The invention discloses a method for judging that the energy supply intensity exceeds a limit value. The method comprises the following steps: at least one judging threshold value of a metering deviceis set to judge the data of a master station of an energy metering management system: when the energy supply intensity of the metering device is greater than the product of a standard energy supply intensity and a first threshold value; Or when the energy supply intensity of the metering device is greater than the product of the standard energy supply intensity and the second threshold value andnot greater than the product of the standard energy supply intensity and the first threshold value; Or when the energy supply intensity of the metering device is greater than the product of the standard energy supply intensity and the fourth threshold value and not greater than the product of the standard energy supply intensity and the third threshold value; Or when the energy supply intensity ofthe metering device is greater than the product of the standard energy supply intensity and the fifth threshold and not greater than the product of the standard energy supply intensity and the fourththreshold; It is determined that the energy supply intensity exceeds the limit.
