Digital-analog Hybrid Simulation of Large-scale AC-DC Power Grids Based on ADPSS Next-generation Simulation Platform

China’s power grid has become the one with the world’s most complex operating characteristics and most difficult controlling. Based on the ADPSS new-generation simulation platform, a large-scale AC-DC power grid digital-analog hybrid simulation system is built. This system is used in the research of the HVDC-controlled closed-loop simulation tests and AC-DC interaction analyses which has very important practical significance for improving the capacity of the simulation analysis of the main electrical quantities and the related operating data under the normal, fault, and abnormal operating conditions of the AC-DC power grid. This paper introduces the detailed scheme and the implementation methods of this technology, and verifies the correctness of the technology in this paper through the case of digital-analog mixed simulation of the 7-circuit DC control protection devices in the northwest network.
