Abstract
Electromagnetic transient (EMT) simulation of power systems is widely applied in the planning, design, and operation of modern grid. However, large-scale real-time EMT simulation requires significant computational power and is difficult to achieve small simulation timestep. A field-programmable gate array (FPGA)-based configurable EMT emulation system is proposed in this paper. A parallel nodal algorithm with pipelined double-precision floating-point calculation is designed to achieve high accuracy and small timestep. In addition, a novel nodal equation calculation (NEC) structure is designed to save area and latency. Moreover, the NEC module is reused to merge the nodal current vectors, which further improves the emulation scale of the system. The proposed real-time EMT emulation system on FPGA achieves a timestep of 2us and can emulate a configurable power network up to 74 nodes.
