Abstract :
Real-time electromagnetic transient simulation system involves high computational tasks and is very difficult to achieve small time step. In this paper, we proposes the field programmable gate array (FPGA) design and implementation for real-time electromagnetic transient simulation system with double-precision floating-point calculation. The parallel computing and fully pipelined architecture of the electromagnetic transient program is employed to improve the processing speed. In addition, the nodal equation calculation structure is designed to achieve small time-step. The proposed system can support the simulation of power grid with up to 74 three-phase buses, including transmission line, single-phase two-winding transformer, breakers and several current and voltage sources. The implementation result on FPGA shows that the proposed electromagnetic transient simulation system reach 2 us time-step. Furthermore, the captured real-time oscilloscope results verify high accuracy of the small time-step emulation system compared to the offline simulation of the electromagnetic transient software.
