The mechanical damper is the critical element which strongly determines the travel curve behavior of the CB when opening. Most dampers used in MV-CB contain oil as one of the damping elements. The viscosity of the oil is varying with temperature. Therefore also the damping characteristic of oil damper is temperature depending. To make sure the CB works correctly under all ambient conditions encountered in service measures have to be taken to make sure the CB is able to operate correctly and reliably and fulfills the switching duties required. An existing MV-CB was tested under different ambient temperatures and showed unsatisfactory results. The design of the CB was analyzed and the damper identified as the main root cause. A special test setup for the complete CB and a test jig for the damper only was developed. Based on the findings obtained with this new setups the damper was optimized only by modifying some internal parts of the damper, keeping the outside dimensions and the oil filling the same. Thus eliminating the need of any changes on the CB design. The tests on the CB with the optimized damper showed excellent results at all requested ambient temperature levels. The newly developed damper test rig can be used to quickly and efficiently derive damper parameters or for performance testing of dampers during development or final testing in damper production.","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":"127141922","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 improve asset management performance evaluation system of distribution network (DN) in China, a new performance evaluation model of asset life cycle management(LCM) is proposed. Firstly, through an in-depth analysis of development characteristics of DN and the various demands of users in China, based on interface between users and DN, a comprehensive performance evaluation system is constructed for asset LCM covering economy, service efficiency and social benefits and other aspects. According to the purpose of enterprise and the characteristics of each index, an optimal combination weighting method, which takes both subjective and objective factors into consideration, is used to weight the service efficiency and social benefit indexes. Based on this, the performance evaluation model and calculation method of DN asset management are established. Finally, the evaluation method is applied to the performance evaluation of annual assets management of the DN in 14 counties of a municipal power company.","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":"124845089","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}

If photovoltaic power continues to operate at the maximum power point and not provide support for the frequency regulation of the system, it will probably affect the frequency security of the power grid. At present, some related studies have taken photovoltaic power generation at the maximum power point as the premise. When the frequency of the power grid rises, photovoltaic power generation reduces power output according to the set slope to participate in power grid frequency regulation. It can play a role in the frequency support of the power grid, but it is still not enough. In this paper, a new control strategy of photovoltaic power generation to participate in the regulation of the power grid frequency is proposed. There is a certain reserve for the photovoltaic power generation through power curtailment, so that the photovoltaic power has the ability to participate in the frequency regulation of the power grid by increasing or reducing the power output. When the power grid is disturbed, different active power regulation modes are used to participate in the frequency regulation of the power grid according to the initial change rate of the power grid frequency. Finally, a simulation example is given to verify the effectiveness of the proposed strategy.","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":"126044971","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}
