Aiming at the shortcoming of traditional time domain sequence component detection algorithm, a kind of Fourier analysis algorithm of sliding-window mean-value in frequency domain was put forward. Symmetrical component method was used in calculating the sequence component of the fundamental phasor in this algorithm after using the calculation of continuous average sliding-window of Fourier analysis...
This paper proposes three dimensions of characteristics to describe the shock load, including reactive power, time, rate of change, then established the simulation model to did deep analysis on the impact of the voltage quality problem for shock loads connected into distribution network, it focuses on comparing the different dimension characteristic due to the difference of the impact of the voltage...
The equivalent circuit model is proposed in this paper, which is based on RC parallel networks, in order to model I–V performance and transient behavior of battery. The model consists of a series resistance, a self-discharge resistance and two RC networks. The I–V performance and transient behavior of the model are researched in time domain. Battery model efficiency is proved by frequency domain analysis...
This paper is to introduce the design and optimization the PoE Hub with redundancy based on the principle of EMC; through the simulation and analysis by FEM to the effectiveness of the hub of the electromagnetic shielding to enhance anti-interference performance of the hub according to the optimization to the problems discussed in the simulation. Having the aid of EMC simulation software, the analysis...
The imaging of bistatic SAR with asynchronous transceiver positions is studied in this paper. First of all, the geometry of the asynchronous transceiver model is constructed, and the approximation model of the echo from the bistatic SAR is obtained based on the analysis of the instantaneous transceiver distance. Asynchronous transceiver positions will lead to non-uniform SAR data. This paper first...
The verification for quality property of SDG fault diagnosis model is originally placed at the framework of symbolic model checking (SMC). SDG model is translated to the symbolic model verifier (SMV) module based on the finite state transition system definition firstly, and the quality property are formally analyzed and extended, then the verification approach are characterized and verified automatically...
To ensure the estimation accuracy of software project schedule and improve the timely completion of the projects, a quantitative estimation guide of software project was studied combined with some actual project cases. A non-linear regression curve was obtained by the use of statistical analysis methods, on base of this a schedule estimation guide model was built and the use of the model was studied...
