Explicit Relations between Electrical Transient Characteristics and Structure-parameters of Superconducting Generators under Sudden Short-circuit Faults
Superconducting generators (SCGs) have many advantages as compared with conventional ones, and practical use is expected. Before practical use, it is necessary and important to have a good grasp of the electrical characteristics of SCG under short-circuit conditions. And it is desirable that, relations between characteristics and structureparameters of generators are explicitly and simply expre...
متن کاملOnline Aggregation of Coherent Generators Based on Electrical Parameters of Synchronous Generators
This paper proposes a novel approach for coherent generators online clustering in a large power system following a wide area disturbance. An interconnected power system may become unstable due to severe contingency when it is operated close to the stability boundaries. Hence, the bulk power system controlled islanding is the last resort to prevent catastrophic cascading outages and wide area bl...
متن کاملTransient Magnetic Field Analysis for the Localization of Electrical Faults in Superconducting Collared Coils
The follow-up of the construction of superconducting magnets for accelerators requires setting up of powerful diagnostic tools to detect weak electrical points in the superconducting coils at various stages of their fabrication. In particular some electrical short circuits well detectable after collaring of the magnet often disappear after the coil is uncollared for repair; therefore it is pref...
متن کاملOptimal Discrimination between Transient and Permanent Faults
An important practical problem in fault diagnosis is discriminating between permanent faults and transient faults. In many computer systems, the majority of errors are due to transient faults. Many heuristic methods have been used for discriminating between transient and permanent faults; however, we have found no previous work stating this decision problem in clear probabilistic terms. We pres...
متن کاملPerformance Analysis of Disk Type Variable Reluctance Resolver under Mechanical and Electrical Faults
Disk Type Variable Reluctance (DTVR) resolvers have distinguished performance under run out fault comparing to conventional sinusoidal rotor resolvers. However, their accuracy under inclined rotor fault along with different types of eccentricities includes static and dynamic eccentricities are questioned. Furthermore, due to thin copper wires that are used for signal and excitation coils of res...
