They are increasingly widely used in power grids. However, the large-capacity condenser has a large volume and complex structure and is prone to faults, which urgently requires research on fault feature analysis and diagnosis technology. This article analyzes the features of large-capacity synchronous condensers and their engineering advantages, such as increasing the short-circuit ratio of the receiving power grid, improving the transmission limit power, working in a forced excitation state for voltage support in the event of a commutation failure at the UHVDC receiving end, absorbing excess reactive power to suppress sudden voltage rise during DC blocking, and providing dynamically adjustable reactive power support for the AC power grid through flexible switching of late or leading phase states. This article provides common faults, such as mass imbalance, misalignment, friction, oil film oscillation, etc. At the same time, the fault characteristics are analyzed using computer simulation analysis, laboratory simulation analysis, and on-site measurement testing methods. A standard fault diagnosis method for synchronous condensers is proposed on this basis, utilizing fault pattern recognition and credibility evaluation. By establishing a library of fault models for the synchronous condenser and employing time-domain and frequency-domain signal analysis techniques, the credibility and nature of the fault are determined by calculating the instantaneous values and rate of change of the sampled signal using eigenvalues. Through the comparison and analysis of pertinent standards and historical data, the severity of the fault is ascertained, along with the trend and severity of the problematic synchronous condenser. The findings of this study have additionally advanced the progress of fault diagnosis technology for synchronous condensers with large capacities.","PeriodicalId":518671,"journal":{"name":"2024 IEEE 4th International Conference on Power, Electronics and Computer Applications (ICPECA)","volume":"32 1-2","pages":"87-91"},"PeriodicalIF":0.0,"publicationDate":"2024-01-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140530106","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}

Addressing these concerns, this paper proposes a power data privacy protection method based on secret sharing. Firstly, the method utilizes nodes elected through the leader election algorithm in the Raft protocol to replace traditional aggregators for data verification and aggregation operations. This eliminates the need for a trusted third party and enables fault tolerance for intermediate nodes. Secondly, the method incorporates a dynamic secret sharing homomorphic scheme to achieve secure data aggregation, ensuring that even internal attackers can only access aggregated data without obtaining individual power consumption details. Moreover, the scheme employs batch verification techniques to enhance signature verification speed. Experimental analysis indicates that this method exhibits lower computational and communication overhead compared to alternative approaches.","PeriodicalId":518671,"journal":{"name":"2024 IEEE 4th International Conference on Power, Electronics and Computer Applications (ICPECA)","volume":"10 3","pages":"1366-1370"},"PeriodicalIF":0.0,"publicationDate":"2024-01-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140530310","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 tower solar thermal power station, the arrangement of the heliostat field directly affects the power generation efficiency of the tower power generation system as well as the working cost. Therefore, this paper presents a model based on geometric relationship and particle swarm algorithm for the optimization of the heliostat field arrangement, mathematical modeling and calculating cosine efficiency, truncation efficiency, etc., and effectively improves the output thermal power as well as the optical efficiency of the heliostat field. Geometric planning is utilized to determine the location of the absorption tower, the coordinates of the heliostat arrangement and other layout parameters to optimize the layout of the tower solar system. Drawing on the idea of clustering, the model analyzes the characteristics of the heliostat mirrors in the same region, uses same or similar parameters to minimize the cost of computation, improving the overall optical efficiency of the mirror field. The particle swarm algorithm is utilized to solve the parameters such as mirror length and mirror width of the heliostat to get the suitable size of the heliostat for the heliostat mirror field. After completing all the calculation and optimization steps, the final solution of the model is carried out in this paper. The layout scheme of the heliostat field optimized by the implementation of the model gets a significant performance improvement. Specifically, the average annual thermal power output of the heliostat field is improved by 33.2309 MW, while the average annual optical efficiency is also improved by 43.2%. These improvements effectively enhance the power generation efficiency of the whole system, confirming the effectiveness of the optimization method in this paper.","PeriodicalId":518671,"journal":{"name":"2024 IEEE 4th International Conference on Power, Electronics and Computer Applications (ICPECA)","volume":"6 2","pages":"365-373"},"PeriodicalIF":0.0,"publicationDate":"2024-01-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140530460","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}
