At present, Koh Tao uses electricity from diesel power plants resulting in high costs in maintenance, fuel, and electricity, causing PEA to bear many losses each year. Investment in the construction of a distribution system linked by submarine cable is a project that uses a lot of investment cost in constructions and in each construction also affects the environment as well. Thus, there must be an effective method of calculating the investment value to ensure that the investment projects are appropriate and cost-effective throughout the life of the asset. This paper presents the analysis of the financial feasibility of the submarine cable project to ensure that it will have economic benefits and be effective throughout the asset utilization period with life-cycle cost analysis. In this paper, three alternatives are simulated, and the life-cycle cost (LCC) of all three alternatives are calculated. Then, the analysis is performed to find which options are worth the most investment. Common network asset indices methodology (CNAIM) is applied to determine the age of the submarine cable used in the project. In addition, this method can be used to find the probability of failure (PoF) of the submarine cable which is an important parameter and is used to calculate in the LCC model to achieve the purpose of this paper.","PeriodicalId":241317,"journal":{"name":"2019 IEEE PES Asia-Pacific Power and Energy Engineering Conference (APPEEC)","volume":"16 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131516049","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 light absorption enhancement and the visual transparency are investigated for a wide range of NC sizes (40-100nm) as well as different absorber layer thickness (in the range of 100-300nm) with a variety of Br-compositions in the perovskite layer. In addition, detailed study of localized field enhancement and scattering of the NCs are performed. It is found that, by tuning proper NC size and absorber thickness along with its Br-composition, optimization in absorption enhancement and transparency can be achieved for Cu plasmon NCs, in such a level whih is very much comparable with Ag plasmon NCs.

It has a specially designed filtering winding and has a good multi-port harmonic suppression function. Based on the coupled inductance parameters and the transformer model, this paper reveals the special connection of the coupling inductor of the novel filtering transformer. By establishing the voltage-current conversion relationship equation of the novel filtering transformer, the protection principle applicable to the novel transformer is expounded. Furthermore, the protection action equation of the novel filtering transformer is derived, and then the internal fault identification criterion is proposed. The protection principle is based on the corresponding relationship between the internal structure of the transformer and the coupled inductance parameters. Combined with the characteristics of the coupled inductor, it can identify internal faults and at the same time avoid the external fault of the transformer. Finally, the correctness and reliability of the protection principle are verified by building a MATLAB simulation model.","PeriodicalId":241317,"journal":{"name":"2019 IEEE PES Asia-Pacific Power and Energy Engineering Conference (APPEEC)","volume":"234 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134020130","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}

Assessing the health condition of high voltage cables is a crucial task to prevent system fault. Traditionally, the sound condition of high voltage cables is proven by high voltage testing before commissioning. However, high voltage testing may not reveal all defects on the cable or even developing new defect. Various condition monitoring methodologies have been implemented on power transformer and gas-insulated switchgear for real time condition monitoring. Nevertheless, condition monitoring on cross-linked polyethylene (XLPE) cables is still challenging. We have developed a solution to assess the insulation condition of energised XLPE cable by partial discharge (PD) measurement using high frequency current transformer (HFCT) through link-boxes. The insulation condition can be diagnosed by (phase-resolved PD) PRPD pattern, and source of PD can be traced from the frequency of PD impulse. The effectiveness of PD measurement by HFCT is demonstrated by real cases.","PeriodicalId":241317,"journal":{"name":"2019 IEEE PES Asia-Pacific Power and Energy Engineering Conference (APPEEC)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130393006","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}

Different cable transmission modes were analyzed for the effect of the sensor for leakage current separation, and a method of installing simultaneous sampling current monitoring units was proposed.
