Abstract

Generally study of power-flow used the system presentation with the well-balan-ced load. Presentation like this enabled to solve power-flow used single phase presen-tation. Well-balanced load distribution system is very rare. Condition of unbalance load on distribution system needed the special power flow program which can solve three phase power system.This research made and tested three phase power-flow program with adaptive compensation-based method using the application program MATLAB 6.5.1. This method emphasized to solve power-flow of radial system with balance or unbalance load and dis-persed generation. Result of research showed for the validation of program using standard data 15 bus that is getting of converged to the specified tolerance value (1x10-8) for the various lo-ading condition. Unbalance load caused the power mismatch at same iteration tend to in-crease in linear. Addition load factor at one of phase (phase A) caused power mismatch at same iteration tend to increase by exponential. Dispersed generation gives decrease voltage drop in most of all buses and decrease power loss until 73,64 %. Unbalance load on Airlangga feeder caused increase system loss until 38,09%. The biggest contributions of loss cause by longest branch feeder on bus 4 to 6 equal to 39,68 %. Biggest voltages drop at the end of feeder with average degradation until 0Ð0,0130 pu for balance and un-balance load.

Abstract

SMAN 3 Mataram has a vision of forming human resources who are honest, trustworthy, and smart. One of the missions is to improve the ability in science, technology and skills. During the COVID-19 pandemic, healthy and clean living behavior is required according to the protocol by keeping a distance and avoiding crowds. To encourage skill and creative students, the PKM Team carries out Arduino training to measure non-contact body temperature. Arduino training modules are made easy to disassemble and can be monitored by Android phones via Bluetooth, with the MIT APP Inventor 2 program interface. The MLX90614 sensor can be used as a body temperature measurement via wireless during the Covid-19 pandemic. The training was carried out by means of presentations on the basic principles of Arduino and the introduction of analog sensors to measure body temperature. In order to be effective and efficient, the presentation of hardware circuits is directly practiced and supervised by electrical students. Competent lecturers provide training on making android programs, case studies of body temperature sensors. This PKM activity was attended by 23 students who were divided into 4 groups to match the number of modules. Based on the results of the evaluation of the pretest and posttest, there was an increase in knowledge of 34.5% from the pretest average of 51.2 to the posttest average of 78.2. A total of 13 students (56.6%) had additional motivation to find out more about the Arduino application.

Abstract

Intelligent control included ANFIS and type-2 fuzzy (T2FLS) controllers grown-up rapidly and these controllers are applied successfully in power system control. Meanwhile, small signal stability problem appear in a large-scale power system (LSPS) due to load fluctuation. If this problem persists, and can not be solved, it will develop blackout on the LSPS. How to improve the LSPS stability due to load fluctuation is done in this research by coordinating of PSS based on ANFIS and T2FLS. The ANFIS parameters are obtained automatically by training process. Meanwhile, the T2FLS parameters are determined based on the knowledge that obtained from the ANFIS parameters. Input membership function (MF) of the ANFIS is 5 Gaussian MFs. On the other hand, input MF of the T2FLS is 3 Gaussian MFs. Results show that the T2FLS-PSS is able to maintain the stability by decreasing peak overshoot for rotor speed and angle. The T2FLS-PSS makes the settling time is shorter for rotor speed and angle on local mode oscillation as well as on inter-area oscillation than conventional/ ANFIS-PSS. Also, the T2FLS-PSS gives better performance than the other PSS when tested on single disturbance and multiple disturbances.

Abstract

Current control scheme is commonly used in high voltage direct current (HVDC) to transmit power delivery. This scheme is done by adjusting trigger angle to regulate direct current (DC) in thyristor devices. The adaptive neuro-fuzzy inference system (ANFIS) control is widely applied for start and fault operation. But, solution for transient response of DC current in HVDC system is not clearly studied before. In this paper, supplementary control (SC) based on ANFIS is proposed to improve the transient response of the current. The SC control is designed by learning-processes and SC parameters are obtained by data-training automatically. For current reference at 1.05 pu and up-ramp at 20 pu/s, maximum overshoot is achieved at 5.12% and 7.72% for the SC and proportional integral controller (PIC), respectively. When the up-ramp is increased to 28 pu/s, the maximum overshoot is achieved at 10.01% for the SC. While, the peak overshoot for the PIC is 14.28%.

Abstract

Chaos and voltage collapse occurred in critical power systems due to disturbing of energy. PID-SVC layered reccurrent neural network-based (LRN-based PID-SVC) was proposed to solve these problems. The PID is used to control chaos and voltage collapse. Meanwhile, an SVC LRN-based is used to maintan the load voltage. By using the proposed controller, chaos and voltage collapse are able to suppress and maintain the load voltage around the setting value. When the maximum load isforced to load bus, the reactive power supplied by SVC, SVC additional voltage and load voltage are at the values of j0.1127, 4.0095´10-3 and 0.980010 pu, respectively. Furthemore, the proposed controller gives better response than PI-SVC controller.

Abstract

Modern power system are very vurnerable to against load fluctuation during their operation. Load fluctuation identified as small disturbance is important to test dynamic (small signal) stability. This research is focused on improvement of multimachine dynamic stability by using ANFIS-based power system stabilizer (proposed PSS). ANFIS method is proposed because the ANFIS computation is more efective than Mamdani fuzzy computation. Simulation results show that the proposed PSS is able to maintain the dynamic stability by decreasing peak overshoot (Po) to the value -3,37´10-5 pu/pu and accelerating settling time (St) to the time 4.01 s for rotor speed deviation Machine-2. Also, the Po is decreased to the value -3,37´10-5 pu/pu and the St is accelerated to the time 3.98 s for rotor speed deviation Machine-3.

Abstract

Power generating units should be built closed to load centers according to electric power company regulation. These units are generally small in capacity, so that makes power transfer among inter- and outer-areas is easier to be done. This study aims to improve dynamic stability of a Micro Hydro Power Plant (MHPP) on perspective of 5% load increased in Diesel Power Plant (DPP). The DPP is equipped by an ANFIS-based Power System Stabilizer (PSS) in this scheme. Two inputs with Gauss2mf membership function (MF) type and 5-number of the each MF are used to implement the ANFIS model. Simulation results show that overshoot of MHPP power angle deviation is reduced to the values of 0.023, 0.0138 and 0.0132°, for the DPP without PSS, conventional and ANFIS PSS, respectively.  Also, reduction in setting time is achieved at times >6, 4.051 and 3.553 s. It is shown that the ANFIS PSS is more effective to enhance the dynamic stability compared to other PSS

Abstract

Teknologi fuzzy tipe 2 (FT2) berkembang sangat pesat dan memasuki bidang stabilitas sistem tenaga listrik. Pembangkit listrik tenaga mikro hidro (PLTMH) dan diesel (PLTD) riskan terhadap gangguan perubahan beban. Studi stabilitas penting dikerjakan untuk memastikan bahwa operasi PLTMH-PLTD tetap stabil ketika dan setelah beban berubah. Maka power system stabilizer (PSS) berbasis FT2 diusulkan untuk perbaikan stabilitas sistem tersebut. FT2PSS didesain dengan input kecepatan rotor dan derivatifnya. Outputnya adalah sinyal stabilitas yang diumpankan pada sistem eksitasi. Hasilnya, FT2PSS mampu mereduksi overshoot -0,035 deg. Sedangkan overshoot untuk CPSS adalah -0,051 deg. FT2PSS juga dapat mempersingkat settling time dan mempercepat steady state. Stabilitas PLTMH-PLTD yang dilengkapi dengan FT2PSS diperbaiki secara significan.
