Prognostics and health management of photovoltaic systems
| DWPI Title: System for analyzing output of photovoltaic system and providing prognosis and health management of photovoltaic system, has modeling component to receive data associated with parameter relating to operation of photovoltaic system |
| Abstract: The various technologies presented herein relate to providing prognosis and health management (PHM) of a photovoltaic (PV) system. A PV PHM system can eliminate long-standing issues associated with detecting performance reduction in PV systems. The PV PHM system can utilize an ANN model with meteorological and power input data to facilitate alert generation in the event of a performance reduction without the need for information about the PV PHM system components and design. Comparisons between system data and the PHM model can provide scheduling of maintenance on an as-needed basis. The PHM can also provide an approach for monitoring system/component degradation over the lifetime of the PV system. |
| Use: System for facilitating analyzing an output of a photovoltaic system and providing prognosis and health management of photovoltaic system. |
| Advantage: The system comprises a modeling component to receive data associated with a parameter relating to current operation of a photovoltaic system and configured to output an anticipated operating metric relating to the parameter, and thus enables facilitating operation of the artificial neural network without going into an unnecessary alarm condition by facilitating dynamically setting and adjusting the threshold setting, and also facilitating rapid detection of photovoltaic system faults for reducing power output. |
| Novelty: The system (200) comprises a modeling component (260) to receive data associated with a parameter relating to current operation of a photovoltaic system and configured to output an anticipated operating metric relating to the parameter. An operating component (240) is configured to receive data relating to an output of the photovoltaic system during the current operation of the photovoltaic system. A comparison component (250) is configured to determine whether a difference exists between the value of the anticipated operating metric and the actual operating metric. |
