Smart meter collecting function based remote inspection method for power outage fields

Abstract

The invention discloses a smart meter collecting function based remote inspection method for power outage fields. The method comprises steps as follows: Step 1, finding out supply transformers in transformer areas where repair requesting users corresponding to a power outage failure repair requesting work order are located as well as users of same groups in meter boxes where the users are located on the basis of a low-voltage power grid topology structure; Step 2, collecting active power values of smart meters of the repair requesting users, active power values of smart meters of the users of the same groups as well as active power values of smart meters on low-voltage sides of the supply transformers in the transformer areas where the repair requesting users are located; Step 3, analyzing collection results in Step 2, and diagnosing areas where failure sources are located. The method has the benefits as follows: the method is convenient to operate, reliable in result, quick and effective, a lot of defects of power supply enterprises in the aspect of field inspection of distribution network power outage failures are overcome, field conditions are known quickly, the failure sources are diagnosed efficiently, repairers are assisted in positioning failure points quickly and performing repair smoothly after arriving at the power outage fields, and the failure repair efficiency and the distribution network power supply stability are improved.

Description

technical field [0001] The invention relates to a remote survey and analysis and diagnosis method, in particular to a remote survey method at a power outage site based on a smart meter calling and testing function, and belongs to the technical field of power grid survey and diagnosis. Background technique [0002] With the current pace of smart grid construction, the coverage of distribution automation systems is increasing day by day. When a power outage occurs in the distribution network, relevant personnel for distribution network operation and inspection will conduct on-site investigation of the fault, find out the fault point, formulate a repair plan, and then organize the implementation of the repair work. [0003] However, the troubleshooting of the fault point mainly relies on the power distribution equipment operator to manually inspect the entire distribution line, and then perform emergency repairs after inspecting the fault point to restore power supply to users ...

Problems solved by technology

[0003] However, the troubleshooting of the fault point mainly relies on the power distribution equipment operator to manually inspect the entire distribution line, and then carry out emergency repairs after the fault point has been inspected to restore power to users in the fault area. However, the length of a 10kV distribution line is generally Above 2km, the inspection time is half an hour or even longer, which leads to the delay of follow-up repair work, affects the power supply recovery of users in the fault area, and brings direct or indirect economic losses; for important power users, the loss is especially large

[0004] Moreover, the existing on-site survey methods are easily affected by force majeure factors such as road traffic conditions and weather, which delay the arrival at the site, resulting in prolonging the entire repair cycle; during the peak period of fault repairs, the workload of on-site surveys increases sharply, which easily affects the arrival at the site. timeliness
