Short circuit fault analysis is needed to determine the amount of short circuit current flowing in a system. This study discusses the single-phase short-circuit current to the ground at the point where the disturbance occurs from the base of the network to the end of the Malewang feeder network. The purpose of this study was to determine the amount of short circuit fault current in the Electric Power Distribution System at PT PLN (Persero) UP3 South Makassar ULP Kalebajeng. This study used the ETAP program and manual calculations. The results of the study found that the contribution of the largest single-phase short-circuit fault current to the ground in the Malewang feeder occurred on Buses located at the base of the network close to the Substation, namely Bus 1 (Exim-Rec Kalaserena) of 0.311 kA, while thesmallest Buscontribution occurred on Buses located at the end of the network far from the Substation, namely Buses 14 (Bilonga) of 0.292 kA. From the results of the study, it can be concluded that the farther the interference bus is from the Substation, the greater the channel impedance. The greater the impedance, the smaller the short-circuit current.
为了确定系统中短路电流的大小,需要进行短路故障分析。本文讨论了从麻王馈线网底部到麻王馈线网末端发生扰动点处到地的单相短路电流。本研究的目的是确定PT PLN (Persero) UP3 South Makassar ULP Kalebajeng配电系统中的短路故障电流量。本研究采用ETAP程序和人工计算。研究结果发现,Malewang馈线单相短路故障电流对地贡献最大的母线位于靠近变电站的网络底部,即母线1 (Exim-Rec Kalaserena)为0.311 kA,而母线贡献最小的母线位于远离变电站的网络末端,即母线14 (Bilonga)为0.292 kA。从研究结果可以看出,干扰母线离变电站越远,通道阻抗越大。阻抗越大,短路电流越小。

Pico Hydro Power Plant (PLTPH) is one of the power plants that uses water as an energy source. Piko Hydro is included in the category of hydropower plants with small power because it does not need to use a water discharge that is too large to produce power. The tool developed in this study is a Pico Hydro Power Plant by Utilizing Flow Irrigation. The purpose of this research is to find out the results of the development of a Pico Hydro Power Plant, the electrical energy produced, and the community's response. The research method used is descriptive-quantitative with Research and Development (R&D) research and a prototype development model consisting of 4 steps, namely needs analysis, building prototypes, installing, and evaluating. The research data obtained by observation, questionnaires, and documentation. The results showed that the pico-hydro power plant works well, as indicated by the very good product validation value; the water wheel at the generator has a maximum power of 308 watts; and in development with the application of MPPT type charger control regulators, the results are able to stabilize the electrical energy produced and increase the power capability of the power plant with the help of a backup battery supply. For the results of the responses from the Kasambang Village community in Mamuju Regency, as many as 15 respondents obtained very decent results.

A maximum power point tracking (MPPT) for a proton exchange membrane fuel cell (PEMFC) using a combination of conventional finite control set model predictive control (FCS-MPC) and Technique for Order of Preference by Similarity to Ideal Solution (TOPSIS) is proposed in this paper. The key idea is to maximize the power generation from a PEMFC while minimizing the switching frequency of the power converter. The FCS-MPC technique is formulated to track the maximum power of PEMFC highly affected by ever-changing internal parameters. Meanwhile, the TOPSIS algorithm is applied to overcome the potential weaknesses of insulated-gate bipolar transistor (IGBT), which can only withstand a lower switching frequency. In this project, all simulations were run using MATLAB software to display the output power of the PEMFC system. As a result, the proposed predictive-TOPSIS-based MPPT algorithm can track the MPP for various PEMFC parameters within 0.019 s with an excellent accuracy up to 99.11%. The proposed MPPT technique has fast-tracking of the MPP locus, excellent accuracy, and robustness to environmental changes.
提出了一种结合传统有限控制集模型预测控制(FCS-MPC)和理想解相似偏好排序技术(TOPSIS)的质子交换膜燃料电池(PEMFC)最大功率点跟踪方法。其关键思想是最大化PEMFC的发电量,同时最小化功率转换器的开关频率。FCS-MPC技术用于跟踪受内部参数变化影响较大的PEMFC的最大功率。同时,利用TOPSIS算法克服了绝缘栅双极晶体管(IGBT)只能承受较低开关频率的潜在弱点。在本项目中,所有仿真都使用MATLAB软件运行,以显示PEMFC系统的输出功率。结果表明,基于topsis预测的MPPT算法可以在0.019 s内跟踪各种PEMFC参数的MPP,准确率高达99.11%。所提出的MPPT技术具有快速跟踪MPP位点、良好的准确性和对环境变化的鲁棒性。

