Firstly, the Hankel matrix is constructed by the PD sample sequence and singular value decomposition (SVD) is performed on it. Then the singular values corresponding to the narrowband interference are adaptively extracted by the K-means algorithm. Finally, the narrowband interference is reconstructed and removed from the original sample sequence to obtain the PD pulses. The de-noised results of the simulated and measured signals show that: Compared with the FFT threshold method and the wavelet de-noising method, the proposed method has better suppression effect on the narrowband interference; The de-noised PD waveform of the proposed method is more similar to the original PD pulses, which is more conducive to the subsequent analysis of the PD pulses.","PeriodicalId":387293,"journal":{"name":"2019 4th International Conference on Power and Renewable Energy (ICPRE)","volume":"119 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123580152","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Machine learning can ensure both accuracy and rapidity of renewable energy cascading tripping identification. A method of cascading tripping evaluation based on support vector machine considering conservative principle is proposed. The method combines causal analysis and statistical theory to extract key characteristic quantities. The mapping relationship between system characteristic quantities and renewable energy tripping is established by training to identify cascading renewable energy tripping under contingency and update the prediction model rolling with simulation results to avoid the occurrence of misjudgment.

CLLC resonant converters have the advantage of high efficiency, often acting as a DC/DC converter for the OBC. In this work, the forward and reverse output power capability of the CLLC topology is analyzed. It is found that the forward and reverse output power capability of the CLLC converter is asymmetric, which makes it difficult to fully meet the application requirements in OBCs. Therefore, this paper proposes a CLLC resonant converter with a modified half-bridge and full-bridge structure that can achieve forward 6.6-kW and reverse 3.3-kW power conversion.

Meanwhile, whether it will cause DC current impulse, whether DC current over zero is caused, whether system of energy can be transferred quickly, whether can the fault area could be isolated quickly and when faults occur in the polar regions, which strategy will lead to another pole commutation failure are considered. When faults occur in the valve area, whether a strategy selected will lead to another valve group occur commutation failure, thus get more reasonable strategies of region fault and valve fault blocking.

The framework of TensorFlow was used to construct a model for feature extraction and result prediction. Some power consumption units in a prefecture-level city were selected for analysis.
