dSPACE Electrical Power Systems Simulation Package包

对Simscape Electrical™开发的电力电子电路轻松进行实时仿真

dSPACE 的 Electrical Power Systems Simulation Package 包可实时仿真 Simscape Power Systems™ (Specialized Power Systems)中开发的电气模型。

应用领域

Electrical Power Systems Simulation (EPSS) Package可实时仿真 Simscape Electrical™ (Specialized Power Systems)中开发的电气模型。该软件包能够通过多种方式集成dSPACE硬件在环环境中的Simscape Power Systems™(Specialized Power Systems)模型,例如:

  • 充电站
  • 车载充电器
  • 直流转换器
  • 整流器和逆变器
  • 风能/太阳能转换器
  • 电力工业系统
  • 智能电网


基于FPGA的方法包括根据给定的Simscape Electrical™(Specialized Power Systems)模型配置即用型的FPGA应用程序。这实现了低延迟HIL仿真。使用基于处理器的方法,可以使用扩展库来修改Simscape Electrical™ (Specialized Power Systems)模型,能够通过Simulink Coder™在dSPACE实时处理器上生成实时代码。

主要优点

对于基于 FPGA 的仿真,可以使用预先配置的 FPGA 应用程序轻松集成,不必进行耗时的 FPGA 合成。特别是不需要任何特定于 FPGA 的软件。对于基于处理器的仿真,可以为电力电子的桥式电路使用平均值模型,以确保精确仿真电力半导体的开关器件。库功能易于集成多速率系统,有助于避免干扰。

这两种仿真都通过预先计算模型的状态加快了仿真速度。由于支持模型分离(模型拆分),该仿真包可以让您同时使用多个 dSPACE 实时平台进行计算。通过集成范围功能可以捕获FPGA钟速内的高频信号。
