Transmission lines are an important part of a power system. Transmission lines have high power transmission capacity and they are prone to faults of larger magnitudes. Various faults occur in transmission lines. Therefore, protection relays are necessary to protect transmission lines. The purpose of protection system is to interrupt the faulty section from the healthy section because the fault currents may damage the electrical equipments. One of the protection relays is distance relay and it is mainly used in transmission line. Sometimes these relay are used for backup protection. Distance relays for determining the impedance need the voltage and current. Transmission lines are typically protected by distance protection relay. Distance relays are considered of high speed class and can provide transmission lines. Nowadays, numerical distance relays have been used instead of using electromechanical and static distance relays. The proposed model was verified under different tests such as single line to ground (L-G) fault, double line to ground (L-L-G) fault, line to line (L-L) fault and three phase (L-L-L) fault. SimPower System was used for modelling and simulation of distance relay, transmission lines and faults. The simulation results were obtained from MATLAB software shows the feasibility of analysis of transmission line protection with mho type distance relay for single line to ground fault, double line to ground fault, line to line fault and three phase fault at different location of transmission lines. The difficulties understanding on operation of distance relay can be cleared by using MATLAB/SIMULINK software.

Nowadays, power quality is one of the major problems in electric power distribution system. The poor power quality at distribution level can affect the operation and performance of sensitive and critical loads. In the distribution systems, poor power quality results in various problems such as higher power losses, harmonics, sag and swells in the voltage, and poor power factor., etc. Unified Power Quality Conditioner (UPQC) is the only versatile device which can mitigate several power quality problems related with distribution system. A UPQC that combines the operations of a Distribution Static Compensator (D-STATCOM) and Dynamic Voltage Restorer (DVR) together with the shunt and series active control devices. UPQC can solve the problems related to the voltage/current harmonics, voltage sag/swell and unbalance in distribution system. To evaluate the performance improvement in the system, a model of UPQC is developed in MATLAB/SIMULINK with a typical distribution network. In this research, UPQC is applied for power quality enhancement of Myaungtagar industrial distribution substation, Myanmar. Enhancements in power quality by UPQC are evaluated under maximum load condition.Keywords—Power Quality, UPQC, Series Controller, Shunt controller, Harmonics

The lack of a disaster information system nowadays has made it difficult to find out information in the disaster area. Making information systems in disaster areas is important to solve the problem of uneven distribution of aid provided at each barrack. Because the conditions of each barrack are different, a system is needed to determine the priority for selecting disaster. To be able to determine the recommendations for the selection of disaster barracks, this study uses the Fuzzy Simple Additive Weighting (Fuzzy SAW) method, uses fuzzy method to determine the input basis value to SAW [3]. With the implementation of the Fuzzy SAW method, the results of this study can provide recommendations for Badan Penangguangan Bencan Daerah (BPBD) of Malang to determine the priority of disaster barracks that can take precedence.

Damage to the electrical components will inevitably occur, it could be caused by several factors that influence it starting from inside and outside the system. 3 phase induction motor is the most commonly used in the industry, but often also has problems such as over current and over heat on the motor. The disturbance if left unchecked can cause fatal damage to the motor. therefore, a relay safety system has been made which utilizes a microcontroller controller to protect the 3 phase induction motors. This safety relay is designed differently than conventional safety relays used by industry in general, this safety relay is designed based on the microcontroller control and is accompanied by setting and resset facilities respectively to display on the LCD via Push Botton buttons. As such, 3 phase induction motors are protected from severe damage caused by interference with the mesh source. It is expected that by making this safety relay can reduce the value of damage to the 3 phase induction motor.

