Improvement of Stator Slot Structure based on Insulation Stresses Analysis in HV Generator
High voltage generators are being subject to higher voltage rating and are being designed to operate in harsh conditions. Stator windings are the main component of generators in which Electrical, magnetical and thermal stresses remain major failures for insulation degradation accelerated aging. A large number of generators failed due to stator winding problems, mainly insulation deterioration. ...
متن کاملStudy of Aging Characteristics of Generator Stator Insulation Based on Temperature Spectrum of Dielectric Dissipation Factor
In this paper, accelerated multi-factor aging tests in laboratory have been conducted on the stator ham of a large generator. During the period of aging, the temperature spectra of dielectric dissipation factor tan 6 of stator insulation were employed to investigate aging characteristics of insulation materials. Test results showed that the peak temperature T,,, of the tan 6 -T curve under 0.2U...
متن کاملDual Stator Induction Generator For Rural Electrification
The paper presents an electromechanical auto synchronized wind energy conversion system (WECS) for larger penetration of renewable energy sources (RES) in the rural electrification systems. The architecture of the WECS uses two stator windings at power frequency which provides harvesting of power to flow from WECS to load and to grid side when the generated power is in access. Asymmetrical six ...
متن کاملIgnition Coil Insulation Fault Detection Algorithm
Pulse singularities with variable amplitudes appear in the corresponding positions of ignition coil primary current waveform when insulation fault occurs during the ignition process. We propose an algorithm to detect the singularities in ignition coil primary current signal. First calculate the multiscale continuous wavelet transform of the fault signal. Then pursue modulus maxima from the coar...
متن کاملDouble Stator Induction Generator Model for Autonomous Operating Mode
Due to speed fluctuations of unregulated wind turbines, the terminal voltage may increase to dangerously high levels which have been reported to cause capacitor failure at wind farms. In this topic this paper examines a steady state performance analysis of stand-alone double stator induction generator self excited with two independents capacitors banks. An impedance approach based on double thr...
