When considering grid integration, it is recognized that wind farms are able to bring about power quality impacts at the connection point. Focusing the attention towards this framework, a large amount of effort has been given to achieve the required level of compatibility between the wind turbine and the AC grid. Amongst the various existing power quality phenomena, harmonic distortion emerges as...
Transformers are generally energized by closing the circuit breakers at random times. Consequently, this operation generates high transient inrush currents as a result of the asymmetrical magnetic flux produced in the windings. In light of these facts, this paper presents a strategy to control the switching phenomena which occurs during power transformer inrush. The general idea consists of calculating...
This paper is aimed at proposing and validating a time domain model for window-type air conditioner apparatus and corresponding insertion in the ATPDraw platform. The suggested computational model performance exactness is evaluated through comparison of simulation and experimental results with ideal and non-ideal supply voltage conditions. Once the representation effectiveness is proven, the model...
This paper describes a different approach which has been used to easily visualize the harmonic current components generated by multi-converter systems such as those arrangements used in large electrochemical industries. These configurations are normally established by using a large number of 6-pulse converters fed by transformers with suitable phase shifts. The developed method is based on a steady-state...
