Sentence examples for fault phase from inspiring English sources
Seven separate classifiers are designed for fault phase identification for A1, B1, C1, A2, B2, C2 and G. From fault phase identification module faults are classified.
Input given to the fault phase identification and fault classification module is the fundamental component of three phase current signals and zero sequence currents of both the circuits.
The ART identifies the nature of the fault, transient or a permanent fault, and determines the fault persistence time of a transient fault by analyzing the harmonic of the fault phase voltage using wavelet packet transform (WPT).
Simulation results verify the concluded variation rules and validate the effectiveness of the proposed fault phase recognition method, which ensures exact recognition of faulty phase in asymmetrical network and high-resistance ground fault condition.
Fault classification module has two networks one for fault phase identification and one for ground identification.
Total fault samples taken for fault phase identification are 4089 and corresponding to the input samples target is assigned.
Simulations are carried out for various power system events, such as forward side fault, reverse side fault, fault with different SIR value, voltage zero and voltage peak fault, close-in fault, phase-to-phase fault, ground fault, high resistance fault, end zone fault etc.
According to the MMC-HVDC system state Eq. (7), common types of fault, e.g. phase A to ground fault, phase-AB to ground fault, three phase to ground fault are simulated based on the 61-level MMC-HVDC system using Matlab/Simulink and RT-LAB.
In some of the ANN based directional relaying techniques the fault types and the fault phases haven't been classified [37 39].
Assuming that the active power in Fig. 4 flows from (dot{E}_{1}) to (dot{E}_{2}), if k is closer to (dot{E}_{2}) than m, the pre-fault phase of (dot{U}_{kAB}) lags behind that of (dot{U}_{mAB}).
Continuing to assume that the active power in Fig. 4 flows from (dot{E}_{1}) to (dot{E}_{2}), if bus m is closer to (dot{E}_{2}) than bus k, the pre-fault phase of (dot{U}_{kAB}) leads that of (dot{U}_{mAB}).
