What is FPGA-Based Real-Time Emulation?
FPGA-Based Real-Time Emulation uses field-programmable gate arrays to implement hardware description language models of power systems for microsecond-resolution simulation and closed-loop control.
This subtopic targets FPGA implementations for emulating power converters, electric machines, and networks with parallelism optimizations. Key works include multi-FPGA designs achieving large-scale electromagnetic transient simulation (Chen and Dinavahi, 2013, 84 citations). Approximately 10 high-impact papers from 2009-2023 address FPGA hardware-in-the-loop methods.
Why It Matters
FPGA emulation enables microsecond real-time testing of HVDC systems beyond CPU capabilities, as shown in MMC-HVDC simulations (Ou et al., 2014, 86 citations). It supports hardware-in-the-loop validation for power electronics and smart grids (Lauss and Strunz, 2020, 70 citations). Applications include aircraft power distribution frequency-response measurements (Roinila et al., 2018, 71 citations) and large-scale power system analysis (Faruque et al., 2015, 468 citations).
Key Research Challenges
Large-Scale Parallelism
Multi-FPGA designs demand efficient partitioning for detailed electromagnetic transient models (Chen and Dinavahi, 2013). Synchronization across FPGAs limits scalability in real-time power system emulation. Functional decomposition addresses communication overhead.
Microsecond Stability
Achieving stable closed-loop performance requires precise power interface modeling (Lauss and Strunz, 2020). Numerical stability in FPGA solvers challenges HIL simulations of integrated power electronics. Interface algorithms mitigate stability issues.
HDL Model Optimization
Optimizing Verilog/VHDL for FPGA parallelism constrains model fidelity in power converters (Ou et al., 2014). Balancing computation speed and accuracy poses design trade-offs. Automated code generation aids deployment.
