Medium-Voltage Waveform Recording for Cross-Phase Event Coordination
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In medium voltage distribution networks, events on a single phase may not trigger monitoring devices on other phases, resulting in limited data availability for understanding and mitigating the event.
Innovation Solution
A monitoring device with sensors, a communication module, and a controller is used to sense parameters, determine events, and coordinate with other monitoring devices via a communication module, transmitting event data to a data aggregator.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If monitoring devices operate independently on each phase, then device complexity is reduced, but data availability for comprehensive event analysis deteriorates
Solution Approach 1:
The patent merges monitoring data from multiple phases by having monitoring devices transmit event information across phases through a communication network. When an event is detected on one phase, coordination signals trigger other phase monitoring devices to share their data, effectively combining distributed monitoring capabilities into a unified event analysis system without requiring physically integrated devices.
Solution Approach 2:
The communication network acts as an intermediary that enables information exchange between independently operating monitoring devices on different phases. This mediator allows event data, coordination signals, and event information to be transmitted across the distribution network, connecting previously isolated monitoring systems while maintaining their operational independence.
2Loss of information
If monitoring devices transmit data across phases, then data availability for event analysis is improved, but device complexity increases
Solution Approach 1:
The patent implements preliminary action by pre-configuring monitoring devices with event detection capabilities and coordination signal transmission functions. Before events occur, devices are prepared to immediately detect events on any phase and transmit coordination signals to trigger data sharing, eliminating the need for complex real-time decision-making during actual events.
Solution Approach 2:
Monitoring devices are designed with multi-functionality, serving both local phase monitoring and cross-phase event coordination roles. Each device can detect events on its local phase, transmit coordination signals to other phases, and receive event information from other phases, making a single device type sufficient for all monitoring needs without requiring specialized equipment for each function.
3Measurement precision
If event data is collected from multiple phases, then measurement precision for event characterization is improved, but loss of time for data collection increases
Solution Approach 1:
The patent uses periodic action through event-driven triggering mechanisms. Instead of continuously collecting and transmitting data from all phases, the system periodically activates data collection only when events are detected. Coordination signals trigger immediate data retrieval from affected phases, creating a periodic rather than continuous operation mode that reduces overall data collection time while maintaining precision when events occur.

AI summary
Systems and methods for coordinating monitoring devices associated with a medium voltage distribution system. The systems include a data aggregation device, a first monitoring device associated with a first phase of the medium voltage distribution system, and a second monitoring device associated with a second phase of the medium voltage distribution system. The first monitoring device is configured to sense one or more parameters of the first phase, store the one or more stored parameters, and determine whether an event has occurred based on the sensed parameters. The first monitoring device is further configured to transmit a coordination signal to a second monitoring device in response to determining the event has occurred and a first event message to a data aggregator device in response to determining the event has occurred, wherein the event message includes one or more sensed parameters associated with the determined event.
