The article provides a brief review of methods for generator parameters identification and a machine learning method based on convolutional neural networks (CNN) that is implemented. To prepare a training sample, an analysis of the real generator under study is carried out, in particular, characteristic modes of its operation, specifics and variability of disturbances. Based on this analysis, the equivalent of a real electrical network is modeled with the option of simulating similar real events. A deep learning approach using a CNN is used to identify parameters. The final result of this work is the test of a machine learning model based on synthetic data. As a result, the average error in parameters identification according to mean absolute percentage error indicator was 2.8%.

At the moment, on the territory of the Russian Federation, the assessment of the condition is carried out during preventive maintenance and repairs and subsequent analysis of the measured values. This approach to determining the condition is associated with significant operational costs, limited speed of information transmission from branches of operating organizations to analytical centers and the presence of errors on the part of personnel when removing data on the condition of equipment. Also, the normative and technical documentation regulating the implementation of preventive measures was developed several decades ago and does not take into account either the change in the nature of the load on the equipment, or the technical condition and residual life of the equipment. For new equipment, the regulations developed at that time do not take into account the fact that new components with different characteristics and properties, are now used in the equipment.","PeriodicalId":413852,"journal":{"name":"2022 5th International Youth Scientific and Technical Conference on Relay Protection and Automation (RPA)","volume":"42 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-10-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131923986","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 leads to a complication of the form of presentation of the developed PACS, which ultimately makes it much more difficult to analyze and control them for compliance with the current rules and regulations. Obviously, in such conditions, if designing solutions are used without preliminary comprehensive testing using digital models of an electric power network, can lead to a significant increase in the period for commissioning, but more importantly, increases the risk of incorrect operation of PACS while exploitation.At present, carrying out such tests is a rather time-consuming and technically complex process, which includes creating a model of a power system fragment and connecting real PACS devices to it, forming a set of test scenarios, conducting tests and subsequent processing of test results.In addition, with an increase in the number of digital PACS devices at a substation and an increase in the degree of its \"digitization\", the number of tests that need to be performed to analyze the correct operation of the devices and the system as a whole increases, and the methods for conducting tests become more complicated. Making changes to the operating parameters of the electric power network model, regularly adjusting the settings of the PACS devices, as well as adding new test scenarios, lead to the need to repeat the tests many times.The current level of development of the PACS hardware and software and the emerging global trends towards the universality of their execution, along with the expansion of the use of digital technologies, open up new opportunities for automating the processes of testing the PACS implemented according to IEC 61850, including testing a designing solutions.","PeriodicalId":413852,"journal":{"name":"2022 5th International Youth Scientific and Technical Conference on Relay Protection and Automation (RPA)","volume":"59 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-10-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115898173","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}

One of the promising applications of the synchrophasor technology is real-time monitoring of power system components such as a synchronous generator (SG). The paper is dedicated to estimating hydrogenerator synchronous parameters through synchrophasor data captured under steady-state conditions. The synchronous reactances along the d- and q-axes are important to verify, as they go into equivalent circuits for steady state analysis and stability margin assessment.A few different models are developed and tested out with simulated data as well as real-field synchrophasor measurements collected at one of the Russian hydroelectric power plants. Two different approaches to measurement error modeling have been taken, and the results on simulated data turned out fairly good, with the standard deviation for xd of less than 1 %, and for xq of at most 4 %. For a \"black box\" simulation, five different operating states captured by a phasor measurement unit on a real hydrogenerator were selected and used as input data to the developed models. The result for the xd synchronous reactance was acceptable while for xq was not. Possible ways to make the estimation results more accurate and robust are suggested.","PeriodicalId":413852,"journal":{"name":"2022 5th International Youth Scientific and Technical Conference on Relay Protection and Automation (RPA)","volume":"34 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-10-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129843504","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}
