Research on general relay protection auto-test system software

This paper designs one kind of software architecture for general remote relay protection auto-test system. It is based on relay protection test principle and requirement on working site, and modern computer software and network communication technology. It gives an example on RCS-931 high-voltage line relay protection and RCS-978 transformer relay protection, explains the system's design ideology and working flow, and fully embodies the entire thinking of modern relay protection testing and automation control. It's proved in practice that this software can be used to most kinds of line and transformer relay protection's fixed set point auto-testing remotely, and can be extended to fulfill more flexible requirements.
