500KV双极
直流输电比起交流输电更适合进行远距离高压输电,基于PSCAD电磁暂态仿真软件构建了交流系统、换流变圧器、换流器、交-直流滤波器、平波电抗器及直流输电线路等的仿真模型,并以此搭建了500kV高压直流输电系统仿真模型,验证了该模型的准确性。(DC transmission is more suitable for long-distance transmission than AC transmission, the electromagnetic transient simulation software PSCAD is built based on the simulation model of AC system, converter transformer, voltage converter, AC / DC filter, smoothing reactor and DC transmission lines, and to build a 500kV HVDC system simulation model validation the accuracy of the model.)

IGBT逆变器采用SPWM技术power_3level
该模型是对50kW、380V、50Hz三相三电平逆变器的两个相同电路进行建模。IGBT逆变器采用SPWM技术,(8kHz载频)将直流电源从a +/-200Vdc源转换为220V AC, 50Hz。逆变器通过75kVA 220/380V变压器输入50kW电阻负载。变频器输出采用L-C滤波器滤除主要产生于8kHz开关频率倍数(Fh=n*8000 +/-k*50Hz)附近的谐波频率Fh。逆变器所需的12个逆变脉冲由PWM发生器块产生。该系统以恒定的调制指标在开环中工作。
电路1使用三电平桥块对逆变器进行建模。电路2使用独立的IGBTs和二极管块。用开/关延时块模拟死区,仅在电路1上应用。(It is easy for us)
