Abstract

Conventional DC motors often experience problems that require regular maintenance. The use of conventional DC motors can be replaced with Brushless DC (BLDC) motors. This BLDC motor has good efficiency and durability. Increasing the ability of BLDC motors can be done by speed regulation using the Proportional-Integral-Derivative (PID) method combined with Firefly Algorithm. Testing this method uses matlab 2014a. The firefly algorithm can obtain parameter values of Kp, Ki, and Kd which are then used as PID input. Because of inaccuracies in determining the value of a constant in PID and can cause the length of time to reach the desired speed. BLDC motor speed regulation with the PID method combined with firefly algorithm can make the BLDC motor reach synchronous faster

Abstract

The disturbance of transformers often occurs at the field is named partial discharge. It refers to the spark release in the isolation of internal cavity or surface caused by the potential difference in the transformer isolation. As a result, the quality degradation of isolation material happens. To test it, the researcher employed Dissolved Gas Analysis by Roger's Ratio and Duval Triangle methods. The results demonstrated that transformer GT 10 reached the highest temperature of 417,229⁰C and produced overheating as indicated by paper carbonation and carbon particle formation in the oil (thermal fault 3000C–7000C). Meanwhile, the GT 20 transformer achieved the highest temperature of 169.2307⁰C and the color of paper isolation change to brown (at <300°C). Both transformers were detected getting the failure of partial discharge as the temperatures were more than 150⁰C; in which several gases were formed, including hydrogen and methane gases at around 150⁰C, ethane gas at approximately 250⁰C, ethylene gas at about 350⁰C, and acetylene gas at around 700⁰C. Accordingly, the higher the temperature, the lower the dielectric capacity, where it should function for separating the electrical conductors.

Abstract

Aspek kestabilan frekuensi yang ada pada PLTA sengguruh bergantung pada turbin dan generator induksi yang ada didalamnya, seringkali tidak dapat bekerja dengan baik ketika kondisi masuk debit penuh, dan yang akan terjadi ketika frekuensi tidak stabil adalah generator akan beroperasi diluar kurva kapabilitasnya sehingga tidak akan bisa dilakukan interkoneksi dengan sistem karena syarat interkoneksi adalah frekuensi yang sama. Kontrol PID menjadi salah satu pilihan yang digunakan untuk memperbaiki frekuensi saat masuk debit penuh dan masuk beban penuh secara langsung. Tuning PID saat ini yang paling popular adalah Ziegler-Nichols (dalam penelitian ini didapatkan nilai Kp adalah 1,9 dan Ki adalah 0,06), namun yang akan digunakan dalam penelitian ini adalah Tuning berbasis PSO (dengan Kp 1.6331 dan Ki adalah 0,8810). Dari hasil simulasi didapatkan perbandingan antara tuning PSO dengan tuning Ziegler Nichols, adalah frekuensi overshoot PSO lebih tinggi sekitar 0,04%, percepatan waktu steady state PSO sebesar 42,032 s atau lebih cepat 46,03%. Waktu untuk mencapai steady state pada tegangan dari PSO lebih cepat 7,35% dan overshoot tegangan sediki lebih rendah dari Ziegler Nichols sebesar 0,47%. Waktu untuk mencapai steady state pada daya dari PSO lebih cepat dari Ziegler Nichols sebesar 5,71%.Kata Kunci : Kestabilan Frekuensi, PID controller, Ziegler-Nichols, Particle Swarm Optimization (PSO).

Abstract

A power flow analysis is a study that aims to obtain information on the electrical network system. production development of PT. Trias Sentosa, Tbk. very fast. Especially in the production section, there are always additions and updates to machines, so the burden that is borne will also increase. As a result, in carrying out their duties, the machines will always experience malfunctions or errors. To minimize these conditions, it is necessary to have a power flow analysis in order to review the condition of the electric power system. The benefit of this power flow analysis is that it can determine the condition of an unbalanced load. In research that uses manual calculations and calculations on this ETAP, using the current equation method to get the results of the power flow analysis. case studies of monitored power flow analysis in the form of voltage profiles, output power, input power, transformer loading, power loss values, voltage drop values, and load imbalance values

Abstract

This Pasar Surya Surabaya Regional Company is an official market management under the Surabaya City government. In 2020, companies in the solar market area changed building assets into several open space places to become infrastructure facilities for economic improvement. The current power requirement is 197Kva and will be increased to 275 Kva. The planning of off-grid PV mini-grid for the Pasar Surya Regional Company, which was previously connected to PLN for 197 KVA, requires 1692 PV 380 WP for installation in an effective area of ​​3296.5 m2 and is divided into 3 PV arrays. with each array consisting of 19 series and 30 parallel PV arrays. Batteries with a capacity of 24V 300 Ah are needed as many as 342 pieces which are divided into 3 parts, with each part consisting of 19 series arrangement and 6 parallel battery arrangement. SCC (Solar Charge Controller) 240 KW requires as many as 3 pieces. Inverter 200 KW requires as much as 1 piece. In one year the energy that can be produced by PLTS is 950130 kWh, with a performance ratio showing the efficiency of PLTS at PD Pasar Surya which is 66.5%. The total cost of installing PLTS is around Rp. 16,204,258,086,- not including construction and installation costs. Meanwhile, to return the capital to be equivalent to the use of PLN, it takes an operating time of around 16 years
