Abstract

The load frequency control system aims to regulate the frequency in the electric power system at a normal value with a predetermined tolerance limit. In practice, the load frequency control system does not always operate optimally, therefore a controller is needed to be added to the load frequency control system. The controller designed is a variation of the combination of Proportional-Integral-Differential (PID) controllers with the standard model PIDTune method consisting of proportional (P) controller, proportional integral (PI) controller, proportional  differential (PD) controller, Proportional Integral Differential (PID) controller, Proportional Differential controller with first-order filter on differential section (PDF), and Proportional Integral Differential controller with first-order filter on differential section (PIDF). This study is aiming to carry out simulation and analysis in the frequency domain and then analyze the robustness of the reheat type power frequency control system and then design a PID controller for the reheat type power frequency control system in basic configuration, filter configuration, feedback configuration, feedforward configuration, and cascade configuration using PIDtune Model Standard on Matlab software. From the results of simulation and analysis, the controller that complies the design criteria and can make the reheat type of load frequency control system work optimally based on frequency domain analysis and robustness analysis is a proportional-integral (PI) controller in a feedback configuration with gain margin (Kg) equals to 38.11 dB, phase margin equals to 59.6°, infinity bandwidth, peak resonance value (Mr) equals to 1.19, maximum sensitivity peak value (MS) equals to 1.24, and complementary maximum sensitivity peak value (MT) equals to 1.17.

Abstract

This journal discusses about the analysis of frequency transition deviation of power frequency control system with Optimal control methods. The response of frequency transition deviation of power frequency control system is one of indicator in the performance of the power system during disturbances. These disturbances cause changes in the parameters value which result in power frequency control system will be disrupted and resulted system is not able to work normally after the disturbances. One of disturbance often occurs in power system is a sudden load changes. Sudden load changes cause of decreasing or increasing in the value of frequencies around the center of its operations. By using the optimal control method consists of Linear Quadratic Regulator (LQR) method and Linear Quadratic Regulator with weights function on the output (LQRy) are analyzed frequency transition deviation of power frequency control system type of Non-Reheat, Reheat and Hydraulic. The results obtained for the Linear Quadratic Regulator (LQR) method, the power frequency control system type of Non–Reheat has the smallest values of the transition parameter at the values of the transition parameter power frequency control system type of Reheat and Hydraulic. The values of the transition parameter power frequency control system type of Non-Reheat are 0.1266 seconds in time rise, 0.3451 seconds in settling time, 0.3451 seconds in peak time, 3.1972% in maximum overshoot and 0.0069 in peak value. For the Linear Quadratic Regulator method with weights function on the output (LQRy) power frequency control system type of Hydraulic has the smallest values of the transition parameter compared with the values of the transition parameter power frequency control system type of Non-Reheat and Reheat.

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 occupancy rate of the building has decreased due to the COVID-19 pandemic. Office buildings, hotels, apartments, and shopping centers experienced a decline in visitors. Meanwhile, some shops have stopped their business. The building management will continue to operate electrical equipment to support activities. The impact is that the load is unbalanced. This affects the load balance in the building. This condition will be detrimental and in the long term, will damage the transformer. The purpose of this study is to measure the level of electrical load balance in the Tang City Mall building. The measurement results on the existing 5-unit transformer show an unbalanced load between 0.63% to 4.76%. This measurement was carried out during rush hour conditions, namely at 17.30 WIB. Based on the calculation data, for a month, during a month you will experience a neutral current power loss of 2848kWh and a ground current power loss of 175 kWh. Instant measurements during mall opening and closing hours recorded a significant imbalance reaching 7.9% at trafo2. To avoid this, it is necessary to regroup, especially for single-phase loads. Meanwhile, building tenants' opening and closing hours must be simultaneous.

Abstract

Penelitian ini membahas tantangan dalam pembangkitan tenaga listrik terkait fluktuasi tegangan keluaran generator akibat perubahan beban. Sistem interkoneksi berskala besar menggunakan Automatic Voltage Regulator (AVR) untuk mengatasi fluktuasi tersebut, meningkatkan kehandalan sistem, dan memudahkan perancangan. Sebagian besar AVR yang ada mengadopsi algoritma Proporsional Integral Derivatif (PID), yang terus dikembangkan oleh peneliti. Penelitian dimulai dengan analisis performansi dinamik saat kondisi transient dan kondisi steady state sistem AVR tanpa pengendali, kemudian dilakukan perancangan pengendali Dua Derajat Kebebasan (2 DOF). Pengendali P, I, PI, PD, PID, PDF, dan PIDF, dikombinasikan dalam arsitektur 2 DOF. Konstanta pengendali ditentukan menggunakan PIDTune pada Matlab. Hasil simulasi menunjukkan performansi dinamik enam pengendali yang memenuhi kriteria perancangan, seperti P-PDF, PID-PID, PID-PIDF, PIDF-I, PIDF-PID, dan PIDF-PID. Kesimpulan dari penelitian ini adalah bahwa sistem AVR dengan pengendali arsitektur dua derajat kebebasan memberikan kinerja baik pada kombinasi pengendali tertentu. Kriteria perancangan pada kondisi transien dan kondisi steady state terpenuhi oleh keenam pengendali tersebut. Kesimpulan dari penelitian ini adalah bahwa sistem AVR dengan pengendali arsitektur dua derajat kebebasan memberikan kinerja baik pada kombinasi pengendali tertentu. Sedangkan untuk kondisi steady state nilai kesalahan keadaan mantap pada masukan undak bernilai nol karena tipe sistem AVR dengan keenam pengendali tersebut >1
