Power Converter Fault Diagnosis Dataset 核心 · 已核验

doi:10.5281/zenodo.20484337

This dataset contains electrical measurements acquired from a real-time Hardware-in-the-Loop (HIL) simulation environment developed for fault diagnosis research in power electronic converters.

The simulated system corresponds to a 2 MW two-level voltage source inverter (2L-VSI) connected to a three-phase 400/690 V, 50 Hz electrical grid and a 1500 V DC bus. The model was executed on a Typhoon HIL606 real-time simulator, enabling the controlled injection of multiple fault conditions while preserving the dynamic behavior of the converter.

The dataset includes measurements collected under both nominal and faulty operating conditions. A total of 48 operating categories are represented, corresponding to one healthy operating mode and 47 fault conditions. The simulated faults include grid disturbances, DC-bus abnormalities, semiconductor failures, harmonic distortion, electrical noise, voltage deviations, frequency variations, phase-sequence alterations, short-circuits, and disconnection events.

To improve dataset diversity and reduce phase-dependent bias, fault injection was performed at randomly selected temporal instants during converter operation.

Included Measurements

This repository contains the following measurement categories:

id_mea = 10 — Three-Phase RMS Voltages

Three-dimensional measurement composed of the RMS values of the three grid voltages. This low-dimensional representation characterizes the global electrical operating condition of the converter and the grid.

Dimensions: 3

id_mea = 3 — Instantaneous DC Voltage and Current

High-dimensional instantaneous measurements containing the DC-link capacitor voltage and input current sampled at switching frequency. The resulting vectorized representation captures transient and dynamic behaviors associated with fault conditions.

Dimensions: 40

id_mea = 2 — Instantaneous Three-Phase Currents

High-dimensional vectorized representation of the three-phase grid currents sampled at switching frequency. The me
