电力系统实时仿真中细粒度并行实现
Implementation of Fine Granularity Parallelization in Power System Real-Time Simulation

为充分利用 FPGA 的高度并行特性，设计了一种可实现加减乘除混合运算的变结构运算组件．从实用性和 扩展性角度出发，用控制指令描述对运算组件的操作，用有向无环图描述计算任务之间的依赖关系，提出了一种新 的基于 FPGA 的仿真程序设计方法．在此基础上，以 30 , μs 仿真步长在一块 5SGSMD5 芯片上实现了 IEEE-14 电力 系统的实时仿真，其实验结果与 PSCAD 仿真结果相吻合
In order to make full use of highly parallel characteristic of FPGA，a variable-structure processing unit was designed to achieve arithmetic with the mixed operation of addition，subtraction，multiplication and divi- sion．From the perspective of practicability and extensibility，applying the control instruction to describing the opera- tion of processing unit and the directed acyclic graph to describing the process of parallel computing，a new simula- tion program design method based on FPGA was proposed．On this basis，a real-time simulation of IEEE-14 bus power system has been realized on a 5SGSMD5 chip with 30 μs time-step，and the experimental results are consistent with the PSCAD simulation results
