Abstract—this paper expounds a simulation model of a self-excited asynchronous generator (SEASG) feeding RL load in conjunction with an AC/DC/AC converter fed RLC series circuit connected at the point of common coupling (PCC).Simulation model of the proposed system have been developed by using Mat lab/Simulink. The result shows that the effect of RLC series circuit when operated at variable fre...

Abs t r ac t . We give an overview of the parallelization work done in PAROS. The specific parallelization objective has been to improve the speed of airline crew scheduling, on a network of workstations. The work is based on the Carmen System, which is used by most European airlines for this task. We give a brief background to the problem. The two most time critical parts of this system are th...

Renewable energy is derived from natural processes that are replenished constantly. Included in the definition is electricity and heat generated from solar, wind, ocean, hydropower, biomass, geothermal resources, and bio-fuels and hydrogen derived from renewable resources. Each of these sources has unique characteristics which influence how and where they are used. This paper presents the model...

ABSTRACT In this paper, we present a temperature compensation method for logarithmic CMOS image sensors. As Bandgap technique, the compensation circuit generates VPTAT1 and VPTAT2 voltages to compensate temperature variation of the sensor output signal voltage (Out-AC-Signal) which we call VCTAT1 and output reference voltage (VRef−ph) which we call VCTAT2. The proposed method is divided into th...

This paper presents a DSP-based high performance digital automatic voltage regulator (D-AVR) for use on engine generator. The H∞ control approach is applied to the engine generator excitation control system (ECS) for the purpose of tracking a r.m.s. of sinusoidal ac voltage to a specified value. Since the implementation of the control laws has tended to the digital microprocessor, the paper ext...

This project proposes a novel three phase nine switch AC/AC converter topology. This converter features sinusoidal inputs and outputs, unity power factor, and more importantly, low manufacturing cost. The Operating principle of the Converter is elaborated, its modulation schemes are also discussed, and experimental results from a 5kVA prototype system are provided.

Railway traction is a more stochastic heavy load connected system. Due to the usage of ac-dc converters and ac-ac converters, the various power quality issues become the major problems in the electric system. This paper presents a review on power quality conditioners suitable for Railway traction based on the configuration, components involved and on the technical and economic considerations. M...

Conversion of existing high voltage long AC transmission line into combined AC-DC system can bring the benefit stability improvement. Of late, most developments in analysis are simulation based. Sometimes it is difficult to draw a generalized conclusion through result. In this case, an analytical model be perfect tool analyze fault and get concrete decision about future planning. This paper pre...

The modern data compression is mainly based on two approaches to entropy coding: Huffman (HC) and arithmetic/range coding (AC). The former is much faster, but approximates probabilities with powers of 2, usually leading to relatively low compression rates. The latter uses nearly exact probabilities easily approaching theoretical compression rate limit (Shannon entropy), but at cost of much larg...

In this paper the two novel recurrent wavelet neural network (RWNN) controllers are proposed for controlling output direct current (DC) voltage of the rectifier and output alternate current (AC) voltage of the inverter. The output power of the rectifier and the inverter is provided by three-phase permanent magnet synchronous generator (PMSG) system directly-driven by permanent magnet synchronou...
