Secondly, big data analysis technologies such as data mining, machine learning and data visualization are applied to solve problems in distribution network production. For example, accurate location of the fault can be found with help of multisource information from different devices and systems. And we can also be aware of the risk points in distribution network through history data analysis. Finally, this Paper explains how to promote lean management of distribution network in the fields of asset, operation, maintenance and investment based on the big data platform and big data analysis methods. In addition, the feedback procedure sets up a bridge between application and data collecting, which further improve the data quality. Those management measure have been piloted in several cities in Jiangsu. The result proves that they can improve power supply reliability and reduce operating costs significantly. Two practical cases are given to show how they work.","PeriodicalId":142885,"journal":{"name":"2018 China International Conference on Electricity Distribution (CICED)","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2018-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130389481","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}

The role of arc suppression coil grounding mode is when the grid single-phase ground fault occurs, arc suppression coil will provide inductor current to compensate the capacitor current. It is conducive to prevent the arc-reignition, to achieve the purpose of arc extinguishing, which will reduce the high amplitude over-voltage probability, to preventing further expansion of the accident. Engineering is generally used the overcompensation method for the wayto prevent the occurrence of resonance phenomenon. But, the capacitive current data used in the overcompensation method of the engineering are generally designed to be estimated based on recent or long-term loads and current equipment conditions. In the following years of substation operation, due to the rapid increase in load, the rapid expansion of the transmission line, the actual capacitor current is often quite different with the originally estimated one. Especially for large-scale urban distribution network with large number of cable or large-scale overhead lines to transform the cable, the design of the over-compensation mode of operation may no longer be established, become fully compensated or even under-compensation. Several obvious voltage waveform distortion of the actual distribution network is analyzed in this paper. The resonant energy spectrum of each phase is analyzed by MATLAB, and it is pointed out that the resonance of the voltage waveform is caused by the resonance of the zero sequence circuit. And use RTDS simulation system to modeling and analysis this situation. The simulation results are in good agreement with the actual waveforms, which will verified that the results of this paper are correct.","PeriodicalId":142885,"journal":{"name":"2018 China International Conference on Electricity Distribution (CICED)","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2018-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129240480","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}

By analyzing the output characteristics and typical 24h load characteristics of wind power, the characteristic index system of wind power peak shaving load has been established. And the impacts of different indicators on wind power peak shaving have been analyzed. Through the calculation and analysis, the accurate value of wind power peak shaving regulation probability and wind power peak shaving rate could be obtained. In the study of optimal allocation of existing pumped storage power stations, most of the wind power peak shaving rates are considered according to a fixed value. But it failed to analyze the rationality of the fixed value in depth. This paper provides an in-depth analysis of the simplified calculation of wind power peak shaving rate, and through the comparative analysis of the maximum planning capacity of wind power, some useful conclusions are obtained.","PeriodicalId":142885,"journal":{"name":"2018 China International Conference on Electricity Distribution (CICED)","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2018-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121172152","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}
