The invention relates to an interface method for an FPGA sub network and an electromagnetic transient simulation sub network. The interface method comprises the steps of enabling the FPGA sub network and the electromagnetic transient simulation sub network to be equivalent into interface equivalent circuits respectively; in a FPGA sub network simulation moment, replacing the electromagnetic transient simulation sub network by the interface equivalent circuit; solving the FPGA sub network including the equivalent circuit through an electromagnetic transient method to obtain internal voltage and current of the FPGA sub network; in a simulation moment of the electromagnetic transient simulation sub network, replacing the FPGA sub network by the interface equivalent circuit; solving the electromagnetic transient simulation sub network including the equivalent circuit through the electromagnetic transient method to obtain internal voltage and current of the electromagnetic transient simulation sub network. By adoption of the interface method, the FPGA system and the electromagnetic transient simulation system can be interlinked to perform hybrid real-time simulation calculation of different precision requirements; and the non-suddenly-changed state variables in disturbance can be fully utilized to avoid loss of interpolated value precision caused by direct interpolation of suddenly-changed electrical quantities, so that the overall precision of the FPGA and the electromagnetic transient simulation joint simulation system is improved.
Description
technical field [0001] The invention relates to an interface method in the field of electromagnetic transient simulation, in particular to an interface method between an FPGA subnet and an electromagnetic transient simulation subnet. Background technique [0002] For the local small-step simulation in large-scale simulation, due to the widespread use of VSC, its influence on the power system has been continuously expanded, and the characteristics of the power system have also changed. Multiple VSCs affect the power system through coordination and control, and the mutual influence between VSCs cannot be studied independently. Therefore, it is inevitable to use relatively real large-scale power systems for simulation research. [0003] The core idea of the electromagnetic transient method is to discretize the independent components into an equivalent branch of conductance and parallel current source, and then establish the node voltage equation of the whole network to solve...
