In the charging station design, the proper distribution transformers that delivery reliable power from utility to the station are essential and important. To ensure economic and reliable operation of the charging station, the paper proposes a methodology for the PEVs charging station transformer design. A set of dynamic thermal energy models that describe the relationship between the transformer winding temperature and charging station load profile is derived according to ANSI/IEEE standards. The base load, PEVs demand, power quality, ambient temperature, transformer rating and connection all are taken into account. The models are then used to analyze PEVs charging impact on transformer loss-of-life and determine the proper transformer capacity and connection. The proposed method provides a better knowledge of the transformer effects and can be used for evaluating the level of PEVs that might be accepted on a distribution transformer. The models developed can also be used for determining proper transformers in the design of charging station distribution systems. The field testing results of a practical charging station for PEVs pilot projects in Taiwan confirm the validity of the proposed method.","PeriodicalId":446068,"journal":{"name":"2014 IEEE Industry Application Society Annual Meeting","volume":"2 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-12-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114597162","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 performance of flux and speed observer is strongly influenced by the deadtime and inverter non-linear error at the low speed range. In most applications, the effect of deadtime can be offset by compensating the pulsewidth of PWM signal. However, the inverter non-linear error, such as voltage drop in switching devices, is difficult to compensate when the reconstructed phase voltage is utilized as the input of the observer, because it is not a fixed value. To solve the problem, in this paper the effect of non-linear error upon stator current estimation error is analyzed. A novel compensation method of non-linear error through the stator current estimation error is proposed. The proposed method separated the compensation of non-linear error from the deadtime compensation. Furthermore the nonlinear error can be identified directly off-line by the self-tuning method at the drive start-up and stored in the look-up-table. The experimental results demonstrate the feasibility of proposed method especially in the low speed range.","PeriodicalId":446068,"journal":{"name":"2014 IEEE Industry Application Society Annual Meeting","volume":"44 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-12-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"117157592","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 same surface potential measurement technique is employed to characterize the charging state of insulating materials, such as films or non-woven media. The aim of the paper is to give some elements of answer to the following question: What significance can be attributed to the value displayed by the electrostatic voltmeter when the charge is non-uniformly distributed at the surface of the bodies examined by the probe and no constant surface potential can be defined? The measurements were performed for some simple experimental models that simulate surface potential non-uniformity. Thus, a copper wire, a copper rod, and two aluminium strips, connected to a high-voltage supply (V = 875 V) were located at 5 mm above a grounded metal plate. The vibrating capacitive probe was placed at various distances h above the grounded plate and at various distances x from the axial plan of the high-voltage strip/rod/wire - grounded plate system. Different V(x) curves obtained for each of the situations under study, pointing out that the value displayed by the instrument depends on the distribution of the potential across the surface examined by the probe. A commercial computer program based on the superficial charge simulation method was employed for the numerical analysis of the electric field in a simplified model of the geometric system formed by the probe, the high-voltage strip/rod/wire, and the grounded plate. The potential that anneals the electric field at the surface of the probe (to simulate its principle of operation) was calculated by an iterative method. A good agreement was found between the results of the numerical simulations and the experimental data.","PeriodicalId":446068,"journal":{"name":"2014 IEEE Industry Application Society Annual Meeting","volume":"228 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-12-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116490929","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}
