Abstract

Power system stability is one of the important aspects in power system operation. Disturbances in the power system often occur which result in an increase in the level of oscillations that will have an impact on the stability of the power system. One of the models used in this research is the Single Machine Infinite Bus (SMIB) model, this model is able to understand and improve power system stability. This study aims to identify the influence and optimize the configuration of the constant value of the torque damping coefficient on the stability of the rotor angle and rotor angular velocity in the SMIB linear model. The analysis method uses transition analysis and stability analysis by providing variations in the value of the tested torque damping coefficient constant parameter. The simulation results show that when the value of the torque damping coefficient constant  which meets the design criteria for rotor angle changes characterized by rise time value of 0.17129 seconds, peak time of 0.37762 seconds, setlling time of 0.81285 seconds, peak value of 0.65566, and overshoot value of 15.224%.. Simulation results show that changing the constant value of the torque damping coefficient affects the stability of the rotor angle and rotor angular velocity in the SMIB linear model

Abstract

Sistem kelistrikan merupakan salah satu aspek penting dalam kehidupan sehari-hari karena hampir semua aktivitas manusia bergantung pada energi listrik. Ketidakstabilan frekuensi bisa terjadi akibat terhentinya operasi unit pembangkit besar atau jalur penghubung (tie line), serta ketidakseimbangan antara yang diproduksi dan daya yang diperlukan oleh beban. Agar tidak berpotensi merusak peralatan listrik, diperlukan analisis dan tanggapan untuk mengontrol penggunaan beban dengan menggunakan Load Frequency Control (LFC) yang dapat menjaga keseimbangan dan bertujuan untuk menjaga frekuensi serta daya aktif pada nilai nominalnya disaat terjadi perubahan beban. Penelitian ini berfokus untuk merancang pengendali  yang diterapkan pada sistem LFC menggunakan metode Particle Swarm Optimization (PSO) dan Zero/Pole Cancellation (ZPC) untuk mendapatkan konstanta pengendali yang sesuai. Uji sistem LFC dilakukan dengan perangkat lunak Matlab. Hasil penelitian menunjukkan bahwa pengendali optimal pada LFC tipe Reheat yang memenuhi kriteria perancangan..

Abstract

Effect of lightning parameters and grounding system impedance on transient overvoltage that occurs in 150 kV overhead transmission lines during lightning using ATP-EMTP modeling. The induced overvoltage that jumps across the insulator is calculated for further analysis. Various parameters that directly influence directly influence the backflashover phenomenon,, such as the effect of lightning strike amplitude, time of rise (front) and decay (tail) of lightning impulses, foot grounding system, and ground resistivity,, are discussed in more detail. Surge arresters are used in this study to overcome the overvoltage that can cause backflashover. The performance of the transmission system after using a surge arrester is investigated at the time of a lightning strike. The results indicate that the parameters of the advance time and the lightning current amplitude greatly affect the overvoltage magnitude voltage. Other parameters have little effect on the overvoltage in the transmission line.

Abstract

The Vertical Axis Wind Turbines are very suitable for use in areas with very low wind speeds. This research makes a prototype of the Savonius wind turbine to produce electrical energy as an energy source to 2 x 3.7 Volt dry battery. The Savonius turbine has four blades made of PVC. The controller circuit consists of a Boost Converter circuit and an astable multivibrator. At a speed of 2.7 m/s, the wind turbine starts to rotate and produces a no-load voltage of 0.3 V. At a speed of 3.7 m/s a voltage of 2 V is generated and can charge the battery. By using an LED (Light Emitting Diode) in the controller circuit, the charged battery can be a source of voltage in the controller circuit and the LED indicator light can be lit.

Abstract

This research discusses the performance of the hydraulic type Load Frequency Control (LFC) system in hydropower plants using a single controller configuration equipped with a governor against power input. The Load Frequency Control (LFC) system is used to stabilizer the power frequency during load changes by considering the influence of droop characteristics on the governor. Analysis is performed using MATLAB simulation to measure transient parameters such as rise time, peak time, steady state time, and maximum skip. The results show that the use of droop on the governor is more effective in reducing overshoot, improving system stability, but slowing down the response time. Conversely, the configuration without droop accelerates the system response but risks overshoot. Controllers with derivative components such as PD and PDF, are superior in achieving rise time. Whereas, controllers that have integral components such as PI, PID, and PIDF are better at controlling overshoot when using droop characteristics. In conclusion, the combination of droop characteristics with derivative components in the governor provides optimal performance in maintaining the frequency stability of the hydraulic type Load Frequency Control (LFC) system.
