PVM3による電力変換システムの周期定常解析の並列化処理法 Parallel Processing of Steady-State Analysis for a Power Electronic System by PVM3
It is important to get a steady-state operation of a power electronic circuit for its design. The shooting method, which is one of steady-state analysis methods, solves a boundary value condition which equates initial values to final values after one-period transient. This paper proposes how to process the analysis in parallel by using a Parallel Virtual Machine (PVM3) system. Especially the multiple shooting method (MSM) which divides the shooting time into subsections is suitable because it can parallel numerical processes for the divided shooting times by using multiple CPU units indepandently. This parallel method is applied to converter examples which are processed by PVM3. The computed results are investigated for their convergence and CPU times to check their parallel effects. According to the MSM algorithm, CPU times are reduced almost to 1/5 by using 5 computer units from a PVM3 system example.
