A comparison of the Josephson array voltage standards of the Bureau International des Poids et Mesures (BIPM) and the Physikalisch-Technische Bundesanstalt (PTB), Braunschweig, Germany, was carried out in October 2014 at the level of 10 V. For this exercise, options A and B of the BIPM.EM-K10.b comparison protocol were applied. Option B required the BIPM to provide a reference voltage for measu...

Abstract Given the high proportion of wind power frequency/voltage stability problems, system based on synchronized coordinates (DFIG) mathematical model doubly-fed motor, studies a current source containing inertial link type turbine virtual synchronous control strategy, and loop design inner ring. Established in Matlab/Simulink simulation generator, generator realized inertia. Simulation resu...

In this paper, design and implementation issues of the real-time interactive multimedia distance learning system, which supports the W3C SMIL standard for presenting the real-time multimedia teaching material on the class over the Internet, are described. With content-sharing and interactive capabilities provided by this system and its tools, geographically dispersed students can devote themsel...

Voltage sensing technology is crucial in realizing distributed voltage at critical nodes of the power grid and providing key state variables to provide information support for control decisions. Among existing measurement methods, transformers have problems such as high insulation performance requirements limited installation locations. However, non-contact sensors designed based on electric fi...
