Accurate Noniterative Fault-Location Algorithm Utilizing Two-End Unsynchronized Measurements

Fault Locating, Prediction and Protection (FLPPS)

“…The method's main features include: it considers line shunt capacitance, it is theoretically independent of fault resistance magnitudes (but simulation results provided in the paper show an increase in error percentage with higher fault resistance values), and it does not need any iterative load flow analysis. A.2.4.1.13 Accurate Non-iterative Fault Location Algorithm Utilizing Two-End Unsynchronized Measurements [17] Summary: This paper presents a new two-terminal impedance based fault location algorithm, which takes into account the distributed parameter line model. The algorithm utilizes unsynchronized measurements of voltages and currents from two ends of a line and is formulated in terms of the fundamental frequency phasors of symmetrical components of the measured signals.…”

Novel modified impedance-based methods for fault location in the presence of a fault current limiter

“…* Correspondence: doroudi@shahed.ac.ir These methods are more accurate than single-ended methods because of their independence from fault resistance and fault type. However, the double-ended approach requires 2 datasets: time-synchronized measured data from both the sending and receiving end terminals [13].…”

The search algorithm for optimal reliability increasing system parameters in 10 kv branched distribution networks

“…Однако, несмотря на распространённость и раз-нообразность средств, применяемых для повышения надёжности электроснабжения в линиях электропе-редачи (ЛЭП) напряжением 10 кВ, научно обоснован-ной и практически приемлемой методики, позволяю-щей осуществлять выбор оптимального количества и С целью решения данной проблемы в статьях [3,4] рассмотрены методы «двухстороннего» определения КЗ на высоковольтных ЛЭП и представлены алгоритмы, позволяющие выявлять повреждённое присоединение. А в методике [5] используется алгоритм, основанный на определении повреждённого участка с последующим уточнением расстояния до места повреждения.…”
