VLSI Architecture for Exciter, Governor, and Stabilizer in Fast Power System EMT Simulation
Additional Document Info
2018 IEEE. In the modern power system, fast and accurate simulation tools are needed for transient analysis such as electromagnetic transients program (EMT). In our previous paper, we proposed a computational framework to model, convert, and accelerate the grid-level EMT simulations based on full custom VLSI (very large scale integration) techniques that runs orders of magnitudes faster than software or FPGA approaches. However, due to the complexity of exciters, power system stabilizers and governors, these components were omitted and the corresponding values are assumed to be constant. In this paper, we propose an efficient VLSI architecture for exciters, power system stabilizers and governors, and implement the architecture using the 45nm process. Circuit simulation results show that the proposed VLSI circuits can solve the system significantly faster than real time without sacrificing accuracy.
