Fast and accurate location of forced oscillation source is the key to suppress power system forced oscillation. In order to improve the accuracy and anti-noise ability of forced oscillation source location based on dissipation energy flow, this paper proposes a forced oscillation source location method based on complete ensemble empirical mode decomposition with adaptive noise(CEEMDAN). This method first conducts CEEMDAN on the measurement of the generator, decom-poses the measurement into the intrinsic mode function (IMF) components with different oscillation modes, and extracts the IMF components representing the forced oscillation mode from many IMFs according to the IMF energy weight. On this basis, the calculation method of dissipation energy flow based on CEEMDAN is given, and the accurate location of forced oscillation source is realized according to the calculated dissipation energy flow. Finally, the proposed method is applied to the simulation data of WECC-179 bus test system for analysis and verification, and the relevant results verify the accuracy and robustness of the proposed method.","PeriodicalId":304779,"journal":{"name":"2022 9th International Forum on Electrical Engineering and Automation (IFEEA)","volume":"37 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":"133250220","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 order to identify the hydrophobicity level of composite insulators accurately, a method based on RS-RepVGG is proposed in this paper. The algorithm is based on RepVGG-B0. Firstly, during training, a residual branch across the nonlinear layer is added to RepBlocks to solve the depth constraint problem of RepVGG model without affecting the calculation efficiency of the model. Secondly, the reserved and merged (RM) operations are used to remove the added residual connections equivalently and the re parameterization method is used to decouple the network branches with VGG reasoning structure. Finally, based on this model, spectral nonlocal block (SNL) is introduced to replace the se attention mechanism module at stage2 in the original network, so that the network can capture long-range correlation more flexibly and robustly. The test was carried out in the water spray image data set of composite insulator of Christos-Christodoulos A. Kokalis team. Compared with repvgg-b0, rs-repvgg-b0 increased the model volume by 12.6%, but the floating-point calculation ability of the model was improved by 7.7%, the average recognition accuracy was improved by 2.72%, reaching 97.86%, and the uncertainty of misjudged sample results was not more than ± 1 HC level, which was in line with IEC TS 62073 standard. The experimental results show that, compared with many other existing methods, the RS-RepVGG based composite insulator hydrophobicity grade recognition method proposed in this paper has the advantages of high recognition accuracy, small size and strong floating-point computing ability, and meets the requirements of composite insulator hydrophobicity grade determination.","PeriodicalId":304779,"journal":{"name":"2022 9th International Forum on Electrical Engineering and Automation (IFEEA)","volume":"83 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":"126163085","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}
