IED Network Protocol Integration for Power Monitoring
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
High technology industries face challenges in monitoring key power system parameters within their complex networks, as existing network management systems lack the capability to measure and communicate power system data effectively, despite using energy meters and Intelligent Electronic Devices (IEDs).
Innovation Solution
Integration of Intelligent Electronic Devices (IEDs) into network management systems, configured to communicate using the network management protocol, allowing them to measure and monitor power system parameters and map these parameters to corresponding network protocol variables, enabling communication with network management stations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If network management systems use independent energy management systems with separate communication protocols, then energy monitoring capability is provided, but system complexity increases and integration with network management is lost
Solution Approach 1:
The patent merges the energy management system with the network management system by enabling IEDs to communicate power system parameter data through the existing network management protocol infrastructure. This integration eliminates the need for separate independent energy management systems while maintaining comprehensive monitoring capabilities.
Solution Approach 2:
The IEDs are configured to perform multiple functions: they continue to monitor power system parameters as before, while simultaneously communicating this data through network management protocols used by the network management system. This multi-functionality allows a single system to handle both network management and energy monitoring tasks.
2Ease of operation
If network devices provide performance data via network management protocol, then network management capability is improved, but power system parameter measurement capability remains absent
Solution Approach 1:
The IEDs act as intermediaries between the power system and the network management system. They measure power system parameters locally and translate this data into network management protocol messages, serving as a bridge that enables the network management system to access power system information without requiring direct measurement capability.
3Loss of information
If separate energy management systems are used to monitor power parameters, then power monitoring is achieved, but communication independence from network management system is required
Solution Approach 1:
The invention changes the communication parameter from using separate proprietary energy management protocols to using standard network management protocols. This parameter change in the communication interface allows the energy monitoring data to be transmitted through the existing network management infrastructure, improving adaptability and eliminating the need for separate communication systems.
