The interconnection of Transmission lines forms together HVAC transmission networks. The transmission Network is named as "power grids" in the USA, while in the UK these networks is called "national grid." It is a usual practice to step up voltage above 110 kV in order to reduce the loss ...
本演示展示了一个320 kV、200 MW高压直流输电系统,该系统具有两个模块化多级变流器(MMC),将两个110 kV高压交流电网互连。MMC是用于HVDC应用的普遍类型的电压源换流器拓扑。 在高电压下,直流电的传输可以比交流电更有效。HVDC相对于HVAC的效率是其越来越多地用于配电的驱动因素。对于远离消费者的可再生能源的整合尤...
