Every human activity always uses power electronic equipment such as motor drive power supply, charger, inverter, control system, etc. The principle of switching work on these equipment can cause harmonics so that they are considered as nonlinear loads. The large number of power electronic devices in the electric power system causes high harmonic distortion. THD and IHD are the measuring parameters for harmonics. High THD cannot be reduced by a shunt harmonic passive filter alone. Therefore, it is necessary to add additional devices such as a detuned reactor as additional equipment to increase the performance of the harmonic power filter. Combination of detuned reactor and shunt harmonic passive filter are placed on interline feeder bus. This interline method is done to save on adding harmonic filters to each feeder. Generally, each feeder is connected to a nonlinear load, so a harmonic filter is needed on each feeder. Several scenarios were made to compare the ability of the shunt harmonic passive filter (SHPF) when without a detuned reactor and when combined with it. All of these scenarios were carried out in the condition of the interline feeder of the electric power system. Each scenario show an increase in the ability of the SHPF after being combined with a detuned reactor. In the first scenario, the THD-I value is 18.16% in feeder number 1 and 15.86% in feeder number 2. THD-V value is 26.9% in feeder number 1 and 23.58% in feeder number 2. In the second scenario, the THD-I value is 9.57% in feeder number 1 and 10.96% in feeder number 2. THD-V value is 8.87% in feeder number 1 and 8.87% in feeder number 2. In the third scenario, the THD-I value is 3.95% in feeder number 1 and 4.53% in feeder number 2. THD-V value is 2.17% in feeder number 1 and 2.17% in feeder number 2.","PeriodicalId":156265,"journal":{"name":"2021 4th International Seminar on Research of Information Technology and Intelligent Systems (ISRITI)","volume":"38 3","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-12-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131491519","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 reuse of coal waste has been carried out in civil construction such as the cement industry. Coal ash is utilized in the manufacture of polymer insulating materials with the main ingredients of epoxy resin and silicone rubber. The feasibility of epoxy resin insulators, silicone rubber, and coal ash was tested by testing resistivity, dielectric strength, and tensile strength. The insulator material test was carried out according to ASTM standards and was carried out for 12 different types of samples. The addition of coal ash filler affects the dielectric strength of the test sample. The stability of the test value can be seen in sample S7, with the composition of the sample consisting of 30% resin A, 30% resin B, 20% silicone rubber, and 20% coal fly ash. The test results of the sample code S7 have a resistivity value of 42.793 $MOmega m$, a dielectric strength value of 154.133 kV/cm, a tensile stress value of 7.53 MPa, and a strain percentage of 16.75%.

The method used to solve the problem is Guided Local Search (GLS) and Simulated Annealing (SA) using Google OR-Tools which are proven to be efficient in solving heuristic problems. The results showed that the application of the GLS and SA methods showed different results, for the simulation of two and three fishing vessels the same distance optimization results were obtained, namely 290 miles and 355 miles, but for four fishing vessels the GLS method resulted in 464 miles while the SA method yields 439 miles, meaning that the more fishing vessels, the SA method has a better performance than the GLS method, for a case study of the distribution of fishing vessels in Maluku, the SA method is capable of 6% efficiency in distance while being able to save time and ship operational costs. The results of this study contribute to saving the company's operational costs and improving the quality of fish exports abroad.","PeriodicalId":156265,"journal":{"name":"2021 4th International Seminar on Research of Information Technology and Intelligent Systems (ISRITI)","volume":"26 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-12-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116333782","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}

These advantages make many countries prefer to use wind power plants as the main electricity generation compared to other renewable energies. However, it is also necessary to know how the wind power plant can respond to changes in load. The load always changes every hour according to the consumption of electricity by consumers. Therefore, this paper aims to analyze the stability of the wind power plant against changes in load. The type of wind power plant used in this paper is the Double Fed Induction Generator (DFIG). The parameter that is used as input to maintain the stability of the wind power plant is the pitch angle of the wind turbine. The pitch angles used are 0, 10, 20, and 30 degrees. Furthermore, to determine the stability response of the wind power plant parameter output, it is necessary to test it with changes in load. The change in load in question is the addition of a load when the wind power plant is operating. The wind power plant output parameters analyzed include current, active power, induction generator rotation speed, and voltage. The simulation results on the output voltage side, the greater the pitch angle, the greater the peak voltage increase, and vice versa. On the side of current, active power and rotor rotation speed, the smaller the pitch angle, the less wave disturbance fluctuations and the faster the DFIG reach its stable condition for the output parameters, and vice versa. From these relationships, it can be concluded that a pitch angle of ° degrees has a more stable output and can make DFIG more responsive to reach its normal condition when there is a disturbance that enters the electric power system.","PeriodicalId":156265,"journal":{"name":"2021 4th International Seminar on Research of Information Technology and Intelligent Systems (ISRITI)","volume":"169 4299 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-12-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115037738","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}
