Photovoltaic fault dataset
This dataset contains 16 days of operational data from a grid‑connected photovoltaic power plant, covering both normal and fault conditions. It consists of two .mat files that can be loaded with MATLAB and includes voltage, current, temperature, irradiance, and fault‑type labels.

dataset_elec.mat: DC electrical data (voltage and current for two strings)dataset_amb.mat: Temperature, irradiance, and fault‑type labels
Variable Description
| Variable | Description |
|---|---|
| vdc1 | Voltage – String 1 |
| vdc2 | Voltage – String 2 |
| idc1 | Current – String 1 |
| idc2 | Current – String 2 |
| irr | Irradiance |
| pvt | Photovoltaic module temperature |
| f_nv | Fault label |
Fault Labels (f_nv)
| Value | Description |
|---|---|
| 0 | Normal operation (no fault) |
| 1 | Short circuit (short between two modules in a string) |
| 2 | Degradation (resistance between two modules in a string) |
| 3 | Open circuit (a string disconnected from the inverter) |
| 4 | Shadow (one or more modules covered by shadow) |
Fault Introduction Methods
- Degradation: introduced by inserting a resistive load bank between two modules.
- Short circuit: introduced by connecting a cable between the positive and negative terminals of the modules.
- Open circuit: introduced by opening the main breaker of the string.
- Shadow: occurs naturally, caused by nearby buildings.
