摘　　要：有源配电网暂态实时仿真需要较强的计算能力作为支持,因此提出基于现场可编程门阵列的有源配电网暂态实时仿真中系统级并行、模块级并行以及底层并行的多层级并行架构,并研究了各层级并行的实现方式。利用模块级并行以及底层并行的设计思想,使用Verilog HDL语言开发了基于浮点数运算的配电网暂态实时仿真系统。为验证该实时仿真系统的有效性,选取典型配电网络并以2?s的仿真步长进行了实时仿真测试,充分验证了所提配电网暂态实时仿真系统在仿真速度、仿真规模方面的优势,通过与Matlab/SimPowerSystems的计算结果进行比较,验证了该系统的仿真精度。Real-time transient simulation for active distribution network requires very high computational capability. This paper proposed multi-level parallel architecture of real-time transient simulator for active distribution system based on field-programmable gate array （FPGA）, involving system level, module level and elementary level. A real-time simulator for distribution system considering module level and elementary level parallelism was proposed. The simulator was designed by Verilog hardware description language and based on floating-point arithmetic calculation. In order to validate the developed simulator, a typical distribution network was simulated in the real-time simulator using a time-step of 2μs, which fully demonstrated the advantages of the simulator on execution speed and simulation scale. The simulation results show great coherence with the offline simulation in Matlab/SimPowerSystems.
