Department of Physics of Molecular Imaging Systems, Institute for Experimental Molecular Imaging, RWTH Aachen University, Aachen, Germany 2012, our group presented the Hyperion IID platform which uses PDPC’s digitial SiPMs (DPC). In this work we use the same platform equipped with scintillator dimensions closer to a clinical application. This allows an investigation of the time of flight (ToF) ...

Battery electric vehicles demand a wide variety of charging networks, such as stations and wallboxes, to be set up in the future. The high power (typically range couple kW hundred kW) possibly long duration process (up more than 24 h) put some special requirements on electrical infrastructure stations, sockets, plugs. This paper gives an overview technical design considerations for vehicle plug...

The CVT equipment running on site is slightly modified to form a hybrid achieve transient overvoltage measurement, which theoretically feasible and practical. In order study the voltage division method based measure of power system, that is, low capacitor C3 connected in series between terminal medium C2 traditional ground, measurement realized through C3. This article uses ATP-EMTP establish i...

Aiming at the problems emerging in a pulse width modulation (PWM) drive system with long cables, accurate modeling of power cables is premise for predicting and analyzing these relevant phenomena, proper filter design key solution to problems. This paper proposes high-frequency cable models represent frequency-dependent characteristics, especially resistance which an easily overlooked factor th...

Abstract For the overvoltage problem brought by access of high-penetration photovoltaic power plants to low-voltage distribution network, this paper chooses deal with it using reactive regulation capability plant inverters, which reduces equipment investment in line voltage regulation. Based on theory inverter, a finite set model predictive direct control method is proposed constructing virtual...

Overvoltage is becoming increasingly prevalent in distribution networks with high penetration of renewable distributed energy sources (DERs). Local control converter-based resources a flexible and scalable method to prevent this growing issue. Reactive power used for voltage many local schemes. However, the typical range R/X ratios lines indicates that mitigation overvoltage often requires exce...

Abstract Electroconductive composites are modern materials that commonly used in many industries such as construction industry and machine-building industry. For example, these can be useful sensors for monitoring changes constructions, shielding stray currents from electrification networks, electromagnetic radiation operating rooms, cathodic protection against moisture or overvoltage of buildi...

The roof arrester of electric multiple units (EMU) can efficiently limit the overvoltage, and ensure safe operation EMU electrical equipment. In process high-speed operation, traction power supply system is often affected by overvoltage. addition, explosion accidents occasionally occur. this paper, on-line voltage measurement developed. By analysing a large number waveforms, abnormal divided in...
