Problems solved by technology
[0002] In the current power grid, there are more and more devices containing power electronic devices such as thyristors and insulated gate bipolar transistors. However, when using pure software electromagnetic transient programs to simulate these high-frequency switching elements, the step size is too large to accurately simulate. Component characteristics, the step size is too small and cannot be real-time, and the contradiction is difficult to reconcile

Embodiment Construction
[0029] The present invention will be described in further detail below in conjunction with the accompanying drawings.
[0030] The small-step real-time simulation system and the large-step real-time simulation system jointly complete the simulation calculation. The large-step real-time simulation system undertakes large-step simulation tasks, and its simulation step is usually 50us. FPGA needs to undertake higher real-time requirements, and small-scale subnetworks have small-step electromagnetic transient simulations, and the simulation step size is 2us. The data required for system simulation is generated by the large-step real-time simulation system, so the large-step real-time simulation system needs to send all the initialization data required for small-step simulation to the FPGA through optical fiber and store them in the FPGA local memory. The initialization data includes parameter information of each component, circuit topology, conductance inverse matrix, etc. The c...

Description
technical field [0001] The invention belongs to the technical field of power system simulation, in particular to an FPGA-based small-step real-time simulation system. Background technique [0002] In the current power grid, there are more and more power electronic devices including thyristors and insulated gate bipolar transistors. However, when using pure software electromagnetic transient programs to simulate these high-frequency switching elements, the step size is too large to accurately simulate. Component characteristics, the step size is too small and cannot be real-time, and the contradiction is difficult to reconcile. One of the solutions is to use hardware to realize these small-step calculations, and at the same time, it is mixed with the large-step simulation of conventional electromagnetic transient software. The FPGA hardware system designed by this patent achieves this goal well; [0003] Advanced Digital Power System Simulator (ADPSS for short) is an all-dig...
