This paper presents a wind-driven DC power generation and control system modified by a doubly fed induction generator (DFIG), which stator is connected with a full-power diode rectifier to supply DC power to a stand-alone load and rotor is connected to the DC link with a PWM converter in charge of regulation of frequency and voltage on stator side. The transient character and behavior of current,...
The relationship between emitted energy spectrum and multipactor threshold of impedance transformer is investigated numerically in this paper. Secondary electron yield remains the same, while the emitted energy spectrum changes. Numerical simulations are provided for different cases of emitted energy spectrum. We analyze the practicability of this method in theory and simulation. Simulation results...
This paper analyses the connection availability of a protection paradigm, termed permanent dedicated path protection (P-DPP), in WDM mesh networks. An analytical model for calculating the unavailability of P-DPP is introduced. Numerical results on COST239 European network show that the average unavailability of the network is proportional to blocking probability of the network, and fits well with...
Physical Cell Identity (PCI) is cell identifier on the physical layer which can be used to create synchronization signals. There is a mapping between synchronization signals and physical cell identity, and then User Equipment (UE) can search cells through this mapping. Traditionally, PCI was configured during network planning process. While with 3G Long Term Evolution (LTE) has been prevalent in the...
