Generalized method for fault simulations in power systems
European Transactions on Electrical Power, 2000AbstractThis paper presents a new generalized method of modelling of any kind of shunt and series faults as single or simultaneous faults in arbitrary combination. The proposed approach can be used for conventional fault studies for the steady‐state model based on the nodal admittance representation as well as for fault simulations under transient ...

Wind turbine power generation performance evaluation under faults condition
2016 International Conference on Condition Monitoring and Diagnosis (CMD), 2016Since faults in wind turbine transmission chains would reduce the efficiency of generated power, accurate power generation performance (PGP) evaluation is necessary for the economic use of wind energy and reasonable arrangement of maintenance plan. However, the harsh environment and illegal operations lead the PGP difficult to evaluate.

Location of faults in power cables by fault-generated surges
2012The object of this research is to develop a satisfactory method for locating high-impedance faults in underground cables. Most methods of locating faults require that the fault-impedance be reduced to a low value before the measurement can be made. After a careful investigation of the available literature, it was decided that the most desirable method ...

PLL algorithm for power generation systems robust to grid voltage faults
2006 37th IEEE Power Electronics Specialists Conference, 2006In the case of unbalanced grid faults, one of the main problems for the Distributed Power Generation Systems (DPGSs) controller is the second harmonic ripple in the control, consequence of the phase unbalance caused by the fault. The second harmonic propagates into different sections of the controller and can have a negative influence on the controller

Independent PQ Control for Distributed Power Generation Systems under Grid Faults
IECON 2006 - 32nd Annual Conference on IEEE Industrial Electronics, 2006This work aims to present a generalized vector-based formulation for calculating the grid-side current reference of distributed power generation systems in order to independently control active and reactive power delivered to the grid. Strategies for current reference generation were implemented on the abc stationary reference frame and their ...

High power-density fault-tolerant PM generator for safety critical applications
2013 International Electric Machines & Drives Conference, 2013Many safety-critical applications especially in aviation require high power (mass) density generators with high reliability. While PM machines promise significant improvements in power density, and reliability, the widespread use of permanent magnet (PM) generators has been hitherto limited by the potentially detrimental effect of internal machine ...

A General Approach for Fault Identification in SOFC-based Power Generation Systems
2018 Annual American Control Conference (ACC), 2018The design of fault identification method in fuel cells(FCs)-based systems remains a key challenge. This paper proposes a general data-based fault identification method using deep learning(DL). Because of the great success of deep learning in a variety of practical applications, it has recently become the most popular approach in machine learning. Deep
