Abstract: A simulation technology of primary and secondary equipment integration in distribution network based on RTDS was proposed. Firstly, the basic requirements and overall framework of the primary and secondary equipment integration simulation system for distribution network were described, and the overall design method of the simulation system was given. Then, from the aspects of data acquisition, interface, conversion and algorithm selection of primary and secondary equipment, the specific implementation method of the simulation system was proposed. An example of relay protection in distribution network was simulated by using the proposed simulation system, the response time of the whole simulation system 2~3 simulation steps, which verified the feasibility and validity of the proposed primary and secondary equipment integration simulation technology.

Key words: distribution network, primary and secondary integration, RTDS, interface design, simulation technology
