Rapid replacement method in case of failure of transformer substation measuring and control device

Abstract

The invention discloses a rapid replacement method in case of a failure of a transformer substation measuring and control device. The method comprises the following steps: analyzing an IEC61850 modelof a new measuring and control device to acquire a three-remote data model, exporting a three-remote data model of the original measuring and control device from a monitoring system database, and carrying out automatic matching and generating a database point table according to mapping relationships between the data models and association types and association terminals; virtualizing the new and the original measuring and control devices into different data source channels, and establishing channel association between the data source channels and the generated database point table; and achieving rapid measuring and control device replacement through the multi-channel switching technology. The method provided by the invention has the advantages that the measuring and control device is addedthrough the additional data source channel, original monitoring system and telecontrol database configurations are not changed, and all the association is automatically achieved through programs, sothat high accuracy and reliability during database maintenance are effectively achieved, the probability of manual errors and the debugging workload are reduced, and technical guarantees are providedfor the rapid measuring and control device replacement.

Description

technical field [0001] The invention relates to the field of electrotechnical technology, in particular to a quick replacement method in the event of failure of a substation measurement and control device. Background technique [0002] With the continuous advancement of power grid construction, the number of substations as hubs is increasing, and the running time of substations is getting longer and longer. As a measurement and control device for substation data collection, its running time has approached or exceeded its service life. Risks such as reduced accuracy and unstable operation seriously affect the safe and stable operation of the power grid, and urgent transformation is needed. However, the importance of the substation determines that it is impossible to renovate all the overdue equipment without power outage. It can only be carried out in batches at intervals, which causes some substation devices to fail before they can be rebuilt in the future and need to be rep...
