection, monitoring, control, and communication tasks across different electrical systems and environments.
2Adaptability or versatility
If modular hardware is implemented to improve flexibility, then adaptability to different environments is improved, but device complexity and integration difficulty worsen
Solution Approach 1:
The device is segmented into standardized modules with defined interfaces and communication protocols. This segmentation allows each module to be manufactured, tested, and validated independently, then integrated into the complete IED system through standardized connection mechanisms.
Solution Approach 2:
Standardized communication buses and interface protocols act as intermediaries between modules, enabling seamless data exchange and coordination. The inter-module communication infrastructure mediates interactions between power supply, processing, I/O, and communication modules, simplifying integration.
