Authors: Liu Ya Duo , Zhang Jie
Published: September 2013

Euclidean distance measure is computationally simple and commonly used in the task of classification. However, it does not capitalize on any discriminant information from training samples, which is crucial to classification performance. In this paper, we learn a Discriminative Isotropic Space from both labeled and unlabeled data to improve classification accuracy as well as generalization ability. Our regularized objective function implicitly minimizes mutual information between input space and transformed space. There is no local optimum problem in our algorithm and its closed form solution can be easily obtained. Experiments on real data sets demonstrate the efficacy of our method.

Authors: Zhang Jian , Xiao Xiang Ning , Gao Ben Feng , Luo Chao
Published: September 2013

The methods for subsynchronous oscillation mitigation based on SVC and STATCOM are analyzed in this paper. According to the IEEE first benchmark model, the electrical damping coefficients respectively provided by SVC and STATCOM connected at the generator terminal, as well as positive damping condition, are deduced by complex torque coefficient approach. Correlative factors which influence the two positive dampings are compared. The analysis results indicate that the positive damping provided by SVC is proportional to the size of system voltage. The positive damping provided by STATCOM is not affected by the size of system voltage, which is mostly proportional to the subsynchronous voltage produced itself. The controllers of SVC and STATCOM are designed and the positive dampings separately offered by SVC and STATCOM are optimized by phase compensation with test signal method. The time domain simulation reveals that STATCOM has stronger damping ability than SVC in the case of short circuit fault.

Published: September 2013

In recent years, Internet traffic classification using machine learning has become new direction in network measurement. In this method, choose the appropriate traffic features is the key. The selection of feature in previous studies dependent on the specific data set and does not have the versatility to identify the data sets captured in the actual network conditions. We analyze and select a group of features based on public data set and the data collected in the actual network. Experimental results show that the selected feature set with stable performance and effective identification ability by using C4.5 decision tree method.

Published: September 2013

This paper discusses the establishing method of DC voltage of modular multilevel converter (MMC). Firstly the structure of MMC and the charging principle of sub-modules (SMs) are introduced in order to control the DC voltage of MMC and reduce the switching loss. It is pointed out that the DC voltage control in MMC includes two parts, the DC voltage establishment of system and the voltages control of SMs. For the DC voltage control in system, the control theory is analyzed, and the corresponding control strategy is proposed. Meanwhile an improved voltage balance control strategy for SM is proposed by the improvements of the traditional voltage sorting method to reduce the high switching frequency caused by the blind action of switching devices in the SM control. Finally, the simulation results based on PSCAD/EMTDC show that DC voltage in MMC can run in the rated value steadily, and the switching frequency is reduced significantly.
