Hydropower station governor system pressure leakage detection method

The invention provides a hydropower station governor system pressure leakage detection method, and relates to the field of hydropower automation. The method comprises the following steps: S1, acquiring first air supply data of a target hydropower station governor system within a current preset duration T; s2, according to the first gas supply data, the current average gas supply interval duration and the current theoretical gas supply frequency are calculated; s3, a first correlation coefficient is determined according to the current average gas supply interval duration and a first preset threshold value, and a second correlation coefficient is determined according to the current theoretical gas supply frequency and a second preset threshold value; s4, calculating a current logic relation value of the first correlation coefficient and the second correlation coefficient according to a preset logic relation; and S5, determining the pressure leakage condition of the target hydropower station governor system acco
