Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Power quality issues, such as voltage sags, swells, and transients, significantly impact electrical systems, leading to equipment stress, reduced lifespan, and substantial economic losses due to frequent restarts and re-energizations, which existing technologies fail to adequately address.
Innovation Solution
The implementation of intelligent electronic devices (IEDs) that process energy-related signals to identify and quantify the effects of electrical perturbations, allowing for the analysis of voltage and current signals to determine the end time of perturbations and their impact on equipment, and enabling actions to reduce these effects, such as communicating restarts and controlling system components.

Engineering Contradiction Analysis
1Reliability
If existing technologies are used to monitor electrical systems, then basic power quality detection is achieved, but equipment stress and lifespan reduction due to electrical perturbations are not adequately addressed
Solution Approach 1:
The system performs preliminary identification of electrical perturbations (sags, swells, transients) before they cause significant equipment damage. By detecting these events in real-time and analyzing their characteristics, the system can trigger protective actions or warnings that prevent equipment stress and extend lifespan
Solution Approach 2:
The system continuously monitors electrical parameters, identifies perturbations, analyzes their effects on equipment, and provides feedback for corrective actions. This closed-loop feedback mechanism enables ongoing protection against equipment stress by adjusting system operations based on detected electrical conditions
2Productivity
If equipment restarts are allowed after electrical perturbations, then equipment operational continuity is maintained, but equipment stress increases and lifespan is reduced
Solution Approach 1:
The system applies preliminary anti-action by identifying electrical perturbations and their potential to cause equipment restarts before the restarts occur. By analyzing the perturbation characteristics and predicting equipment responses, the system can take preventive measures to avoid restarts or mitigate their harmful effects, thereby reducing equipment stress while maintaining operational continuity
3Measurement precision
If comprehensive analysis of electrical measurement data is performed to identify perturbation effects, then accurate quantification of equipment impact is achieved, but system complexity increases
Solution Approach 1:
The system segments the complex task of perturbation analysis into distinct functional modules: electrical measurement data acquisition, perturbation identification, effect analysis, and quantification. Each module handles a specific aspect of the analysis, making the overall system more manageable and maintainable while achieving comprehensive measurement precision

AI summary
A method for analyzing effects of electrical perturbations on equipment in an electrical system includes processing energy-related signals from at least one intelligent electronic device in the electrical system to identify an electrical perturbation in the electrical system. An end time of the electrical perturbation may be determined, and electrical measurement data from prior to, during and/or after the end time of the electrical perturbation may be analyzed to identify and quantify the effects of the electrical perturbation on equipment in the electrical system. The effects may include, for example, equipment restarts/re-energizations due to the electrical perturbation. One or more actions may be taken or performed to reduce the effects of the electrical perturbation and extend the life of the equipment. The actions may include, for example, at least one of communicating the equipment restarts/re-energizations and controlling at least one component in the electrical system.
