It is significant to improve the handling level of grounding fault. Firstly, This paper analyzes the invalid data of the existing transient wave-recording fault indicator. A preprocessing method of recording data, based on the characteristics of temporal and spatial distribution of recording start, was proposed. Then the tripping adaptability index is proposed which includes the probability of fault expansion, the loss of outage and the risk of personal injury. The fuzzy comprehensive evaluation method is adopted to evaluate the tripping adaptability of the current fault. Finally, based on the importance of load, an adaptive trip protection strategy for single-phase grounding fault in non-solidly grounding network is proposed.","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":"121183588","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}

However, due to the distribution networks have multiple feeders and shorter lengths of each feeder, which are different from the transmission network, making it more difficult to locate faults. In this paper, based on the characteristics of the distribution network, an accurate fault location method of distribution network is developed using limited number of synchronization phase measurement units (PMUs). The method including two steps: First, based on the distribution parameter model, after the faults happen, the voltage and current information from the PMUs installed at the end of the line will be collected to calculate the voltage at the headend of the branching point, if the fault line exists fault branch, the headend voltage of the fault branch will be abnormal. Then, the fault distance could be calculated based on voltage distribution along the two ends of the fault branch. The effectiveness of the proposed algorithm is verified by electromagnetic transient simulation. The simulation result shows that the proposed algorithm only use limited number of PMUs to locate fault accurately without the need of PMUs on both ends of lines, which is not affected by transition resistance and fault type. Ensuring high accuracy, the proposed method is also very economic and has well application prospects.","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":"114557317","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}

Improving the local consumption rate of renewable energy in distribution network is getting more and more attention. The local consumption rate is related to the matching degree of the power output characteristics and the load characteristics. Energy storage system has bi-directional flow characteristics of energy, which provides more flexibility for the distribution network to absorb renewable energy locally. However, the cost of energy storage system is high at present, and the economic efficiency of blindly increasing energy storage capacity to improve local renewable energy consumption is poor. Therefore, reducing construction costs of energy storage system is the key to optimizing planning and configuration of energy storage capacity. In this paper, the energy balance of charge and discharge in a typical day is taken as constraints. A solution model of energy storage dynamic planning and configuration based on bi-objective with minimum capacity and charging and discharging power is established. Through an improved ant colony algorithm based on stratified sequencing method, the multi-objective optimal planning and configuration is realized by finding the optimal solution of energy storage power in the optimal target constraint of energy storage capacity. For planning and configuration of multi-objective energy storage system, the feasibility and effectiveness of the improved ant colony optimization algorithm are verified by an example.","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":"121693891","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}

Firstly, from the theoretical level, it is analyzed that the PV access will affect the node voltage, and the voltage control can be realized from both active and reactive power.

The equivalent sequence network diagram of the phase A-to-ground fault in the feeder of the resonant ground distribution system is used to construct the simplified circuit. And then the variation law of arc voltage and current waveform under the change of time constant $tau$ and dissipated power P is analyzed.
