Abstract

Abstract: In view of the real-time simulation requirements of large-scale complex systems such as power electronics, a hidden dragon real-time(HDRT) simulation system was developed. The strict time constraints of simulation tasks were guaranteed based on a resource-dedicated real-time scheme, supporting fixed-step and multi-rate simulations from the second level to the hundred-nanosecond level. A hybrid CPU-field programmable gate array(FPGA) architecture was adopted to accelerate computation. The system could utilize multiple simulators for parallel simulation and realized microsecond-level real-time data interaction between simulators through a dedicated PCIe switch. A single simulator could be expanded through I/O interface equipment, supporting a maximum input or output of more than 1 500 channels of real-time analog signals or more than 3 000 channels of real-time digital signals. Test results indicate that the synchronization time of a single I/O interface equipment in the HDRT simulation system is only 40 ns, indicating the characteristic of fast synchronization among I/O interface equipment; the maximum jitters of the actual simulation steps of the master and slave simulation tasks do not exceed 180 ns and 400 ns, respectively; based on tests of actual simulation models, the results demonstrate that the HDRT simulation system possesses the real-time simulation capability for large-scale complex systems.
