高压直流输电是一种高效、成熟的长距离输电技术。然而，到目前为止，高压直流输电几乎完全局限于对等连接或对等设备之间位置较近的网络。本文介绍了一种基于平坦度的树状无周期高压直流输电网络的前馈控制设计，该网络由两个或多个换流站组成。由此产生的控制概念允许灵活地确定网络内的功率分配。此外，可以很容易地考虑到特别与长传输线相关的诸如波传播引起的功率损失和延迟之类的影响。对一个算例网络进行了数值仿真，验证了结果的有效性。
An efficient and well-established technology for power transmission across long distances is high voltage direct current transmission (HVDC). However, HVDC is up to now almost completely limited to peer-to-peer connections or networks with peers situated closely to each other. This contribution introduces the flatness-based design of a feedforward control of tree-like, i.e. cycle-free, HVDC transmission networks comprising two or more converter stations. The resulting control concept allows a flexible determination of the power distribution within the network. Furthermore, effects like power losses and delays due to wave propagation, which are related especially to long transmission lines, can be easily taken into account. Numerical simulations for an example network are included to prove the value of the results.
