仿真模型中，通过1000MW(5OOkv, 2kA)的直流输电线路从一个500KV、5000mva、50hz的电力系统EM向另一个345kv10000mva50hz的电力系统Ell输送电力。整流桥和逆变桥均由两个通用6脉冲桥搭建而成。交流滤波器直接接在交流母线上，它包括11次、13次和更高次谐波等单调支路。总共提供600mvar的容量。(In the simulation model, the 1000MW (5OOkv, 2kA) DC transmission line transfers power from one 500KV, 5000MVA, 50Hz power system EM to another 345kv10000mva50hz power system Ell. The rectifier bridge and the invert bridge are all constructed by two general 6 pulse bridges. The AC filter is connected directly to the AC bus, which includes 11 or 13 and higher harmonics. A total capacity of 600mvar is provided.)
