The power electronic converters role is important In between sources and load. The load may be linear and non-linear in nature, so converters performance decides the efficiency of the system. Proper controller can switch the converter in the desired time and improve the system performance and stability. Many controllers are suggests to control the converter to get better performance in at output side. The proposed system also has boost converter, bidirectional DC-DC converter and inverter for grid and wind energy integration. The boost inverter/buck rectifier in this system is controlled by ANFIS controller is for better output, boost and bidirectional DC-DC converters are controlled by PID controller in closed loop. Overall operations are based on modes main controller speedgoat, which is control the system operation in different modes. Any variation happening in the input, storage and load parameters speedgoat changing the mode and operate the system is in effective way. Based on the system conditions speedgoat generates control signal for the control breakers, these control breakers changing modes of operation. ANFIS, PID and speedgoat are the three controllers combined together which harness maximum wind energy and this system is applicable for both linear and non-linear loads in domestic applications.","PeriodicalId":239682,"journal":{"name":"Modelling, Measurement and Control A","volume":"2020 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-09-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114909802","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 the transmission system, Transformers have the highest population with the highest energy efficiency amongst all other electric devices. Transformers practically operate throughout the year at various load conditions. Therefore, the Total losses in transformers are core loss/no-load loss + IR Losses + stray losses (due to the linkage of stray flux in structural parts like core clamping structure, tank, etc). Out of these losses in transformer, Stray loss (undesirable) component is more than 20% of the total load loss. Loss capitalization is an important factor in Transformer owning cost which depends on losses and other parameters. Therefore, reduction of stray losses gives the advantage in lower owning cost as well increase in the transmission line efficiency. The paper presents the use of UDEL (Unimpregnated densified electrical grade laminated) wood as a core clamping structure to reduce stray losses and subsequent reduction in heating effects with further advantage in owning cost of the transformer. Development of 15 MVA, 66/11.55 kV transformer with use of UDEL wood core clamp structure against conventional mild steel core clamp is discussed. Results show that there is a 28.2% reduction of stray loss and 4.5% reduction of total losses using the proposed method. The use of UDEL wood also reduces the partial discharges in magnitude (average 27% reduction) by avoiding magnetic material in the vicinity of high voltage leads and yoke shunts. Structural analysis was also performed using Finite Element Method (FEM) based software to check the suitability of wood core clamp structure under dynamic short circuit test condition. To ascertain the ability of UDEL wood core clamping structure, dynamic short circuit withstand test is conducted at the national laboratory and transformer has successfully withstood the test.","PeriodicalId":239682,"journal":{"name":"Modelling, Measurement and Control A","volume":"110 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-06-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123691216","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 this paper we are not praising for the growth of the country, no doubt for the growth but we want to focus on the traffic system control. Day to day traffic is increasing in which the big problem is faced for the safe passage for the ambulance vehicle’s escape or some other person who is in need of urgent work anywhere apart from medical facilities. We heard many patients leads to death in the ambulance and doctor says ‘‘it’s too late, if you could reach at least 10minutes before then the patient could have been saved his/her life’’. So here we focused in paper to facilitate the emergency services (only concerned to patient’s ambulance) signal free. This will be possible by using the telecom technologies along with city traffic control stations to implement the things made easier for the signal free passage to escape of ambulance from the traffic lights or streets means the ambulance would not stop in the traffic jams. This can be made possible using VANET-LTE advanced technology.","PeriodicalId":239682,"journal":{"name":"Modelling, Measurement and Control A","volume":"100 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-06-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122909564","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}

Determination of optimal locations, results in more economical benefit of these equipments. The majority of the works presented in the literature try to satisfy this goal, using classical load flow methods, such as NewtonRaphson approach or the back-forward method. However, these classical methods may suffer from some serious deficiencies. Namely, the first method is faced to the risk of divergence in distribution systems and the second is time consuming. Moreover, both methods impose quite significant complexity. The method presented in this paper employs a load distribution technique in addition to the genetic algorithm solution, enabling the investigation of simultaneous effects of the distributed generation and voltage regulator on a distribution feeder. In the proposed algorithm, an objective function composed of power losses and voltage deviations is used to obtain an optimal location of the above mentioned equipments (DGs and VRs) and the efficient size of the distributed generation system. The proposed idea has been examined for the IEEE 33-Bus test system and its favorable efficiency is confirmed.","PeriodicalId":239682,"journal":{"name":"Modelling, Measurement and Control A","volume":"33 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-06-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130557961","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 this paper, circularly polarized reconfigurable patch antenna operating at 2.3 GHz band is presented. The antenna consists of a radiating patch incorporated with a square-shaped slot at its center. Ultra-miniature switches are placed in the gap region of the slot in the radiating element for reconfiguring antenna geometry and thereby achieving polarization reconfiguration. The antenna achieves either left-hand polarization or right-hand polarization depending upon switching of the corresponding pair of MEMS switches. The performance of the antenna is validated using high-frequency structure simulator tool and the results are compared with other conventional antennas. The antenna gives a good impedance bandwidth of 70MHz between 2.295GHz – 2.365GHz in the operating band with a peak gain of 5dBi. It also achieves wider 3dB axial ratio beamwidth od 140 along with good cross-polarization isolation of -12 dB for RHCP and -13 dB for LHCP configurations at its operating frequency and hence better suitable for application in areas of modern wireless communication.","PeriodicalId":239682,"journal":{"name":"Modelling, Measurement and Control A","volume":"6 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-06-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131761840","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}
