Real-Time Electrical Consumption Measurement and Modulation System
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing systems for measuring and modulating electrical consumption do not effectively address frequency and voltage disturbances in electrical distribution networks, limiting their ability to correct anomalies both downstream and upstream of the measurement point.
Innovation Solution
A real-time measurement and modulation system that calculates frequency and voltage differences between nominal and actual values, generates alert signals, and sends selective isolation commands to electrical appliances, allowing for corrective measures regardless of their position relative to the affected electrical line portion.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a central control device measures voltage and frequency anomalies locally and modulates electrical power by connecting or disconnecting appliances downstream, then local electrical line anomalies can be addressed, but anomalies upstream of the measurement point cannot be corrected
Solution Approach 1:
The patent inverts the conventional approach by enabling corrective actions to be applied upstream of the measurement point, not just downstream. The central control device can identify anomalies originating upstream and selectively disconnect appliances upstream of the anomaly source, reversing the traditional unidirectional control flow and expanding the system's ability to address network-wide issues.
Solution Approach 2:
The patent introduces a communication network as an intermediary between the central control device and the distributed appliances. This mediator enables the central device to receive status information from and send control commands to appliances throughout the network, facilitating coordinated response to electrical anomalies regardless of their location relative to the measurement point.
2Loss of information
If periodic measurements are sent every ten minutes to an external platform, then electrical consumption can be tracked and managed, but real-time response to frequency and voltage disturbances is delayed
Solution Approach 1:
The patent implements dynamic measurement and communication intervals rather than fixed periodic updates. The system can adjust the frequency of measurements and data transmissions based on network conditions and anomaly detection, enabling rapid response to critical events while maintaining routine consumption tracking at lower intervals during normal operation.
Solution Approach 2:
The patent establishes a feedback loop where measurement results are immediately communicated back to the central control device, which can then trigger real-time control actions. This closed-loop system enables the network to respond dynamically to detected anomalies rather than waiting for scheduled update intervals, bridging the gap between continuous monitoring and periodic reporting.
Data Source
AI summary
A method is provided for measuring and modulating in real time the electrical consumption of electrical appliances. The method includes measuring in real time the current consumed by each of the electrical appliances on each electrical line portion on which each electrical appliance is situated and extracting the frequency and the voltage of the electrical signal on each electrical line portion. The difference in frequency are calculated and an alert signal is generated associated with an electrical line portion when the difference in frequency on this electrical line portion is greater than a predetermined frequency threshold value (fthreshold) and/or the difference in voltage on this electrical line portion is greater than a predetermined voltage threshold value (Vthreshold).
