Abstract

Aiming at the problems that the verification time of relay protection devices in smart substations is much longer than the planned power outage time

the workload of verification is large

and the training period of related technical personnel is long

this paper designs a remote intelligent test method for relay protection of smart substations based on autonomous controllable technology. The overall architecture and network architecture of the system are given. Without changing the original network and configuration in the station

one or more dedicated in-station test terminals are deployed to access the process layer and station control layer. The DL/T 860 protocol rules

complex event processing algorithms and alarm correlation analysis engine mechanism process the alarm information generated during the action of relay protection

and propose the remote intelligent simulation test process of relay protection

"one-click" protection simulation test technology and the remote testing technology and method of protection configuring parameters. The correctness of sampling and the integrity of the secondary circuit are verified by using the remote intelligent test method of relay protection of smart substation.
