This paper mainly focuses on the feasibility and economic analysis of solar water pumping systems in a remote village in India. Also, comparison of the same with conventional diesel-powered systems is carried out to study the pros and cons of both the systems. It is found from the analysis that the deployment of solar water pumping systems in an agriculture dependent nation like India has an upper hand in many aspects such as minimal environmental impacts, reduction of fossil fuel consumption, better profit margin etc. However, solar water pumping systems are still not treated as a viable option mainly because of the high upfront cost needed for the solar panels and pump. However, this can be easily negated via enhanced financial support schemes and incentives from the government. Considering all these factors, it is pertinent to deploy more of such projects on a larger scale all over the nation.","PeriodicalId":296432,"journal":{"name":"2018 Asian Conference on Energy, Power and Transportation Electrification (ACEPT)","volume":"47 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124777178","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}

Therefore, it is necessary to increase the use of renewable Energy to meet energy needs. Renewable energy is energy derived from sustainable natural processes. Indonesia located in the tropical area, it has a lot of potential ocean energy. OTEC (Ocean Thermal Energy Conversion) is one of many renewable energy sources from the ocean. OTEC or Ocean Thermal Energy Conversion is one of the latest technologies that used the temperature difference between deep and shallow seawater. OTEC system generally used ammonia (NH3) as working fluid. Ammonia is used because it has a relatively low boiling point compared to water. OTEC system consists of evaporators, turbines, generators, condensers, and pumps. This research, the authors focused on the design of lab-scale OTEC turbines. 2 stage turbine will be varied the tilt which is 0, 5, 10, 15, 20, 25, 30, 35, 40, 45, 50 degree. The computational fluid dynamics (CFD) method is used in this research to simulate the OTEC Turbine. Based on the simulation results, the highest efficiency and net power is a 2 stage 40 degree turbine with 57.45% of efficiency and 287.25 kW of generated power.","PeriodicalId":296432,"journal":{"name":"2018 Asian Conference on Energy, Power and Transportation Electrification (ACEPT)","volume":"38 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134348852","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}

A good grounding grid status is related to the stable operation of the power system. Therefore, when a corrosion problem occurs in the grounding grid, the grounding resistance will increase, and the discharge of electrical energy will become unsmooth. This may lead to spark discharge between devices. What’s worse, it may lead to device damage, resulting in a large area. Finally, it may affect the safe and stable operation of the power system. In grounding grid corrosion diagnosis, fault parameter identification method is one of the commonly used methods. By measuring the port resistance and performing inverse calculation to obtain the branch resistance change value, it also be-longs to fault parameter identification method. When measuring port resistance for ground grid corrosion diagnosis, since the digital DC bridge wire is not long enough, auxiliary wires need to be added between the digital DC bridge wire port and the down conductor steel. The contact resistance between the auxiliary wire and the down conductor steel will greatly affect the measured value of the port resistance, resulting in inaccurate inversion of the ground grid branch resistance. Therefore, in this paper, the influence of contact resistance on the corrosion diagnosis of grounding grid is studied by taking the grounding grid of the oil storage area as an example. The influence of the contact resistance on the inverse calculation is analyzed. The suppression method of the influence of the contact resistance in the corrosion diagnosis is also put forward and verified by the field test.","PeriodicalId":296432,"journal":{"name":"2018 Asian Conference on Energy, Power and Transportation Electrification (ACEPT)","volume":"152 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123319967","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, the combined use of a resistive-type superconducting fault current Iimiter (SFCL) and a superconducting magnetic energy storage (SMES) is proposed, and it is expected to improve the transient performance of a permanent magnet synchronous generator (PMSG) based wind turbine system under fault conditions. The SFCL is installed near the line side converter (LSC) of the wind turbine system, and its functions are to suppress the fault current and compensate the terminal voltage. The SMES is coupled to the wind turbine system’s DC-link, and it aims to alleviate the power difference between the generator side converter (GSC) and the LSC. Thus, the output power can be smoothed, and the DC-link overvoltage will be mitigated. Related theoretical modelling analysis is conducted, and further a detailed simulation model of 1.5 MW PMSG-based wind turbine integrated with the SFCL-SMES is built in MATLAB/SIMULINK. The simulations are performed to check the effects of the SFCL-SMES on handling the three-phase short-circuit. From the simulation results, the effectiveness of the proposed approach on augmenting the FRT capability and smoothing the power fluctuation of the PMSG can be well confirmed.","PeriodicalId":296432,"journal":{"name":"2018 Asian Conference on Energy, Power and Transportation Electrification (ACEPT)","volume":"32 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127776044","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}
