In this paper, an effective method for fault detection and classification in a double-circuit transmission line compensated with TCSC is proposed. The mutual coupling of parallel transmission lines and presence of TCSC affect the frequency content of the input signal of a distance relay and hence fault detection and fault classification face some challenges. One of the most effective methods fo...

In this paper, a new algorithm has been proposed for determining accurate fault distance on multi-terminal transmission lines. This method is based on genetic algorithm, and uses synchronous data recorded at all terminals, and includes two steps. In the first step, employing a comparing method, the faulty section is identified. In the second step, precise distance of the fault is found utilizin...

In this paper a novel pulse sequence testing methodology is presented [22] as an alternative to Time Domain Reflectometry (TDR) for transmission line health condition monitoring, faultfinding and location. This scheme uses Pseudo Random Binary Sequence (PRBS) injection for transmission line testing and fault location with cross correlation (CCR) techniques to build a unique response profile, as...

distinguishing the susceptible areas to landslide using different landslide susceptibility mapping (lsm) models is one of the primitive and basic works to reduce probable damages and reduce risk. the main purpose of this research is the efficiency evaluation of four methods including information value (winf), valuing area accumulation (wa), analytical hierarchy process (ahp), kopta-joshi propos...

This paper presents a new distance relay technique for transmission line protection by using well known control technique; Adaptive Neuro-Fuzzy Inference System (ANFIS). The ANFIS can be viewed either as a fuzzy system, a neural network or fuzzy neural network FNN. The structure is seen as a neural network for training and a fuzzy viewpoint is utilized to gain insight into the system and to sim...

The STATCOM (Synchronous Static Compensator) based on voltage source converter (VSC) is used for voltage regulation in transmission and distribution systems. The STATCOM can rapidly supply dynamic VARs required during system faults for voltage support. The apparent impedance is influenced by the reactive power injected or absorbed by the STATCOM, which will result in the under reaching or over ...

Analytical solution for the problem of a surface-breaking long strike-slip fault in an elastic layer overlying an elastic half-space is well known. The purpose of this note is to obtain the corresponding solution for a blind fault. Since the solution is valid for arbitrary values of the fault-depth and the dip angle, the effects of these two important fault parameters can be studied numerically...

Research on fine tuning stabilization properties has received attention for more than a decade. This paper presents probabilistic algorithms for fault containment. We demonstrate two exercises in fault containment in a weakly stabilizing system, which expedite recovery from single failures, and confine the effect of any single fault to the constant-distance neighborhood of the faulty process. T...