The goal of the research is to find out how happy people are with Bima Kota's prepaid and postpaid energy services. Quantitative methods are used in this study. The data used is primary data, which comes from giving surveys to the people being studied. All the people who use energy in the Nitu Village in Kota Bima are included in this study. Cluster random sampling is used to get the sample data, and there are 100 people in the group. The results of the study show that 1) Tangibles, Reliability, Responsiveness, Assurance, and Empathy variables have an effect on people who use prepaid electricity services where people are satisfied with the services provided; 2) Tangibles, Reliability, Responsiveness, Assurance, and empathy variables have an effect on people who use postpaid electricity services where people are satisfied with the services provided; and 3) the dimensions of tangibles, reliability, responsiveness, confidence, and emphasis So that means there is a difference in how happy people are with prepaid electricity versus postpaid energy. As for the confidence dimension, it has a t count > t table or a prob value > alpha 0.05, which means that there is no significant difference between respondents who paid for their electricity in advance and those who paid for it later. The positive mean difference means that the average satisfaction of people who paid for their electricity in advance is better than that of people who paid for their electricity later.
这项研究的目的是了解人们对比马科塔预付和后付费能源服务的满意度。本研究采用定量方法。所使用的数据是原始数据,来自于对被研究对象的调查。所有在哥打比马的Nitu村使用能源的人都包括在本研究中。采用整群随机抽样的方法得到样本数据,组中有100人。研究结果表明:(1)有形、可靠性、响应性、保证性和共情变量对使用预付费电力服务的人有影响,人们对所提供的服务感到满意;2)有形、可靠性、响应性、保证性和共情变量对使用后付费电力服务的人有影响,当人们对所提供的服务感到满意时;3)有形的、可靠的、响应性的、自信的和强调的维度。所以这就意味着人们对预付电和后付费电的快乐程度是不同的。在置信维度上,它有一个t计数> t表或一个概率值> alpha 0.05,这意味着提前支付电费的受访者与后支付电费的受访者之间没有显著差异。正的平均差意味着提前支付电费的人的平均满意度比之后支付电费的人的平均满意度好。

Nano- and quantum-based low-power applications are where reversible logic really shines. By using digitally equivalent circuits with reversible logic gates, energy savings may be achieved. Reducing garbage output and ancilla inputs is a primary emphasis of this study, which aims to lower power consumption in reversible multiplexers. Multiplexers with switchable 2:1, 4:1, and 8:1 ratios may be built using the SJ gate and other simple reversible logic gates. The number of ancilla inputs has been cut in half from four to zero, and the amount of garbage output has been cut in half as well, from eight to three, making the 2:1 multiplexer an improvement over the prior design. New 4:1 multiplexer has 10' ancilla inputs, up from 2' in the previous designs. The proposed 4:1 multiplexer also cuts waste production in half from the current 5-to-6 bins per day. The 8:1 multiplexer has two ancilla inputs and nine trash outputs, while the current architecture only has one of each. The functionality of the VHDL and Xilinx 14.7-coded designs is validated by ISIM simulations.
基于纳米和量子的低功耗应用是可逆逻辑真正闪耀的地方。通过使用带有可逆逻辑门的数字等效电路,可以实现节能。减少垃圾输出和辅助输入是本研究的主要重点,旨在降低可逆多路复用器的功耗。可切换2:1,4:1和8:1比率的多路复用器可以使用SJ门和其他简单的可逆逻辑门来构建。辅助输入的数量减少了一半,从4个减少到0个,垃圾输出的数量也减少了一半,从8个减少到3个,使得2:1多路复用器比以前的设计有了改进。新的4:1多路复用器具有10'辅助输入,高于之前设计的2'。拟议的4:1多路复用器还将垃圾产生量从目前的每天5到6箱减少一半。8:1多路复用器有两个辅助输入和九个垃圾输出,而当前的体系结构只有一个。通过ISIM仿真验证了VHDL和Xilinx 14.7编码设计的功能。

The functionality of the VHDL and Xilinx 14.7-coded designs is validated by ISIM simulations.","PeriodicalId":37618,"journal":{"name":"Indonesian Journal of Electrical Engineering and Informatics","volume":"81 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-08-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135165484","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}
