Starting from the vibration and noise of the reactor core, the vibration and noise signals of the core under the normal working conditions of power frequency and the excitation of harmonic and DC magnetic bias abnormal working conditions are measured by establishing the vibration and noise test platform of the core model, and the correlation analysis and comparison of the vibration and noise data after the Fourier transform are carried out by using the three-dimensional waterfall diagram. The test results show that the frequency-domain distribution of the noise signal of the iron core under different excitation varies significantly. The noise signal can represent the operation state information of the iron core reflected by the vibration signal, and the Pearson correlation coefficient of the vibration and noise data reaches 0.701, showing a strong positive correlation.","PeriodicalId":339798,"journal":{"name":"2020 IEEE 4th Conference on Energy Internet and Energy System Integration (EI2)","volume":"35 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-10-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122419494","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 simulation results of this paper show that: the direction of the electric power in the single arm current limiting is mainly distributed axially symmetrically outward, and symmetrically about the middle of the vertical height, the radial force from the inside to outer encapsulation is gradually reduced, and the outermost side has a weaker contrat tendency. In general, each encapsulation has an outward expansion tendency. At the same time, the temperature distribution of the high coupled split reactor shows that the upper region is higher than the lower region, and the intermediate encapsulation is higher than the encapsulation trend of the two sides. The highest hot spot temperature is 10-cated in the upper region of the middle of the high coupled split reactor. The research results provide a theoretical basis for the design and optimization of the 550kV high coupled split reactor test scheme.","PeriodicalId":339798,"journal":{"name":"2020 IEEE 4th Conference on Energy Internet and Energy System Integration (EI2)","volume":"92 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-10-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114505753","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}

This paper proposes an event-driven fast frequency response (EFFR) approach to counter frequency decline after large power disturbances. Based on the data from the wide area measurement systems, a centralized control framework is established to perform the EFFR. Then, the reference power for EFFR can be determined promptly via monitoring active power deficits. Considering the control costs and power reserves, a utility index is created to quantify the priority of each unit to participate in EFFR, on which the reference power is distributed. Furthermore, a recovery strategy is designed to restore the normal operation states of units when the power system enters the quasi-steady state. According to a droop slope, units exit the EFFR mode in sequence, of which the distributed reference power decreases gradually. A case study is presented to validate the feasibility and effectiveness of the proposed approach.","PeriodicalId":339798,"journal":{"name":"2020 IEEE 4th Conference on Energy Internet and Energy System Integration (EI2)","volume":"212 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-10-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114572535","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}

Then, how to coordinate the energy hubs in the systems to meet this challenge has become a key issue. Although the chance-constrained method is a workable solution, the determination for chance-constraints is complex, which leads to great difficulty in solving the model. Therefore, the steady-state security region (SSSR) method is applied into the optimization in this paper. First, a SSSR-based model for IESs is established. Second, the power inputs of energy hubs are set as variables and linear chance-constrained expressions are fast generated by using a Cornish-Fisher expansion-based method. Because the variables in both constraints and the objective are identical, the computation of optimization is greatly reduced. Third, a linear model is established with the minimum total cost of IESs, and the calculation speed is very fast when using the linear programming method. Optimization results for the test combined IEEE 33-node power system with 13-node gas system and the test combined PG&E 69-node power system with Belgian gas system are given to verify the effectiveness of the proposed method.","PeriodicalId":339798,"journal":{"name":"2020 IEEE 4th Conference on Energy Internet and Energy System Integration (EI2)","volume":"130 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-10-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121963156","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}
