However, at present, the commonly used testing platform components are heavy and only suitable for testing before the terminal is installed, and lack portable devices that can be used in the field. The paper proposes a portable detector design. Based on the object model technology, a new three-tier architecture is designed. The detector adopts the design of built-in integral industry controller. Practicing in the field has proved that the device is easy to use and stable, and it can be widely used in scientific research, production and testing of the electric power industry.","PeriodicalId":329285,"journal":{"name":"2018 IEEE 2nd International Electrical and Energy Conference (CIEEC)","volume":"40 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127316419","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}

Many existing measuring methods are not suitable for the inter-harmonics measurement in the environment where plenty of power electronic devices exist. In this paper, a fast and precise measuring algorithm based on FFT and curve fitting is proposed to estimate the sub/super-synchronous harmonics. The windowing technique is used to reduce the spectral leakage firstly. Secondly, zero-padding is adopted to mitigate the picket-fence effect. Lastly, spectrum line curve fitting is applied to perform the inter-harmonic analysis. The simulation and experiment results indicate that the proposed algorithm is able to perform an accurate, real-time and anti-noise inter-harmonics estimation. Experiment results verify the accuracy and effectiveness of the proposed algorithm.","PeriodicalId":329285,"journal":{"name":"2018 IEEE 2nd International Electrical and Energy Conference (CIEEC)","volume":"32 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130679286","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}

Researching on the decomposition products is helpful for improving the personal safety and long-time reliability of SF6 insulated equipment. The decomposition characteristics of SF6 under corona discharge is not only related to the insulation fault type but also has close relationship with the concentration of H2O in the insulated equipment. The effects of H2O on the decomposition products and possible main reactions have been analyzed a lot, however, the influence mechanism remains unaddressed. This work is devoted to obtaining the effects of the concentration of H2O on the decomposition products and the main reaction pathways. In this paper, the chemical kinetic model is established for 50Hz ac point-plane corona discharge. The multi-step time is used to obtain the rapid discharge process in the plasma region and the slow reaction process in the gas region simultaneously. The concentrations of SOF2, SO2F2 and SO2 and the main pathways of these three species under different moisture content at 12h are obtained. The moisture content varies from 200ppm to 5000ppm with the oxygen content keeping at 100ppm.","PeriodicalId":329285,"journal":{"name":"2018 IEEE 2nd International Electrical and Energy Conference (CIEEC)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130742481","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}

At the same time, the wide application of synchronous phasor measurement unit(PMU) broadens the dynamic monitoring range of distribution network, providing a more reliable data source for loop closing control. Based on this, a loop closing control method based on PMU for active distribution network is proposed in this paper. Firstly, the method utilizes the high-accuracy operating data of PMU to judge the loop closing condition for active distribution network. The active loop closing control strategy of photovoltaic(PV) system have been put forward emphatically, in other words, the control strategy of PV system is actively converted to voltage/reactive power regulation control which could control the voltage for PV generation system at point of common coupling in real time during the loop closing control. Then, according to the voltage difference between two sides of loop closing buses, the network actively adjusts the situation that flexible load access to distribution network. The results of example validate that the loop closing control method for active distribution network proposed in this paper reduces the current from loop closing and current does not exceed the limit, confirming the effectiveness and accuracy of this method, reflecting the active control and management capabilities of the active distribution network.","PeriodicalId":329285,"journal":{"name":"2018 IEEE 2nd International Electrical and Energy Conference (CIEEC)","volume":"22 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130908824","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}
