Zusammenfassung:The invention provides a method, a device and equipment for monitoring the operation state of photovoltaic power station, and the method includes the following steps: calculating the energy efficiency loss of photovoltaic modules in a photovoltaic power station by using multiple linear regression model; calculating the operating cost of the photovoltaic power station by using economic analysis model; determining the fault probability of photovoltaic modules; determining the replacement time of photovoltaic modules; counting the replacement time of photovoltaic modules in different photovoltaic power stations, and adjusting the number of corresponding photovoltaic modules. In the invention, the energy efficiency loss, operating cost and fault probability are determined automatically, and the replacement time and number of photovoltaic modules are calculated, thus effectively improving the state monitoring efficiency.
