摘　　要：随着配电网技术的发展,有源配电网及其数字仿真技术受到越来越多的重视。现场可编程门阵列(field-programmable gate array,FPGA)具有高度硬件并行结构、资源丰富、运行频率高、成本低等优点。面向有源配电网的仿真需求,提出基于FPGA的暂态实时仿真器的计算求解框架,并给出基本无源元件、线路、电源、断路器等多个关键功能模块的硬件实现方式。所提暂态实时仿真方法,充分利用FPGA具有的高度并行特性以及流水线结构,采用浮点数运算保证数值精度,为后续基于FPGA的有源配电网暂态实时仿真系统的进一步开发奠定了基础。With the development of distribution system, active distribution network and related digital simulation technology have drawn extensive attention. A real-time transient simulation method based on FPGA was proposed, which takes advantage of many merits of field-programmable gate array （FPGA）, such as the highly parallel structure, rich hardware resources, high operating frequency and low cost. This paper introduced the solving architecture orient to real-time transient simulation of active distribution system, as well as the FPGA realization of the device modules including passive element, line model, source and breaker. The proposed method is based on paralleled algorithm and deeply pipelined design, and uses floating-point arithmetic calculation to gain high accuracy. This paper laid the foundation for future work on real-time transient simulation of active distribution network based on FPGA.
