Summary
This paper addresses power safety for high-voltage sensitive industrial users in parks with distributed photovoltaics and charging piles, where harmonics and voltage fluctuations pose risks of equipment failures, fires, and outages. A closed-loop framework is developed for hazard modeling, analysis, and preemptive identification. The methodology includes: a multidimensional coupling model linking electrical parameters, equipment status, and environmental factors; a T-S dynamic fault tree with Continuous-Time Markov Chains to characterize the temporal evolution of hazards; and a quantitative evaluation using Sobol's global sensitivity analysis to rank key risk factors. A case study in a precision manufacturing park validates the approach, and a digital-analog dual-driven detection and localization system achieved over 90% accuracy in hazard identification and source tracking. This research offers a model-driven framework enabling proactive risk warning and precise hazard localization in sensitive industrial environments.
