1Length of stationary object
If impedance injection modules are distributed over long distances in power transmission systems, then power transmission coverage and system capability are improved, but communication reliability and failure detection capability deteriorate
Solution Approach 1:
A dual-ring fiber optic communication network is introduced as an intermediary to connect distributed impedance injection modules to power line coordinators. This dedicated communication infrastructure ensures reliable data transmission over long distances, resolving the contradiction between extended transmission coverage and communication reliability.
Solution Approach 2:
The system performs preliminary failure detection by continuously monitoring communication signals and module status before actual failures impact power transmission. This proactive approach allows the system to identify and respond to potential issues in distributed modules before they cause system-wide problems.
2Adaptability or versatility
If multiple impedance injection modules are distributed across long transmission lines, then power flow control capability is improved, but system complexity and coordination difficulty increase
Solution Approach 1:
The system divides the power transmission network into segments, with power line coordinators positioned at strategic locations to manage groups of impedance injection modules. This segmentation allows independent control and monitoring of each segment, reducing overall system coordination complexity while maintaining versatile power flow control across the entire network.
Solution Approach 2:
The dual-ring fiber optic network enables real-time feedback communication between impedance injection modules and power line coordinators. This feedback mechanism allows the central coordination system to monitor module status and adjust control parameters dynamically, simplifying the management of distributed modules while maintaining high adaptability.
3Measurement precision
If communication networks connect distributed impedance injection modules, then system monitoring and control are improved, but vulnerability to communication failures and network complexity increase
Solution Approach 1:
The system implements a dual-ring fiber optic communication network with redundant pathways. This redundant architecture provides beforehand cushioning against communication failures, ensuring that if one communication path fails, alternative paths maintain system monitoring and control capabilities without increasing operational complexity.
