{"title":"SCADA implementation in microhydro power plant control and monitoring systems of screw turbine type","authors":"","doi":"10.59018/032449","DOIUrl":"https://doi.org/10.59018/032449","url":null,"abstract":"Screw turbine-type micro-hydro power plants are still controlled manually by humans when there is a change in\u0000the electrical load on the generator output. If there is a change in the electrical load, the generator output voltage will\u0000change, thus affecting the rotation of the turbine being used. In this case, humans are needed to manually regulate the flow\u0000of water entering the turbine to maintain the stability of the generator output voltage by controlling the sluice gate. The\u0000water discharge entering the screw turbine will rotate the generator through a belt/gearbox pulley transmission, thus\u0000producing an electrical voltage at the generator output. To maintain the stability of the generator output voltage, it is\u0000necessary to control the water discharge entering the screw turbine. The expected goal of this research is to design a control\u0000system for a screw turbine type microhydro power plant to stabilize the generator output voltage and monitor the output of\u0000a screw turbine type generator using a SCADA (Supervisory Control, and Data Aquisition) system. The method used is the\u0000research and development method, namely the system design stage based on secondary data that has been collected, where\u0000the system design includes hardware design and software design, followed by making hardware such as control panels and\u0000devices. Software, which includes display design and leader diagrams and testing, is carried out by testing the system on\u0000software, hardware, and overall system testing. From the results of the discussion and analysis, the screw turbine type\u0000microhydro power plant control design system was created, a load control system consisting of 6 groups and sluice gate\u0000opening control that uses an ultrasonic sensor to determine the water level. With the results of controlling the sluice gate at\u0000a door opening of 30 mm, the generator voltage is 18.42 Volts DC, DC current is 0.0 Ampere at a load of 0 watts, when the\u0000load is 30 watts the generator voltage decreases by 18.40 volts, current is 1.37 Ampere. Through the on-line monitoring\u0000system, electrical parameters are obtained which are displayed on the SCADA system by looking in real-time at the history\u0000of DC voltage and DC current, DC power, and DC energy generated by the screw turbine-type DC generator. The voltage\u0000read is 18. 57 volts, current 1.37 Amperes, DC electrical power is 25.4 watts with a DC light load of 30 watts.","PeriodicalId":38652,"journal":{"name":"ARPN Journal of Engineering and Applied Sciences","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2024-05-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141127935","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}

IoT applications include healthcare, smart-cities, smart-cars, industries,\u0000quality of life, and several other fields. IoT typically consists of lightweight sensor devices that facilitate procedures such\u0000as automation, real-time trackable data collection, and data-driven decisions. However, securing IoT networks is an\u0000accessible research area for several reasons. The main security challenges are limited resources that are incapable of\u0000dealing with complex and advanced security tools; and lack of required data for training the security systems like Intrusion\u0000detection systems as a result of their heterogeneous nature. This research proposed a Few-shot learning IoT intrusion\u0000detection system model based on a Siamese network to overcome the above limitation. The model aims to classify and\u0000distinguish normal and attacked traffic. The experiment utilized an IoT dataset in different scenarios to analyze and\u0000validate the behavior with three categories with different numbers of data in each. The performance result achieves more\u0000than 99% accuracy and shows an efficient detection ability using only less than 1% of the dataset.","PeriodicalId":38652,"journal":{"name":"ARPN Journal of Engineering and Applied Sciences","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2024-05-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141127740","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}

As the design speed is proposed to be increased from 160 km/h to 250 km/h, the nose shape\u0000and nose length of the train head were modified into a sharper and longer nose. In this study, numerical simulation of\u0000computational fluid dynamics was used to investigate the aerodynamic phenomena and flow behavior around the modified\u0000train head and carbodies. The CFD simulation was used as the verification of the shape design and a tool for rapid design\u0000changes and optimization. The model configuration is three cars on a real scale by ignoring other parts like the train\u0000window and door, pantograph, and train connecting. A k-ε turbulence model was used in the simulation. From this\u0000investigation, it is found that the coefficient of drag on the model is calculated to be 0.34.

Subsurface information is very useful in addressing the subsidence problem more\u0000effectively and precisely.
