In the DC breaking scenario, the action time of the electromagnetic repulsion mechanism is required to break to the full opening distance within 2ms as much as possible, while ensuring a long service life. In this paper, the basic principle of electromagnetic repulsion mechanism is analyzed firstly, and then the simulation model of \"coil-repulsion disc\" type electromagnetic repulsion mechanism is built by using finite element software to analyze six important parameters (number of turns of coil, coil height, coil width, repulsion disc height, energy storage capacitance capacity and charging voltage). Finally, the parameters of the electromagnetic repulsion mechanism are optimized based on NSGA-II algorithm with the displacement and coil current of 2ms as the optimization target. The simulation results show that when the coil is 36 turns, the coil height is 7.75 mm, the coil width is 1.8 mm, the repulsion disc height is 8.35 mm, the storage capacitor capacity is 8000μF, and the charging voltage is 1100 V, the 2ms motion displacement of the electromagnetic repulsion mechanism increases from 11.68 mm to 12.56 mm compared with the initial design, and the coil current decreases from 6830A to 5580A, which can improve the opening speed and extend the life.","PeriodicalId":231392,"journal":{"name":"2023 IEEE International Conference on Power Science and Technology (ICPST)","volume":"104 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-05-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131963348","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, the complex and changeable environment often causes the temperature difference array to operate under the condition of non-uniform temperature difference (NTD), the output power is low, and the power-voltage (power-voltage, P-V) curve has obvious multi-peak characteristics, which is not conducive to the system stable and efficient operation. Traditional strategies are difficult to completely suppress and eliminate this adverse effect, so a modular temperature difference array reconstruction technology based on artificial bee colony (ABC) is proposed, which aims to fundamentally solve the problem of various uneven temperature distributions to TEG system. Firstly, a (15×15) modular TEG array reconstruction model is built by MATLAB/Simulink, the entire TEG array is divided into three array modules, and various dynamic reconstructions can be completed only by configuring two switch matrices, reducing the construction and operation costs of TEG system. Then, ABC is guided to perform reconstruction optimization with the goal of maximizing output power. The simulation results show that ABC can effectively smooth the P-V curve, increase the output power, reduce the voltage unbalance, fully tap the power generation potential of TEG array, and ensure the safe and stable operation of the system.","PeriodicalId":231392,"journal":{"name":"2023 IEEE International Conference on Power Science and Technology (ICPST)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-05-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131081295","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}

A large number of devices represented by voltage source converter (VSC) have been incorporated into the power grid, which has caused a series of stability problems correspondingly. Thus, this paper starts from the distribution feeder parameters and investigates their influence on the stability of the multi-VSC system. In this paper, an improved Kron reduction method is proposed to reduce the order of multi-VSC system equivalently. This method can eliminate unnecessary nodes in any power network which contributes to simplifying later calculation. Then based on the reduced multi-VSC system, the dynamic equation of VSC is established and extended to multi-VSC system. Third, a new system stability criterion is proposed by using the average method. In order to analyze the influence of distribution feeder parameters on multi-VSC system stability, the generalized short circuit ratio calculation formula of the multi-VSC system is introduced. For the real system, the influence of the distribution feeder parameters on the stability of the system can be obtained by finding out the relationship between the new stability criterion proposed in this paper and the generalized short-circuit ratio. The case study has illustrated the effectiveness of the proposed methods. The conclusion of this paper is helpful to study the influence of complex distribution feeder on multi-VSC system stability and provide the basis for stability analysis of specific real power network.","PeriodicalId":231392,"journal":{"name":"2023 IEEE International Conference on Power Science and Technology (ICPST)","volume":"59 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-05-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130720874","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, because dry-type transformers are subject to high internal electric field stress, mechanical stress and thermal stress, local overheating is more likely to occur, thereby accelerating the deterioration of insulation materials, so the temperature distribution study of dry-type transformers is increasingly important. Combined with the actual temperature rise test, studying the temperature distribution of dry-type transformers under natural convection is the key point of this simulation. Based on previous research, considering the dynamic change process of actual temperature rise, this paper obtains a new idea of temperature distribution of transformers, that is, using transient analysis of natural convective heat transfer in dry-type transformers. Firstly, the transformer model and all the conditions for the required solution (boundary, excitation, mesh) are given; Then, the distribution of the transformer heat-current field within 10h was analyzed by transient analysis, and the hot spot temperature of the dry-type transformer was obtained. Then, the axial temperature distribution of transformer windings and cores was analyzed, and the temperature distribution inside and outside of the windings was compared and analyzed, indicating the temperature distribution situation. Finally, a fixed point, that is, the endpoint on the high-voltage winding, is selected for fitting and analysis of its temperature distribution. Finally, the method proposed in this paper effectively solves the temperature distribution and transient change process of dry-type transformer, and makes innovative contributions to the research in this direction.","PeriodicalId":231392,"journal":{"name":"2023 IEEE International Conference on Power Science and Technology (ICPST)","volume":"6 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-05-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124403749","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}
