In order to study the surface discharge characteristics of C4F7N gas mixture under the needle-plane electrodes, a fluid model of surface discharge was established using COMSOL Multiphysics for simulation, and the change patterns of electric field and photon flux during the development of streamer were obtained. By obtaining the change law of photon flux, it can provide the theoretical discharge. The simulation results show that the development process of streamer can be divided into three phases: streamer generation phase, streamer deceleration phase and streamer acceleration phase. During the whole process, the change trend of photon flux is basically consistent with the change trend of electric field. In the acceleration phase, the streamer gradually moves away from the needle electrode, the background electric field gradually decreases, and the frequency generated by the electron collision reaction weakens, leading to the slow development of the streamer, and the electric field and the photon flux at streamer head gradually decrease. In the acceleration phase, the streamer is converted from parallel to the plane electrode to perpendicular to the plane electrode, and the potential gradient becomes larger, leading to a faster development of the streamer and a gradual increase of the electric field and photon flux at streamer head.","PeriodicalId":118112,"journal":{"name":"2022 7th Asia Conference on Power and Electrical Engineering (ACPEE)","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2022-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114581071","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}

It is urgent to study the integration planning scheme of 5G network and smart distribution network to achieve benign two-way interaction between the two networks. This paper analyzes the integration of two networks from two aspects: 5G network improves the operation performance of smart distribution network and smart distribution network contributes to the promotion and construction of 5G network. On this basis, the key elements of the integration of 5G network and smart distribution network are sorted out, including energy elements, information elements and resource elements, and the integration planning of smart distribution network integrating 5G network is proposed. It is realized from three perspectives: site layout planning based on power and energy balance, cooperative planning of two networks and joint construction and sharing planning of 5G network infrastructure and smart distribution network facilities.","PeriodicalId":118112,"journal":{"name":"2022 7th Asia Conference on Power and Electrical Engineering (ACPEE)","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2022-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116724366","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 the system, the digital drawing force sensor is used to measure the force status of external stay wire, support rope or internal stay wire of internal suspended gin pole tower erection in real time, as well as inclination sensor, and then the measurement value is transmitted to the mobile phone or PC terminal in real time, in which, the safe force range is set. When the measured drawing force is close to 80% of the safe force or other critical conditions, the alarm signal will be sent and the construction work must be stopped immediately.

In this paper, a feature extraction and identification method are proposed by experimentally simulating the partial discharges of typical defects inside the distribution network equipment. Firstly, different discharge models are built and the UHF sensor is used to obtain the partial discharge signals, and then the partial discharge statistical characteristics are calculated by analyzing features of the 2D and 3D partial discharge patterns. Based on various supervised machine learning algorithms, 3 typical defects are identified by the statistical characteristics using the classification learner. The results show that the selected statistical characteristics: the maximum amplitude of discharge, the average amplitude of discharge and the ratio of positive and negative half-period total discharge amplitude can well reflect the discharge characteristics of different defects and can distinguish between different types of discharges. At the same time, the identification accuracy of the three discharge types is high, which can achieve an accurate diagnosis of the fault types.","PeriodicalId":118112,"journal":{"name":"2022 7th Asia Conference on Power and Electrical Engineering (ACPEE)","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2022-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125060483","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}
