This paper provides a solution: using the gravity heat pipe heat transfer technology to extract the heat energy in the high temperature area, and according to the thermoelectric power generation technology to convert heat energy into electrical energy to transport to electrical equipment, to achieve the purpose of energy recovery and utilization. In this paper, the ANSYS Workbench software is used to model and analyze the thermoelectric generator, and it is found that the temperature difference is an important factor affecting the overall output power of the device. In order to improve the output power of the device, the experimental platform was built to simulate the spontaneous combustion heating process of coal gangue, and the optimization was carried out from three aspects: the arrangement interval of heat pipe, the setting of cooling water flow and the number of thermoelectric generators in series. The experimental results show that when a heat pipe is arranged at intervals of15 cm and the cooling water flow is set to 2.1 kg/min, the temperature difference between the two ends of the thermoelectric generator can be maintained to the maximum. After optimization, when the temperature difference between the cold and hot ends of the thermoelectric generator is maintained at 200°C, the maximum output power of the thermoelectric generator can reach 35 W. It can be verified that the device has practical value and broad development space.","PeriodicalId":304779,"journal":{"name":"2022 9th International Forum on Electrical Engineering and Automation (IFEEA)","volume":"369 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-11-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116539187","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}

Therefore, transmission line inspection combined with artificial intelligence has gradually come into people’s vision. At present, there are some explorations in the performance, stability, robustness and use value of the model. However, the exploration of the security performance of the model in the current relevant literature often occurs in the defense and structure of different samples, and the robustness evaluation content is not reasonably standardized. Aiming at the power inspection scenario of power grid application, this paper integrates the artificial intelligence model evaluation indicators in academia and the model evaluation system in the specific scenario of industry, designs customized evaluation indicators in combination with the power scenario, focuses on the robustness indicators of power grid power inspection, and studies the countermeasure sample generation technology of power image. The generated countermeasure samples will effectively simulate the attacker’s intention, and propose effective countermeasure algorithm measurement indicators; For the evaluation of the robustness against various hacker and organizational attacks, an artificial intelligence model robustness evaluation system is formed, which can effectively support the high-quality development of big data artificial intelligence platform and promote the safe, effective, reliable and stable operation of artificial intelligence models in power scenarios.","PeriodicalId":304779,"journal":{"name":"2022 9th International Forum on Electrical Engineering and Automation (IFEEA)","volume":"49 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-11-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124777831","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}
