An energy degrader driven by a stepper motor is used to regulate the proton beam energy to the range of 70-240 MeV for clinical requirements. However, the interactions between protons and materials in the energy degrader lead to severe ionizing radiation, which will damage the stepper motor nearby, consequently deteriorating the beam quality. Shielding made of composite materials must be used to block the gamma rays and neutron effectively. For a given shield design, the stepper motor’s maximum radiation exposure does not always correspond to the severest beam loss. FLUKA simulation results show that the stepper motor will suffer the maximum radiation dose rate of 5.62 Gy/h at 190 MeV of output beam energy. A composite shielding material of Pb and polyethylene is chosen to shield ionizing radiation. Because of the installation space restriction, the total shielding thickness is 14 cm. When the Pb thickness is 5.5 cm and the polyethylene thickness is 8.5 cm, the motor’s suffered dose rate achieves the minimum, which is only 1/4 times the case without shielding.","PeriodicalId":308213,"journal":{"name":"2021 4th International Conference on Energy, Electrical and Power Engineering (CEEPE)","volume":"35 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-04-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114456797","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}

The great variability in Insulated Gate Bipolar Translator (IGBT) failure times caused by the very different operating conditions experienced and the stochasticity of their degradation processes suggests the adoption of condition-based maintenance approaches. Thus, the development of research for the aging process of IGBT is of key importance. In this paper, we investigate the results of performing accelerated aging experiments (Gate-oxide layer aging). Our objective is to discuss and analyze the curve of the IGBT gate-oxide layer aging process under long working hours. During the experiments, the switching characteristic parameters were measured in the different aging processes. According to the mechanism study, it can be found that the turn-off delay time and the turn-on delay time are related to Miller capacitance, and Miller capacitance is related to the degree of aging. In this paper, relevant aging parameters are screened for aging trend analysis. The results show that the gate oxide layer aging process of IGBT is gradual, and the aging process model of IGBT was finally established.","PeriodicalId":308213,"journal":{"name":"2021 4th International Conference on Energy, Electrical and Power Engineering (CEEPE)","volume":"30 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-04-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114804200","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 of great significance to use reasonable methods to predict photovoltaics. Based on this, this paper proposes an adaptive ultra-short-term rolling prediction method to improve the accuracy of the prediction model according to historical photovoltaic power. First, wavelet decomposition is used to extract photovoltaic energy, which divides the photovoltaic power curves into stable and fluctuating types. Then, prediction models are established according to the types of photovoltaic power curves respectively. Finally, a dynamic time warping (DTW) algorithm is used to measure similarity between the predicted photovoltaic power and the historical photovoltaic power during every rolling forecast, and an appropriate model is selected to predict the photovoltaic power at the next moment. This article will take the photovoltaic data of a 2.8MW photovoltaic power plant in a city in China as an example to verify the feasibility of the proposed model.","PeriodicalId":308213,"journal":{"name":"2021 4th International Conference on Energy, Electrical and Power Engineering (CEEPE)","volume":"3 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-04-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134432719","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}

Two key technologies are given for multi-dimensional aggregation model construction and ubiquitous coordination and optimization of source-networkload-storage interaction. The developed ubiquitous dispatching control system with multiple coordinated source, grid, load and storage was put into operation in the East China Electric Power Control Sub-center of State Grid. The construction cost is relatively small, the effect of renewable energy consumption is obvious, and the grid operation is safe and reliable.

In order to show the influence of different factors on the temperature distribution more intuitively, the heat mixing index (HMI) is utilized to characterize the temperature distribution in the rack. All operation models are conducted with a three-dimensional, non-isothermal steady-state computational fluid dynamic (CFD). The CFD software contributes to the qualitative study of the effects of design parameters. Results show that the CRAC units layout has the most significant effect on the temperature distribution.

This paper presents the energy function to approximate the boundary of the synchronization stability domain of PMSG in the single PMSG-Infinite bus system, and the three direct methods are analyzed from the perspective of the stability domain. First, a reduced-order nonlinear model describing the dynamic synchronization characteristics of PMSG is established. Based on this model, the transient energy function of PMSG is derived by first integration method. Then, the boundary of the synchronization stability domain is approximated by the nearest UEP method, the CUEP method and the PEBS method. Finally, both simulation and experimental results are presented and thoroughly discussed so that it is possible to establish a fair comparison for the three direct methods.","PeriodicalId":308213,"journal":{"name":"2021 4th International Conference on Energy, Electrical and Power Engineering (CEEPE)","volume":"14 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-04-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132591411","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}
