利用MTDC网络放电振荡固有频率的故障测距
Fault Location Using the Natural Frequency of Oscillation of Current Discharge in MTdc Networks
摘要：
本文讨论了一种新的单端测距方法。故障定位考虑了电路参数的自然耗散。本文建立了输电线路电流振荡的阻尼固有频率与故障测距的关系。混合直流断路器（dcCB）中断故障电流，并且在没有任何驱动电压源的情况下线路电流衰减。线路电容以特定的振荡频率和衰减率向故障放电。利用这些信息，可以预测多端直流（MTdc）网络中的故障位置。MTdc的三端径向模型用于使用电力系统计算机辅助设计（PSCAD）/包括直流的电磁暂态（EMTdc）对所提出的方法进行性能评估。
英文摘要：
This paper discusses a novel fault location approach using single ended measurement. The natural dissipation of the circuit parameters are considered for fault location. A relationship between the damped natural frequency of oscillation of the transmission line current and fault location is established in this paper. The hybrid dc circuit breaker (dcCB) interrupts the fault current and the line current attenuates under the absence of any driving voltage source. The line capacitance discharges into the fault at a specific frequency of oscillation and rate of attenuation. Utilizing this information, the fault location in a multi-terminal direct current (MTdc) network can be predicted. A three terminal radial model of a MTdc is used for performance evaluation of the proposed method using Power System Computer Aided Design (PSCAD)/Electromagnetic Transients including dc (EMTdc).
