Advancements in Partial Discharge Analysis to Diagnose Stator Winding Problems
On-line partial discharge (PD) testing has been used for over 50 years to assess the condition of motor and generator stator winding insulation systems. In the past decade, advanced hardware and software have enabled superior methods of converting the PD data into practical information about the relative condition of the insulation, as well as determining the root causes of any insulation deter...
متن کاملA novel protection scheme for synchronous generator stator windings based on SVM
This paper proposes a novel scheme for detecting and classifying faults in stator windings of a synchronous generator (SG). The proposed scheme employs a new method for fault detection and classification based on Support Vector Machine (SVM). Two SVM classifiers are proposed. SVM1 is used to identify the fault occurrence in the system and SVM2 is used to determine whether the fault, if any, is ...
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 کاملPartial Discharge Analysis for Insulation Systems of Electric Rotating Machines with Various Voltage Stress
High voltage insulation is loosing its quality during the operation of high voltage machines and generators. Degrading high voltage stator insulation is the main reason for sudden breakdown of stator windings. Partial discharge measurements can reveal a lot of defects in stator windings of high voltage rotating machines with operating voltage more than 3,3kV. Partial discharge monitoring provid...
متن کاملInvestigation of Partial Discharge Propagation and Location in Multiple-α and Single- Α Transformer Windings Using Optimized Wavelet Analysis
Partial discharges (PD) are recognized as the main cause of the inner insulation deterioration process in power transformers. Therefore, the optimum inner insulation design is one of the challenges a transformer designer is faced with. Transformer strength, especially during transient conditions, is a criterion for transformer insulation designers. This challenge has made designers initiate and...