The importance of socialization about alternative energy that can be used for daily needs, for example from the simplest such as lighting at home, although not permanent but is very useful in the event of a sudden power outage. The high price of electricity makes small communities have to think twice as much to regulate daily expenditure needs so as to encourage to find alternative energy that can produce electricity that is environmentally friendly. Seeing the large number of detergent products in Indonesia, it inspires to process the waste from laundry clothes or other objects and even the detergent water itself, because so far the used laundry waste is thrown away so that it can pollute the environment. The purpose of this study is to reduce the effect of environmental pollution due to used laundry waste which is used as an alternative energy source to turn on lighting lamps at home or even on the road. The method used in this research is a chemical or electrolysis reaction involving zinc and carbon as well as the content in detergent washing water. From several experiments conducted for 3 detergents with several parameters, namely the amount of mass and water volume of 120 ml. From the experiment the voltage is 1 volt with a current of 2 mA for detergent Rinso, for DAIA detergent the voltage is 0.7 and current is 0.56 mA, and the experiments tested on SOKLIN produce a voltage of 0.8 volt and a current of 1 mA. Whereas the testing which was carried out randomly with a volume of 1200 ml water produced a voltage of 0.547 v with a large current of 0.006 mA. This proves that detergent waste can be utilized as a renewable energy although it still requires further research but this can ease the burden on the community to pay for electricity from PLN and in the subsequent development independent power plants are built in each house so that the community can save on electricity.

With the rapid development of unmanned surface vehicle (USV), the development of hybrid electric vehicles on USV is a technology that has a very important role to overcome the problem of how long the vehicle can be used. In hybrid electric vehicles (HEV), the main components consist of generators, electric motors, and batteries. Modeling component is intended to design models that fit on unmanned surface vehicle and represent the state of USV with hybrid drivetrain. This paper focuses on modeling USV with hybrid drivetrain. This vehicle uses a series configuration so that the generator act as a power generating system. The power system on USV was chosen using hybrid sources of DC generator and lithium-ion battery pack. The optimal size of DC generator and battery pack are very important to ensure that USV can work for a long period of time. This paper describes the simple characteristics of a DC generator with a PI controller and gain-scheduling PI controller which is accurate in generating 380V output voltage according to the initial plan to be built. We also described the model of permanent magnet dc motor as a driver in USV and described simulation about 200Ah 36V lithium-ion batteries. The development of this model will be represented in MATLAB/Simulink.

Inrush current is a transient phenomenon that occurs when a transformer is first energized to a voltage source at no-load conditions. It causes a very high inrush current. Inrush currents can adversely affect the electric power system and can cause improper work of a relay protection errors. The purpose of this study is to determine the amount of inrush current and minimize the amount of inrush current by using the pre-fluxing method.In this study, a test was carried out using a 3-kVA core type 3 phase transformer. This test is done by giving DC flux before the transformer is connected to the voltage source, then the three transformer phases are energized simultaneously at a certain voltage angle so that the inrush current may could be minimized. The test results show that the transformer that is given a DC flux always has a relatively small inrush current. In this test the inrush current is reduced to a minimum value at an ignition angle of 90 degrees with an inrush current value of 0.74 A in phase R, 3.41 A in phase S, and 3.80 A in phase T.
涌流是一种暂态现象，当变压器在空载条件下首次通电到电压源时发生。它会产生非常高的涌流。涌流会对电力系统产生不利的影响，并可能导致继电保护工作错误。本研究的目的是利用预磁通法确定浪涌电流的大小，并使浪涌电流的大小最小。在本研究中，使用3kva铁芯型三相变压器进行了测试。这个测试是在变压器连接到电压源之前给出直流磁通，然后以一定的电压角同时给变压器三相通电，这样浪涌电流就可以最小化。试验结果表明，给定直流磁通的变压器总是具有相对较小的浪涌电流。在本试验中，在点火角为90度时，浪涌电流减小到最小值，R相的浪涌电流值为0.74 a, S相的浪涌电流值为3.41 a, T相的浪涌电流值为3.80 a。

It causes a very high inrush current. Inrush currents can adversely affect the electric power system and can cause improper work of a relay protection errors. The purpose of this study is to determine the amount of inrush current and minimize the amount of inrush current by using the pre-fluxing method.In this study, a test was carried out using a 3-kVA core type 3 phase transformer. This test is done by giving DC flux before the transformer is connected to the voltage source, then the three transformer phases are energized simultaneously at a certain voltage angle so that the inrush current may could be minimized. The test results show that the transformer that is given a DC flux always has a relatively small inrush current. In this test the inrush current is reduced to a minimum value at an ignition angle of 90 degrees with an inrush current value of 0.74 A in phase R, 3.41 A in phase S, and 3.80 A in phase T.","PeriodicalId":32708,"journal":{"name":"JAREE Journal on Advanced Research in Electrical Engineering","volume":"72 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2019-10-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"86264456","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}
