The peak voltage of switch decreases to about 3.4 times of the input DC voltage of class-E inverter, and varies less than 5% with load variation.

Of particular interest in this study is the detection and classification of power electronics loads, as they impose specific challenges in their detection and correct disaggregation (classification).

The present optimal reactive power compensation allocation methods mainly focus on the safe reliability of system, but the economic value affected by the voltage sag is insufficiently considered. This paper proposes an optimal allocation method which considers the huge economic loss of voltage sags and focuses on return on investment index of high-cost STATCOM. Firstly, based on quality engineering theory, voltage sag severity index and voltage sag economic loss index are proposed. Secondly, by comparing the voltage sag economic losses before and after the installation of STATCOM, this paper puts forward STATCOM return on investment index to assess the economic benefit of different installation capacity. Finally, based on above economic benefit evaluation indexes, an optimal reactive power compensation allocation method is proposed. The proposed method can both ensure the safe reliability of system and achieve the optimum economic benefit. A real power grid of Hunan is simulated using BPA. The simulation results verify the validation of the proposed method.","PeriodicalId":446770,"journal":{"name":"2018 IEEE International Power Electronics and Application Conference and Exposition (PEAC)","volume":"76 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132501743","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 frequency dependent characteristic curve of leakage inductance in a wide frequency band is presented using analytical method, which can be divided into three regions and verified by comparing with finite element simulation. Also, the concept of turning frequency is proposed and the changing trend of turning frequency is studied for transformers with varying-thickness copper foils. Below the turning frequency, the simulation model simplification is implemented by replacing multi-layer copper foil with single-layer copper foil with the same thickness, which is verified by comparing the three-dimensional finite element calculation result with the measurement.","PeriodicalId":446770,"journal":{"name":"2018 IEEE International Power Electronics and Application Conference and Exposition (PEAC)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130848228","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 verify the validation of the model, the comparison among the calculation results, simulation results and the measurement results based on the LM5034 application are conducted. It is shown that the proposed open loop transfer function on this converter is very useful due to the good agreement with both the simulation result and measurement result.

It provides excitation and demagnetization voltage for phase windings, and its performance will directly affect system performance. A new type of five level power converter is proposed in this paper. The DC side is connected in series with two capacitances. The midpoint of the capacitances is connected to each end of the winding through two switches respectively, and it can work in five different operating modes by controlling the ON-OFF states of switches. Compared with the traditional power converter, the proposed power converter provides more voltage selection, which is beneficial to improve the output performance of the motor. Finally, the control performance of the proposed topology is compared with that of the traditional topology by simulation and experiment. The control method is direct instantaneous torque control. Simulation and experimental results show that the new five level power converter has better torque ripple suppression effect.","PeriodicalId":446770,"journal":{"name":"2018 IEEE International Power Electronics and Application Conference and Exposition (PEAC)","volume":"903 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123266313","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}
