There are so many reports of system failures caused by porcelain insulator failures especially in highly polluted areas. Due to superiority in repel of contaminated solution, polymeric insulators set to replace the ceramic insulators in transmission and distribution lines. The objective of the current paper is to study effects of aging on leakage current characteristics and housing conditions of silicone rubber polymeric insulators under artificial tropical climate. Polymeric insulator sample was put in a chamber and have been exposed to ultraviolet radiation by UV lamp and penetrated in a vessel contain contaminant solution according to ANSI C-29 13-2000. The electrical properties as well as changes on the surface were investigated by measuring magnitude, waveform, THD, and cross product of leakage current. Visual observation of the hydrophobicity class of silicone rubber’s sheds was observed using a camera. To know the relations of hydrophobicity class with leakage current characteristics, samples were tested in a chamber under variety of salt-fog and pollution conditions according to IEC 60507. The housing conditions of silicone rubber polymeric insulator were investigated using SEM-EDX method. Experimental results indicated that UV radiation, corona activity, and contaminant solution are greatly affect the aging of the insulators. In addition, combination of high pollutant and humidity extremely increase the magnitude and THD of leakage current especially for sample after aging.","PeriodicalId":6677,"journal":{"name":"2019 2nd International Conference on High Voltage Engineering and Power Systems (ICHVEPS)","volume":"19 1 1","pages":"1-6"},"PeriodicalIF":0.0,"publicationDate":"2019-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"83090324","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}

But it is also exposed by electrical faults which lead the aging or degradation of electrical insulation. Therefore, electric arc aging is one of the most important factors that should be considered. It is very important to analyze the effects of accelerated electrical aging on chemical, dielectric, and physical properties to the oil performance. This research is conducted in order to assess the performance of natural ester during electric aging. Natural ester oil was made by using palm oil. Before it is used as liquid insulation, the viscosity has been reduced through transesterification processes. A triple needle-plane was immersed to the ester oil, and high voltage alternating current was injected to create an electrical arc for several minutes. The applied voltage was varied at 16 kV, 20 kV, and 24 kV (AC) as well as the arc duration, which varied at 0, 5, 10, and 15 minutes. Several measurements such as resistivity, relative permittivity, dielectric losses, breakdown voltage, and partial discharge have been conducted to observe the aging performance. The experiment results show that longer aging duration and higher applied voltage will fasten the degradation of the oil.","PeriodicalId":6677,"journal":{"name":"2019 2nd International Conference on High Voltage Engineering and Power Systems (ICHVEPS)","volume":"176 1","pages":"1-5"},"PeriodicalIF":0.0,"publicationDate":"2019-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"83783605","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}

To determine the failure that occurs in the transformer, the generation of certain gases within a transformer is an incredible indicator that has been proven so far. Because of the sensitivity and accuracy in measuring gases, this technique has become standard practice in normal maintenance activities at electric utility companies. This article presents the investigation of dissolved gas analysis (DGA) of four generator step-up (GSU) transformers at geothermal power plants in Indonesia. Each transformer insulating oil data were collected during yearly routine inspection and the DGA measurements at power plants for the duration of 6 years was obtained. DGA measurement result was analyzed and processed using the dissolved gas analysis method based on IEEE C57-104 and IEC 60599 standards. The interpretation of measurement data is conducted using four methods, that is key gas, gas ratio, Duval Triangle, and The Four Gases. Rogers Ratio, Doernenburg Ratio and Gas Ratio Combination are the gas ratio methods used in this study. The results of the diagnosis of generator step-up (GSU) transformers using DGA analysis showed that all four transformers were in different conditions for each analysis method. This paper highlights the importance of keeping track of DGA history and using several DGA interpretation methods to add confidence to the result.","PeriodicalId":6677,"journal":{"name":"2019 2nd International Conference on High Voltage Engineering and Power Systems (ICHVEPS)","volume":"20 1","pages":"1-6"},"PeriodicalIF":0.0,"publicationDate":"2019-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"77493892","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}

This flexibility will potentially cause changes in the operating pattern of coal-fired power plants, which operate at a minimum load. This pattern of operation will lead to increased use of coal, reduce the value of thermal efficiency, and possibly reduce equipment reliability. This paper presents an analysis of the impact of the flexibility of the coal-fired plant operation on its reliability. The solution that we propose in this paper is to integrate the coal-fired plant with Battery Energy Storage (BES). On scheme, the battery will be charged in a off-peak and will be discharged when a peak-load. We present several choices of BES in this paper, to find out more about this integration. in part 1 this will focus on how the impact of integration of coal power plants with battery energy storage in terms of heat rate levels, analysis is based on the effects of changes in heat rate levels of coal power plants during the use of BES and compared when not using BES.","PeriodicalId":6677,"journal":{"name":"2019 2nd International Conference on High Voltage Engineering and Power Systems (ICHVEPS)","volume":"1 1","pages":"1-6"},"PeriodicalIF":0.0,"publicationDate":"2019-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"84061702","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}

For this reason, it is necessary to apply a method of regulating electricity supply. Unit Commitment (UC) is daily scheduling of power generation units to achieve optimization goals while still meeting various operational, environmental, and technical constraints. With a significant increase of the operation of the RES intermittent power plant in the power system, the development of the UC method becomes more necessary, to maintain system stability and resilience, and minimum operating costs. Therefore, new optimization methods need to be developed to be applied to the UC scheme for microgrid electric power systems.This paper discusses alternative optimization methods to optimize UC solutions in microgrid power systems with intermittent RES plant. In this paper, a comparison of the strengths and weaknesses of each optimization technique is discussed, with the intent and purpose of finding the most appropriate optimization technique to utilize. The problem in the UC scheme has been studied by experts using numbers of methods. The combination of mathematical techniques and stochastic / meta-heuristic techniques is proven to provide better optimization solutions. This study is aimed at optimizing UC in electric power systems with intermittent RES power plants. In particular, the power system under study is a developing electricity system, for islands or remote areas. The proposed method is the enrichment of existing optimization techniques, with additional innovations in analytical methods to improve the performance of the UC schemes applied to the microgrid system.","PeriodicalId":6677,"journal":{"name":"2019 2nd International Conference on High Voltage Engineering and Power Systems (ICHVEPS)","volume":"14 1","pages":"344-349"},"PeriodicalIF":0.0,"publicationDate":"2019-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"72672869","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}
