It effectively solves the problem of large-scale pollution flashover on transmission lines in our country, whereas raises new problems. The existing experience shows that the RTV anti-pollution flashover coating will affect the steep wave performance of the disc suspension porcelain or glass insulators to a certain extent. At present, there is less research on the extent of the RTV coating impact to insulators, as well as the steep wave characteristics of factory compound insulators as new products. This paper studied different tonnage products of disc porcelain and glass insulators for UHV proj ect of State Grid Corp., conducted the air impact breakdown withstand voltage tests respectively in the Key Laboratory of State Grid Corp. At the same time, the samples were modeled and analyzed the field intensity distribution through ANSYS simulation software. The test results show that the steep shock amplitude decreases to 2.4 p.u. for products with a mechanical strength of not more than 210 kN, and the amplitude decreases to 2.2 p.u. for that of not less than 300 kN. For the factory composite disc suspension insulators, it is suggested that corresponding steep wave impulse voltage amplitude criteria should be given according to different mechanical strength levels of the products.","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":"114516270","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}

In this case, a comprehensive mining method based on FP-growth algorithm is proposed in this paper. Firstly, the data on meteorology, solar terms, holiday and total load in Pudong District of Shanghai for 546 days was clustered and generalized by K-means method. Then the original transaction sets was classified according to the counts of the clustering result. And they were mined by different methods comprehensively. Compared with association rules obtained by traditional algorithms, more association rules can be mined by the comprehensive mining method, with accuracy and robustness.

A hierarchical architecture that can effectively control large-scale ACs and a topology model of multi-agent related communication network were constructed. The demand side load reduction cost of the grid company was a quadratic function for the user's load reduction. A leader-follower decentralized coordination algorithm based on incremental cost of load response was proposed to meet the requirement of precise load control for a large number of dispersed ACs. Finally, case studies were given to show that the proposed method can achieve the optimal state of consistency under different load conditions and agent topology. In addition, an example was given to simulate the overall peak load regulation of large-scale ACs from top to bottom.","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":"116297374","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}

In order to study the development prospect of DC system, this paper discusses the reliability of DC distribution network. First, this paper introduces the characteristics of DC distribution system, and summarizes the main structures. Then, the reliability assessment model of power electronic equipment is established, and the reliability parameters of redundant components are calculated by using k/n(G) and Markov model. Moreover, the reliability index of DC distribution network is calculated based on the minimum cut set method. Finally, the IEEE RBTS Bus5 system is modified to calculate and compare the reliability indices of different distribution networks. The results show that the reliability of DC distribution network is limited by the reliability of equipment, and the reliability of DC system can be improved with the increasing proportion of DC load. In the future, with the improvement of power electronic equipment and the increase of DC load, the reliability of DC distribution network will be better than that of AC distribution network.","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":"125942362","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}
