Abstract

The invention belongs to the technical field of electrical equipment monitoring, and discloses a distribution network condition monitoring and pre-warning method and system. The method comprises the steps of obtaining first distribution network equipment information sent by a plurality of distribution network application systems and second distribution network equipment information collected by information collecting equipment; according to the first distribution network information and the second distribution network information, obtaining the distribution network equipment monitoring information; judging whether parameters in the distribution network equipment monitoring information exceed a preset threshold value or not, if yes, generating alarm information, and sending the alarm information to terminal equipment. According to the distribution network condition monitoring and pre-warning method and system, the problems that due to the fact that the amount of the collected distribution network equipment information is large, effective information cannot be timely obtained, and inconvenience is brought to distribution network equipment operation and management are solved. According to the distribution network condition monitoring and pre-warning method and system, the distribution network status can be monitored in real time, a fault of distribution network equipment is timely found, an alarm is given, the troubleshooting time is shortened, the distribution network equipment operation and management efficiency is improved, and safety operation of a power grid is ensured.

Description

technical field [0001] The invention belongs to the technical field of power equipment monitoring, and in particular relates to a distribution network state monitoring and early warning method and system. Background technique [0002] The power system is a huge and complex system. In the power system, there are many distribution network equipment and complex distribution network lines. When the power system fails, troubleshooting takes time and effort, increases the workload of the staff, and requires a large-scale power outage, which brings inconvenience to residents' lives. [0003] At present, in substations and power distribution monitoring and management systems, the collection scheme for the operation status information of distribution network equipment is relatively mature. bring inconvenience. Contents of the invention [0004] In view of this, the embodiment of the present invention provides a distribution network status monitoring and early warning method and s...
