Referring to fig. 1, fig. 1 is a schematic structural diagram of an electromagnetic transient real-time simulation apparatus provided in an embodiment of the present application, the apparatus includes a grid-level simulation module, a station-level simulation module, and a unit-level simulation module, and each simulation module is described below.
The unit-level simulation module is formed based on a first FPGA set, the first FPGA set is composed of a plurality of first FPGA modules, each first FPGA module is composed of a plurality of interconnected FPGAs, and the first FPGA set is used for realizing real-time simulation with small step length of less than 5 microseconds.
Further, the step size of the real-time simulation of the first FPGA set may be any step size in a range of 0.5 microseconds to 5 microseconds.

wherein, C unit Can be the simulation scale of the unit-level simulation module, n can be the number of the first FPGA module, a unit-i The number of interconnected FPGAs in the ith first FPGA module can be C FPGA It can be a single FPGA simulation scale.
Because the unit-level simulation module can realize simulation of any step length within the range of 0.5 microsecond to 5 microseconds, the refined simulation requirement of a novel power system can be met.
