In an era where modern construction increasingly relies on sophisticated power electronic equipment, a new research breakthrough promises to enhance the reliability and efficiency of electrical systems. A team led by XIAO Xiong from the Engineering Research Institute at the University of Science and Technology Beijing has developed an innovative method for real-time detection and prediction of abnormal grid voltages. This advancement is particularly crucial as the sensitivity of contemporary electronic devices to non-stationary, time-varying voltage signals can lead to severe operational disruptions.
The method employs a linear tracking differentiator to filter out conventional noise that often obscures voltage signals. By doing so, it enables precise detection of voltage anomalies, allowing for timely warnings to be sent to control circuits of power electronic devices. Xiong emphasizes the significance of this research, stating, “Our approach not only enhances the speed of fault detection but also significantly improves the efficiency of power electronics operation, which is vital for the construction sector that relies heavily on these technologies.”
One of the standout features of this method is its integration with wavelet transform modulus maxima for singularity detection. This advanced technique allows for accurate forecasting of potential harm points in power electronic devices, effectively preventing damage before it occurs. The implications for the construction industry are profound; as power systems become more reliable, construction projects can proceed with greater confidence in their electrical infrastructure.
Simulation and experimental results have shown that this wavelet analysis, when used in conjunction with the linear tracking differentiator, yields the best approximation of ideal signals. This not only enhances the quality of forecasting signals but also translates into tangible benefits in terms of reduced downtime and maintenance costs for construction projects. As Xiong notes, “By providing more useful forecasting signals, we can help construction firms avoid costly interruptions and ensure smoother project timelines.”
The research, published in the journal ‘工程科学学报’ (Journal of Engineering Science), marks a significant step forward in the field of electrical engineering and its applications in construction. As the industry continues to evolve, the ability to predict and mitigate electrical faults in real-time will undoubtedly shape future developments, leading to smarter, more resilient construction practices.
