Terminating alternator
In this paper, we present an program that enables the transformation of a nonterminating alternator into a terminating alternator. Our solution is stabilization preserving and has the potential to preserve maximal concurrency (if available) provided by the non-terminating alternator. It can also be used to transform a program that is stabilizing in interleaving semantics into a program that is ...
متن کاملSwitched Reluctance Machine For A Starter-Alternator Micro- Hybrid Car
Living in a world where environment protection and energy conservation are the first worries, the development of hybrid vehicle seems to be an accelerated pace. There for, recent efforts are directed toward developing an improved propulsion system. One of the most valuable solutions is the starter alternators [19]. This paper presents an advanced development of a switched reluctance starter-alt...
متن کاملA New High Frequency Grid Impedance Estimation Technique for the Frequency Range of 2 to150 kHz
Grid impedance estimation is used in many power system applications such as grid connected renewable energy systems and power quality analysis of smart grids. The grid impedance estimation techniques based on signal injection uses Ohm’s law for the estimation. In these methods, one or several signal(s) is (are) injected to Point of Common Coupling (PCC). Then the current through and voltage of ...
متن کاملDesign and Development of a Two-megawatt, High Speed Permanent Magnet Alternator for Shipboard Application
Conventional gas turbine generator sets consist of a high speed turbine coupled to a low speed alternator through a speed reduction gearbox. This is required to maintain the alternator output frequency at 50 Hz or 60Hz, as output frequency is directly proportional to speed. Since power is also directly proportional to speed, the conventional system is bulky and possesses a very large footprint....
متن کاملStudy of Shaft Voltage on Short Circuit Alternator with Static Frequency Converter
Electric machines are driven nowadays by static system popularly known as soft starter. This paper describes a thyristor based static frequency converter (SFC) to run a large synchronous machine installed at a short circuit test laboratory. Normally a synchronous machine requires prime mover or some other driving mechanism to run. This machine doesn’t need a prime mover as it operates in dual m...
