After analyzing the fault characteristics of the sub-module failure of the MMC, a fault diagnosis method based on Wavelet Analysis-BP Neural Network is proposed. Wavelet Analysis is used to extract the fault feature information of, Neural Network is used for fault classification and fault degree determination. The MMC model is built on the PSCAD/EMTDC platform, and the three-phase voltage signals in the normal state and the fault state are collected. Then the wavelet transform is used to decompose the acquired signals to obtain the feature vector and normalize the feature vector. Finally, the feature vector is input into the neural network to diagnose the location and extent of the MMC fault. The simulation results show that the proposed method can accurately identify the open fault and fault extent of the MMC submodule.","PeriodicalId":257974,"journal":{"name":"2019 IEEE Innovative Smart Grid Technologies - Asia (ISGT Asia)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-05-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128676188","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}

Dissolved gas analysis (DGA) is often exercised as part of the maintenance process, and the Duval Triangle is a commonly applied method for classifying transformer faults. This paper proposes using the deep neural network to identify transformer fault type. Due to limited availability of field data, we simulate DGA data samples along with the fault type determined by Duval Triangle. Numerical results show that the deep neutral network provides very high accuracy in fault type identification and outperforms other learning methods such as k-nearest neighbor (k-NN) algorithm and random forest classifier method.","PeriodicalId":257974,"journal":{"name":"2019 IEEE Innovative Smart Grid Technologies - Asia (ISGT Asia)","volume":"36 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-05-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128950411","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}

When the worker enters the electric field during live maintenance, the distribution of electric field will change unevenly. When the electric field of human body reaches a certain intensity, it will bring personal injury to the worker. In order to avoid this situation, the finite element method is used to establish the transformer and human body model for numerical calculation of the working area. The distribution of electromagnetic field around the transformer and the change of electromagnetic field after joining the human body model are obtained. The safe distance is obtained by measuring the distance, so as to determine whether the corresponding protection needs to be taken. Protection measures.

Nevertheless, the intermittency and randomness of renewable energy resources pose significant challenges to the operation of microgrids, especially for MEMGs. To overcome the difficulties, we present a two-stage stochastic operation method to optimally schedule the units in MEMG under varied uncertainties from renewable energy resources, electricity price and loads. In the proposed method, the energy storage tanks and on/off statuses of generators are dispatched in advance; in the second stage, the output power of generation units and auxiliary units will be optimized to act as a supplement. We formulate the problem as a two-stage mixed-integer linear programming model and illustrate the benefits of the method by using a case study based on IEEE 33-bus distribution network.

However, connecting renewable energy sources to the power grid at a large scale will cause huge stability challenges at the connection interface. Virtual synchronous machine (VSM) technologies, which emulate the transient electromechanical characteristics of traditional synchronous machines, offer a unified interface for smart grid integration. With these technologies, all the renewable energy generators as well as the flexible loads could take part in regulating the grid frequency and voltage, thus improving the power grid’s stability. This paper presents the origin and development of VSM technology, and evaluates the mathematical model, control strategies and stability issues of the technology. It then summarizes VSM applications related to the grid interconnection of renewable energy, voltage sourced converter based HVDC (VSC-HVDC), motor speed regulation, and fast-charging interfaces. Finally, future research directions are assessed.","PeriodicalId":257974,"journal":{"name":"2019 IEEE Innovative Smart Grid Technologies - Asia (ISGT Asia)","volume":"24 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-05-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116914225","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}

To solve this problem, a pilot protection method based on current amplitude ratio on both sides is proposed. The method only needs to transmit the scalar signal which reduces the requirements on the communication system and synchronizing ability. It can operate correctly in the case of reclosing on permanent faults and weak output of the power plants. In addition, its principle is simple and reliable, and only requires a conventional sampling frequency and a computation speed. These features make it become a good choice for industrial application.
