Problems solved by technology

The disadvantage of this single server simulator is that the number of GPUs is small. The biggest problem is also that the bandwidth of data exchange between GPU and CPU is not enough, which affects the effect of parallel simulation. Therefore, this platform is still in electromechanical transient simulation. In terms of research, it has not been seen that anyone can well realize the electromagnetic transient simulation of large-scale power systems on this platform

Abstract

The invention discloses a miniaturized super emulator for the study of transient stability of a large power system. The miniaturized super emulator comprises a plurality of cabinets, each cabinet is provided with a plurality of cases, and each case is provided with a plurality of embedded computing plug-ins. The embedded computing plug-ins in the cases are connected with a hardware back plate through a multi-needle interface, and each embedded computing plug-in is provided with a plurality of high-speed computing chips different from conventional computing chips, a plurality of FPGA chips and other necessary supporting components. The high-speed computing chips of the same embedded computing plug-in are directly connected through SPIs and other buses, the high-speed computing chips of all the computing plug-ins of the same case are connected through FPGA-hardware back plate integrated matrix system buses, and communication and data exchange among all the parts are compressed through a secondary codon algorithm. The cases carry out multiple optical fiber data communication through a CAN bus, a USB, the high-speed Ethernet and the like.

Description

technical field [0001] The invention relates to a miniaturized supercomputer, in particular to a miniaturized super simulator used for research on transient stability of a large power system. Background technique [0002] As we all know, after my country successfully developed the "Galaxy" supercomputer, it also developed the "Dawn" supercomputer. In recent years, the Tianhe-I and Tianhe-II supercomputers that were successfully developed ranked first in the world. These supercomputers are huge, and some even take up half the space of a football field, and the price is astonishing. It is very difficult for general scientific research institutes to have a supercomputer that truly belongs to them, and it is even more difficult for ordinary research groups to catch up. [0003] The Yinhe and Sugon supercomputers basically realize parallel processing by several PCs or their main boards, and the specific parallel contacts are set at the ports of the main boards. From the perspec...
