Description

technical field [0001] The invention relates to the technical field of power system stability analysis, in particular to an RTDS and RTLAB interconnection simulation method and system based on optical fiber communication. Background technique [0002] As the domestic power grid system becomes larger and larger, the type, scale and scope of equipment in the system become wider and wider, and the requirements for the hardware and software of the real-time simulator are getting higher and higher. A single simulator and simulation software can no longer meet the accuracy requirements for real-time simulation of large power grids. On the one hand, since the hardware of the mainstream real-time simulators on the market is RTDS and RTLAB, and the software is RSCAD and OPALRT, considering the ease of use and scope of application of the two softwares, the operation dispatching department usually uses AC transmission Line and large power grid models are built in RSCAD, and new energy...

A single simulator and simulation software can no longer meet the accuracy requirements for real-time simulation of large power grids

On the one hand, since the hardware of the mainstream real-time simulators on the market is RTDS and RTLAB, and the software is RSCAD and OPALRT, considering the ease of use and scope of application of the two softwares, the operation dispatching department usually uses AC transmission Line and large power grid models are established in RSCAD, and new energy manufacturers and converter manufacturers usually build real-time simulation models in OPALRT, resulting in the separation of large power grid and new energy power electronic converter simulation models

On the other hand, when establishing real-time simulation research on new energy access to flexible HVDC projects, the mutual migration of models between platforms becomes particularly difficult, especially when equipment manufacturers or converter manufacturers already have Mature model technology, the cost of rebuilding this model on another platform will be greatly increased, which is not conducive to the development of the industry
