AI Technical Summary

Technical Problem

The power outage is now adopted for the transformation of intelligent substation measurement and control devices, which leads to the impact of reliable power supply, long transformation cycle, difficulty in coordination of power outage plans, affecting production and living electricity, and poses a risk of safe operation of the power grid.

Method used

Provide an online transformation method and verification platform for intelligent substation measurement and control devices without power outage. By obtaining the ICD model of the new measurement and control devices, simulate the connection to the intelligent substation, check the remote signal, telemetry, and remote control signals, generate new configuration files, and verify them on the offline platform, and finally carry out actual transformation without affecting power supply.

Benefits of technology

The online transformation of the intelligent substation measurement and control device without power outage was achieved, which shortens the transformation time, avoids the impact on power supply, and ensures the monitoring and protection of power grid equipment.

Abstract

The invention relates to an intelligent substation measurement and control device on-line transformation method and verification platform without power outage, and the method comprises the steps: obtaining an ICD model of a new measurement and control device when an old measurement and control device of an intelligent substation needs to be transformed into the new measurement and control device; simulating a new measurement and control device to access the intelligent substation according to the ICD model to obtain a new measurement and control configuration file of the new measurement and control device, a new simulation configuration file of the virtual device and a new SCD configuration file of the mirror background server; after the three remote signals are checked to be correct, a new measurement and control device is simulated to access the intelligent substation on an off-line intelligent substation measurement and control device non-power-cut online transformation verification platform, and configuration files corresponding to the new measurement and control device, the virtual equipment and the mirror image background server are obtained; the verification platform is connected to the station level network of the intelligent substation in the actual measurement and control device replacement site, and the old measurement and control device is connected to the measurement and control configuration verification module, so that the transformation time is short, the power supply is not affected, and the monitoring and protection of power grid equipment are not lost.
