High voltage transmission line is the key equipment in power transmission, but the safety of power transfer is threatened by some indefinitely factors such as natural calamities (hoar frost, hurricane, etc.) and deliberate damage (stealing, destroy, etc.). For these reasons, the on-line monitoring device for the high voltage transmission line is very important to guarantee the operation of power grid...
IOT for PTDE is a typical cyber physical system (CPS), all power transmission and distribution equipment have been digitized and networked. It has the ability of efficient communication between not only equipment to equipment (E2E), but also equipment to human (E2H), which integrate information technologies into power grid by new operation and management model. In this paper, the architecture, function...
Permanent magnet synchronous generator (PMSG) is often linked to a PWM rectifier in order to provide a dc power supply. When such a system is used for variable speed applications, it is desirable to extend the operation speed range. Since the induced voltage of the PMSG increases with the speed, it is proposed in this paper to utilize flux weakening control to restrict the PMSG output voltage at high...
