Development of Electrical and Network Test Tool for IEC 61850 Based Power System Protection

Abstract

IEC 61850 standard for communication networks and systems allows the implementation of applications such as distributed metering, control, and teleprotection in the power grid. The use of this technology, however, demands conformity tests in the configuration of Intelligent Electronic Devices (IEDs) and their protection schemes. These tests depend on the artificial and controlled generation of electrical signals as well as injection of synchronized packets in the communication network. This work proposes a low-cost and open-source tool, which presents the required features for testing protection schemes based on IEC 61850. The results show that our tool can follow progressive transmission intervals of GOOSE messages. Moreover, it can test protections schemes by synchronizing message and signal injections in the system.
