Load Device Timing for Automated Grid Mapping
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing systems for distinguishing groups of load devices are complex and require manual assignment of addresses, with limitations in automated commissioning and grid mapping, particularly in large-scale infrastructure like streetlamp networks where relationships between load devices and grid phases are often lost.
Innovation Solution
A system comprising load devices with detection, timing, and transmission capabilities that autonomously report switching events to a management device without pre-assigned addresses, using timers and transmitters to define switching times and IDs, allowing for differentiation between groups based on unique switching moments.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If manual assignment of addresses is used to distinguish groups of load devices, then identification accuracy is improved, but device complexity and commissioning time increase
Solution Approach 1:
Load devices automatically generate and transmit their own identification information and switching timing data without requiring manual address assignment. The system performs self-identification by detecting load switching events and reporting timing information autonomously to the management device, eliminating the need for complex manual commissioning while maintaining accurate identification.
Solution Approach 2:
The system pre-configures load devices with detection capabilities that continuously monitor load switching events. By having the detection device and timer ready in advance, the system can immediately begin automatic identification and grid mapping when deployed, without requiring step-by-step manual configuration during commissioning.
2Measurement precision
If manual intervention is used for grid mapping, then mapping accuracy is improved, but productivity and commissioning speed decrease
Solution Approach 1:
The detection device continuously monitors load switching events and provides real-time feedback to the management device through transmitted timing information. This automatic feedback loop enables the system to dynamically build and update the grid map based on actual switching patterns, ensuring accurate grid mapping while operating at high speed without manual intervention.
Solution Approach 2:
The system replaces manual mechanical commissioning processes with electronic detection and automatic data transmission. The detector electronically identifies switching events and the transmitter automatically sends timing data to the management device, substituting manual address assignment and grid mapping procedures with automated electronic processes that are both faster and equally accurate.
3Reliability
If pre-assigned addresses are used in load devices, then identification reliability is improved, but adaptability to different grid configurations decreases
Solution Approach 1:
Instead of using fixed pre-assigned addresses, the system dynamically determines identification parameters based on actual load switching timing events. The timer measures the timing characteristics of switching events, and these measured parameters are used to automatically identify load devices and their groupings. This approach maintains reliable identification while adapting automatically to different grid configurations without requiring reconfiguration.
Solution Approach 2:
The system transitions from static pre-assigned addresses to dynamic identification based on real-time switching event detection. The detection device continuously monitors and captures timing information from load switching events, allowing the system to adaptively identify devices and map grid relationships as they actually operate, providing both reliability and flexibility for various grid configurations.

AI summary
For automated commissioning for automatic grid mapping, load devices comprising a load and detection devices have the detection devices (1) communicate with management devices (2) and comprise detectors (11) for detecting switchings of loads (3), timers (12) for determining and storing timings of the switchings of the loads (3) and transmitters (12) for transmitting information to the management devices (2). This information defines the timings of the switchings of the loads (3) as well as identifications of the detection devices (1), of the loads (3), and/or of load devices (201-220) comprising the detection devices (1) and the loads (3). The timings of the switchings of the loads (3) may define moments in time. By switching different groups of loads (3) at different moments in time, the different groups can be distinguished from each other. The management devices (2) comprise receivers (21) configured to receive the information from the detection devices (1) and may further comprise controllers (22) for controlling the switchings of the loads (3) to take place at different moments in time.
