Bulk Low-Inertia Power Systems Adaptive Fault Type Classification Method Based on Machine Learning and Phasor Measurement Units Data

Sep 17, 2026

This research develops and tests an adaptive method for classifying power-system disturbances by combining machine learning with phasor measurement unit (PMU) data. Ensemble models—including Random Forest, AdaBoost, XGBoost, and LightGBM—are trained and evaluated for both synthetic disturbances from transient simulations of the IEEE 24 bus test system and real transient events. XGBoost delivers the best results: 96.8% accuracy on synthetic data and 85.2% on physical data. Sampling frequency and calculation-window length are also analyzed, showing limited accuracy gains beyond 5 kHz and 5 ms.

To enhance the speed and accuracy of disturbance classification, we employ a range of ensemble machine learning techniques, including Random forest, AdaBoost, Extreme gradient boosting (XGBoost), and LightGBM. The classification method was evaluated using both synthetic data, generated from transient simulations of the IEEE24 test system, and real-world data from actual transient events in power systems. Among the algorithms tested, XGBoost achieved the highest classification accuracy, with 96.8% for synthetic data and 85.2% for physical data. Additionally, this study investigates the impact of data sampling frequency and calculation window size on classification performance. Through numerical experiments, we found that increasing the signal sampling rate beyond 5 kHz and extending the calculation window beyond 5 ms did not significantly improve classification accuracy.

Introduction The key trends in the development of modern electric power systems (EPS) include the widespread adoption of digital devices for recording, collecting, and analyzing electrical parameters [1,2], the accelerated integration of renewable energy sources (RES) [3–7], and the expansion of permissible operating conditions enabled by digital monitoring systems and adaptive control [8–11] . A notable characteristic of modern EPS is the reduction in system inertia, resulting from the growing share of RES alongside the retirement of fossil fuel power plants. This reduction in inertia leads to faster transient processes and diminishes the effectiveness of emergency control systems. The greatest impact of change
