Description

technical field [0001] The invention belongs to the technical field of power system simulation testing, in particular to a stable system integration testing device and testing method based on HDLC protocol simulation. Background technique [0002] The regional security system consists of two or more station security devices. The information processing capability of a single plant station control and the processing capability of inter-station communication need to be improved with the improvement of regional control requirements. The implementation of the optical fiber communication backbone network provides good conditions for the high-speed, reliable, and large-capacity transmission of a large amount of real-time information between regions, but the existing stable equipment is still lacking in communication processing capabilities, debugging methods, and verification methods. [0003] For a power system with a simple structure, its control system is relatively simple, for ...
