Analysis of Transient Flow in the Case of Secondary Injection for Transient Vector Control (RESEARCH NOTE)
The purpose of this paper is to analyze the flow field structure in transient state and performance of secondary injection system for thrust vectoring in divergent section of a two-dimensional nozzle. Secondary injection for thrust vectoring in a two-dimensional nozzle is studied by solving three-dimensional Reynolds-averaged equations by means of fluent solver. Spalart-allmaras model was used ...
متن کاملtransformer differential protection using the fault-generated high-frequency transient components
Power transformers are the most important components of a power system, so their protection is a critical issue. This paper proposes a novel and efficient algorithm based on the high-frequency components of the differential current signal to discriminate between the magnetizing inrush currents and the internal faults. After detecting the over-current in the differential current signals, samples...
متن کاملTransient and Intermittent Fault Recovery without Rollback
Increasing chip density combined with heightened reliability expectations has spawned greater interest in fault tolerant design. In recent years, research into rollback and retry techniques has established them as an e ective approach to recovery from transient and intermittent faults. For applications with strict timing requirements, however, the high error latency inherent in retry approaches...
متن کاملTransformer Fault Detection Using Frequency Response Analysis
Power transformers prove to be a vital element or tool in electrical power supply and transmission system. They are capital intensive units and need to be monitored for faults. Faults in transformers leading to their failure are repugnant. Thus, there is a need to detect such faults at an initial level. This paper aims to detect, diagnose the nature and cause of mechanical faults, their identit...
متن کاملRecognition and Location of Power Transformer Turn to Turn Fault by Analysis of Winding Imposed Forces
Turn to turn fault is one of the major internal failures in the power transformers that if it is not quickly detected, can be extended and led to a complete transformer breakdown. So, the diagnosis and location of the turn to turn fault of the power transformer, as one of the most important equipment in the power system, is the main objective of this paper. For this purpose, a detailed model of...
