It has a potential for wide application in power generation systems. Non-ideal characteristics such as symmetrical and asymmetrical dips in the grid voltage are inevitable in power generation systems. Running BDFIG in a non-ideal grid will produce low-order harmonic oscillation, which will cause the distortion in the winding voltage, resulting in serious overvoltage and overcurrent faults in motor winding, reducing the reliability of the entire power generation system. In order to provide more targeted protection for BDFIG under non-ideal grid operating conditions, this paper establishes the BDFIG model with the non-ideal power grid and analyzes its working characteristics. Firstly, establish the BDFIG model under the ideal grid and obtain the voltage characteristics of the control winding from analysis of when the power grid fails; Secondly, establish the BDFIG model under the non-ideal grid and analyze from two cases of balanced grid with low harmonic voltage and unbalanced grid with low harmonic voltage respectively. Thirdly, the relational equations of the positive and negative sequence components are derived respectively, which provides a theoretical basis for the control of positive and negative sequence components; Finally, the characteristics of BDFIG under non-ideal grid are simulated and verified by Matlab/Simulink.","PeriodicalId":118143,"journal":{"name":"2022 5th International Conference on Energy, Electrical and Power Engineering (CEEPE)","volume":"15 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-04-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128065878","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}

If all nodes in the distribution system are equipped with measuring devices, the state estimation problem will be greatly simplified, but this configuration method is difficult to achieve due to economic constraints, so it is necessary to study the optimal distribution scheme of measuring devices. This paper presents an optimized distribution scheme for new distribution measurement terminals, establishes the mathematical model of terminal distribution based on 0-1 integer programming, and formulates the principle and process of node configuration based on tree graph search technology. Based on the measurement characteristics of the Internet of things measurement terminal device applied to power distribution, the calculation methods to make the zero injection nodes and connected nodes observable in the network are deduced, and the terminal distribution methods suitable for large and small-scale systems are proposed. In order to meet the requirements of complete observability and economy of power distribution system, the proposed two methods are configured and compared in different common network architectures.","PeriodicalId":118143,"journal":{"name":"2022 5th International Conference on Energy, Electrical and Power Engineering (CEEPE)","volume":"46 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-04-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128904892","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}

Although the use of electromechanical transient simulation and electromagnetic transient hybrid simulation technology or electromagnetic transient and dynamic phasor hybrid simulation technology can retain high simulation accuracy, it is not conducive to the model mechanism analysis and the control operation. In addition, the MMC average model is also used for AC and DC transient simulation. The average modeling uses controlled power sources to describe the average response of the converter, which can also be employed to the transient simulation. Due to the modeling properties of the ABC coordinate system, the average model is only suitable for time-domain simulation. The dynamic phasor modeling method employs the d−q axis coordinate system to analyze the MMC steady-state and research the small-signal stability. The order of each component in the d−q axis coordinate system model can be selected according to the required accuracy. Thus, the MMC dynamic phasor modeling scheme has widespread application in MMC-HVDC stability research, electromechanical transient simulation and controller design, etc. This article will establish an MMC dynamic phasor model to analyze the dynamic characteristics of system circulation.","PeriodicalId":118143,"journal":{"name":"2022 5th International Conference on Energy, Electrical and Power Engineering (CEEPE)","volume":"129 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-04-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122325125","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 reduce the adverse effects of high permeability of PV, the power system has put forward relevant requirements for PV to participate in peak and frequency modulation. A method to solve the problem of PV peak and frequency modulation is to use Flexible Power Point Tracking (FPPT) strategy which is photovoltaic power generation system (PVPGS) operates below the maximum Power Point, with active Power reserve. Most of FPPT strategies operates in the right-sides of Photovoltaic system, instead of the left-side. However, the right-sides operation mode has its defects, and the left-sides operation mode has its advantages. In this paper, the FPPT strategy of photovoltaic power generation system is classified and briefly described, and the tracking performance of FPPT strategy in different working conditions is studied, and its principles are analyzed, which provides a benchmark for researchers and engineers to choose suitable FPPT operation mode for specific applications. The simulation results show that the PVPGS is more stable when running on the left side of the photovoltaic characteristic curve, while it is difficult to give consideration to the corresponding dynamic speed and steady-state accuracy when running on the right side. The single-stage PV system have the problem of power reverse peak when running on the left side of the PV characteristic curve.","PeriodicalId":118143,"journal":{"name":"2022 5th International Conference on Energy, Electrical and Power Engineering (CEEPE)","volume":"21 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-04-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132410099","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}

Unlike pure cable lines, the sheath voltage of hybrid overhead-cable lines could exceed the power frequency withstand voltage of outer-sheath under some circumstances. Its amplitude is closely related to the earth potential rise at the connection point of overhead lines and cables. This paper employed PSCAD-EMTDC to study the power frequency sheath overvoltage of a hybrid overhead-cable line type in the case of single-phase-to-ground fault of the overhead line terminal, where the overhead line was inserted between the cable lines applied with various sheath bonding methods. And the influence of the grounding resistance of the terminal tower and the earth continuity cable on the sheath induced voltage was also discussed. Simulation results indicated that, the earth potential rise and sheath voltage of single-point bonded cables exceed 25 kV in serious cases. Compared with the cables with sheath single-point bonded, the earth potential rise at the connection point was much lower, below 10 kV, when the overhead line was connected to the cables with sheath cross-bonded, and the grounding resistance of the terminal tower had little influence on the earth potential rise. Besides, the installation of earth continuity conductor had a markedly positive effect on the power frequency withstand performance of cable outer-sheath and sheath voltage limiters for this hybrid line type.","PeriodicalId":118143,"journal":{"name":"2022 5th International Conference on Energy, Electrical and Power Engineering (CEEPE)","volume":"9 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-04-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116841558","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}
