This paper presents a novel algorithm of tracking the power system equivalent parameters online with PSO based optimal quadratic form method, using local measurements at PCC. The algorithm uses three coherent measurements at PCC for impedance estimation without requiring synchronized measurements, and a nonlinear algebraic equation is gotten with three point phasor data. In order to solve the nonlinear equations with good performance, the nonlinear algebraic equation is transformed to an optimal quadratic form then. Later, an optimal quadratic form method based on particle swarm optimization (PSO) is provided for estimating the parameters by constructing the objective function of PSO according to quadratic form. Later, online tracking of equivalent parameters is realized by dynamic PSO estimation method. Verification studies, including calculating of static and dynamic equivalent parameters of the power system, are provided to verify the algorithm with Matlab/Simlink. Moreover, noise condition and error of measurements are investigated. The proposed algorithm has some advantages of convergence, precision and simplicity.","PeriodicalId":309998,"journal":{"name":"Proceedings of the 2020 3rd International Conference on Electronics and Electrical Engineering Technology","volume":"4 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-09-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133697443","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}

Many researchers have reported a method that uses blood smear to avoid overlapping of red blood cells (RBCs). Moreover, they have applied the refractive index of the blood plasma. However, the blood smear is not blood plasma, so that it cannot obtain the accurate depth information. In addition, it is difficult to measure the refractive index of the surrounding medium in every experiment. To solve this problem, in this paper, we propose a new method to record a hologram using a sample of a mixture of blood and a uniform microsphere. We have already known the size of the microsphere in the experiment. Thus, we can modify the refractive index of the surrounding medium. Finally, we can measure the accurate depth information of the specimen using the modified refractive index of the surrounding medium. The proposed method can be used not only in RBCs but also in the study of cells or microbial.","PeriodicalId":309998,"journal":{"name":"Proceedings of the 2020 3rd International Conference on Electronics and Electrical Engineering Technology","volume":"22 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-09-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124687104","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}

However, when the nonlinear loads are unbalanced, the grid currents compensated by SAPF are still unbalanced and distorted even an accurate current detection method is adopted. The reason is that when SAPF compensates the unbalanced loads of grid, the DC-link voltage will contain the second-order harmonic which has influence on the d-axis reference of SAPF's current control loop. Then the output of the SAPF will contain extra third-order harmonic and fundamental negative sequence currents, which make grid currents distorted and unbalanced. In this paper, in order to overcome the problem of poor filtering and dynamic performance by using traditional PI control for DC-link voltage, a MAF-PI controller which combines a moving average filter (MAF), a phase-lead compensator (PLC) and a PI control into DC-link voltage control loop is proposed. This strategy realizes the accurate harmonic currents compensation and excellent DC-link voltage dynamic response of SAPF for unbalanced loads. The effectiveness of the proposed strategy is verified through simulation results.","PeriodicalId":309998,"journal":{"name":"Proceedings of the 2020 3rd International Conference on Electronics and Electrical Engineering Technology","volume":"8 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-09-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122928636","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 prolongation of drilling period will not only increase the operating cost, but also affect the realization of exploration and development plans. In order to improve the drilling speed of hard to drill formation in P block and shorten the drilling period, a set of formation drillability evaluation method is established in this paper. This method is mainly based on the P-wave and S-wave velocity of drilling parameters to calculate the rock mechanics parameters of the formation, and the drillability parameters of the formation are calculated by using the logging data. The rock grades of rock drillability, hardness, plasticity and shear strength are clustered into a comprehensive rock grade value, so as to quantitatively describe the differences of rock drilling characteristics and provide a reliable basis for bit selection. In this paper, the established evaluation method of formation drillability is applied to well A in P block to obtain the mechanical properties formation rock, drillability profile of roller bit and PDC bit in this area. Based on the above results, the optimal type of drill bit is selected, which provides scientific basis for design and construction of drill bit in difficult drilling formation.","PeriodicalId":309998,"journal":{"name":"Proceedings of the 2020 3rd International Conference on Electronics and Electrical Engineering Technology","volume":"18 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-09-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130094339","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}
