Parallel communication method of active distribution network real-time simulator based on multi-fpga

Abstract

The invention discloses a parallel communication method for an active power distribution network real-time simulator on the basis of a multi-FPGA (Field Programmable Gate Array). The method comprises the following steps that: 1) downloading each piece of subsystem information into a corresponding FPGA; 2) setting that a simulation moment t is equal to 0, and starting simulation; 3) forwards propelling simulation time for one step, wherein t is equal to t+[Delta]t; 4) beginning to carry out interaction simulation on interface data by each FPGA, and meanwhile, beginning to finish simulation calculation; 5) writing the received simulation interface data into a data memory by each FGPA; 6) carrying out simulation finishing checking on the real-time simulator; 7) judging whether physical time achieves simulation time t or not, if the physical time achieves the simulation time t, entering next step, and otherwise, entering the next step after the real-time simulator is standby to t; and 8) judging whether the simulation time t achieves a set simulation finishing moment or not, if the simulation time t achieves the set simulation finishing moment, stopping simulation, and otherwise, returning to the 3). By use of the parallel communication method adopted by the invention, the simulation speed of the parallel communication method for the active power distribution network real-time simulator on the basis of the multi-FPGA is improved, and a foundation is laid for realizing the real-time simulation of the large-scale active power distribution network on the basis of the multi-FPGA.
