In conventional direct torque control (DTC), the stator flux is usually kept constant by controlling the x-axis component of the stator voltage in the stator flux reference frame. The torque is then controlled by the y-axis component of stator voltage. In this scenario, the stator current does not exceed its permissible value. However, in the so-called optimal efficiency mode, the induction mot...
We evaluate whether trends in the prevalence of disability among the aged can be investigated using the 1980 U.S. Census' public transportation question and the 1990 query on mobility limitation. Despite the obvious difference in the two questions, we found remarkable similarity in major cross-sectional patterns, such as those by age and sex, when comparing results from the two data sets. This ...
This article focuses the analysis on a static synchronous compensator (STATCOM) that operates simultaneously providing reactive power and several current harmonics of different frequencies (active filter or active impedance functionalities). Being more specific, this proposes general limitation method reduces references STATCOM whenever voltage limit converter is exceeded. In realistic operatio...
