The invention relates to an achievement method of operation, maintenance, display and control of the health states of a photovoltaic power station. The method is based on the photovoltaic power station and an operation and maintenance system, wherein the photovoltaic power station comprises a photovoltaic panel, an inverter and a combiner box. The method comprises the steps that a monthly display interface is built; the date of a day is detected; the health state of the photovoltaic power station on the day is detected; a timing program is adopted, and in a system default time, the detected health state of the photovoltaic power station on the day is analyzed; the analysis result of the health state of the photovoltaic power station on the day is recorded, wherein the recording format is a daily display data chart; according to data in the display data chart, a corresponding legend is generated; the legend is put in the monthly display interface matched with the date of the day; the above steps are repeated every day to conduct a monthly record. By means of the method of operation, maintenance, display and control of the structure, the monthly health states of the photovoltaic power station are convenient to observe visually, the health states of the power station in a period are better understood, and timely maintenance is convenient.
