摘要
Abstract
The building and simulation of main circuit of modular multilevel converter （MMC） can be completed by real time digital simulator （RTDS） under small-step environment. Due to the condition that the insufficient computing power of processors for existing RTDS cannot undertake the simulation of MMC with levels up to the amount of 200, to perform larger-scale simulation by existing computing power of RTDS processors a modeling method is proposed, namely, the MMC models of each phase are packaged individually in small-step environment, then the packaged small-step circuit models of three phases are interconnected to form a whole MMC. Contrast experiments for individually packaged MMC and integrally packaged MMC with the same scale as the former are carried out, and detailed contrast measurement of EMS at both terminals of each small-step model and that of AC and DC voltages of converter are conducted. Simulation results show that the proposed modeling method is feasible, not only the simulation capability can be enlarged, but also the electric quantities in the circuits will not be obviously affected.关键词
