Method for monitoring tripping of distribution network line

The invention provides a method for monitoring tripping of a distribution network line. The method comprises the steps that step 100, real-time load of the distribution network line is sampled at the time t; step 200, de-noising processing is conducted on a real-time load sampling result, wherein it...

Summary:The invention provides a method for monitoring tripping of a distribution network line. The method comprises the steps that step 100, real-time load of the distribution network line is sampled at the time t; step 200, de-noising processing is conducted on a real-time load sampling result, wherein it is considered that the real-time load is effective load when the real-time load sampling result is smaller than or equal to a first threshold value T; step 300, the effective load considered in the step 200 is used for updating an effective load set; step 400, the real-time load change rate and the real-time load change speed are calculated; step 500, the real-time load serves as the real-time load sampling result and the step 100 is repeated if the absolute value of the real-time load change rate is smaller than a second threshold value and the absolute value of the real-time load change speed is smaller than a third threshold value, and if not, the step 600 is executed; step 600, alarm display information is sent to prompt tripping of the distribution network line.
