本文介绍了多端输电线路故障测距算法的开发与实现。这些算法是故障定位系统的一部分，该系统能够根据电压和电流相量正确识别故障点，这些相量是通过测量位于传输线终端上的智能电子设备的电压和电流信号计算出来的。这些算法可以访问输电线路的电气参数，以及有关变压器负载及其连接类型的信息。本文还介绍了故障测距算法所使用的电力系统元件的相分量模型的发展。
This research presents the development and implementation in a computational routine of algorithms for fault location in multiterminal transmission lines. These algorithms are part of a fault-location system, which is capable of correctly identifying the fault point based on voltage and current phasor quantities, calculated by using measurements of voltage and current signals from intelligent electronic devices, located on the transmission-line terminals. The algorithms have access to the electrical parameters of the transmission lines and to information about the transformers loading and their connection type. This paper also presents the development of phase component models for the power system elements used by the fault-location algorithms.
