考虑“风能-机械能-电能”全过程耦合的风电场精细化高效仿真将面临仿真对象多、仿真规模大、仿真步长小的挑战。为此,基于中央处理器(CPU)、图形处理器(GPU)、现场可编程门阵列(FPGA)异构计算芯片设计仿真平台架构,以实现仿真对象与硬件特性的匹配;其次,在操作系统底层对基于CPU的仿真设备进行实时性改进,以兼顾大规模和小步长仿真需求;最后,针对高效离线仿真需求,基于并行计算技术,设计了高效仿真计算内核和引导式仿真建模软件。基于含40台机组的风电场仿真算例对所提出的仿真技术进行测试。结果表明,所提出的仿真技术在计算效率和实时性方面均能够满足风电场精细化高效仿真需求。
The refined and high-efficiency simulation of wind farms
considering the full-process coupling of “wind energy-mechanical energy-electrical energy”
faces challenges including multiple simulation objects
large simulation scale
and small simulation step size. To this end
the simulation platform architecture is designed based on the heterogeneous computing chips of the central processing unit (CPU)
graphics processing unit (GPU)
and field-programmable gate array (FPGA)
to realize the matching between simulation objects and hardware characteristics. Secondly
the real-time improvements are made for CPU-based simulation equipment at the bottom layer of the operation system
so as to consider the large-scale and small-step-length simulation demand. Finally
to meet the high-efficiency offline simulation demand
the high-efficiency simulation computing kernel and the bootstrap simulation modeling software are designed based on the parallel computing technology. The proposed technology is tested based on a wind farm simulation case with 40 wind turbines. The results show that the proposed simulation technology can meet the demand for refined and high-efficiency simulation of wind farms in terms of computation efficiency and real-time performance.
