Abstract

The design of the inverter control system aims to regulate active power and reactive power flows from the batteries through the three-phase inverter. Reference power generated manually to compensate the active and reactive power required by microgrid. Modelling done by the transformation clarke-park to design close loop system with PI (Proportional Integral) control so that the current flows in the inverter is maintained at the reference value. PLL (Phase Locked Loop) is used to synchronize inverter and grid. The simulation result shows that the system can work very well and the voltage or frequency of microgrid maintained under normal conditions.

Abstract

Hydro power plant is kind of electric power generation which utilize energy from water fall to produce electricity. One of its operational problem is limited water supply and available water which can be stored in reservoir. This limitation will affect the electrical energy can be generated by the hydro power plant. This paper present a methodology of medium term optimization of hydro power plant operation to maximize its energy production with considering water availability in reservoir as operational constraint. Operation optimization problem is formulated in Linear Programming model and then solved using Tomlab optimization software. Simulations using water flow data of Ketenger Hydro Power Plant on June 2013 show that this method can be used to solve hydro power plant operation optimization problem well. Based on the simulation results with a period of 720 hours (1 month) the total electrical energy that can be generated is equal to 2990.8 MWh. This value is 69,6 MWh (or 2,3%) greater when compared to the real condition of electrical power generated in June with ammount of 2921,2 MWh.

Abstract

Tujuan utama dari pembebanan ekonomis adalah meminimalkan jumlah biaya operasi setiap unit generator dengan mempehatikan batasan persamaan dan ketidaksamaan sistem. Saat ini dengan meningkatnya perhatian pada polusi lingkungan yang diakibatkan proses pembakaran bahan bakar fossil pada pembangkit termal, emisi polutan tersebut juga menjadi kriteria yang harus diminimalkan. Pembebanan ekonomis dengan mengendalikan emisi (economic emission dispatch) yang adalah permasalahan multiobyektif mendapat peranan tersendiri dalam operasi ekonomis sistem tenaga listrik dan banyak mendapatkan perhatian para peneliti. Dalam penelitian ini metode faktor harga penalti diaplikasikan untuk merubah permasalahan multiobyektif kedalam bentuk persamaan obyektif tunggal. Penelitian ini memberikan sebuah pendekatan yang sederhana dan efektif untuk mencari solusi optimal permasalahan tersebut dengan menggunakan algoritma Evolusi Diferensial. Simulasi dilakukan pada sistem dengan skala unit kecil 3-unit dan 6-unit serta pada sistem dengan skala unit besar yaitu 40-unit pembangkit dengan program MATLAB. Hasil perhitungan memperlihatkan bahwa algoritma ini memberikan hasil yang lebih optimal dan efesien pada permasalahan kombinasi pembebanan optimal ekonomis dan emisi pada sistem dengan skala unit kecil dan memberikan keseimbangan antara biaya bahan bakar dan jumlah emisi jika diterapkan pada sistem dengan skala unit besar.

Abstract

Radiation monitor system or widely known as surveymeter has been widely used to monitor the rate of radiation exposure by utilizing detector to detect radiation pulses generated by radioactive substances. This study focused on testing the radiation monitor module used in the system of monitoring the transport of radioactive substances. The stability of the module was tested by chi square test with a standard source of Cs-137 performed a total of 20 data measurement range test instrument is done by providing a standard pulse from the pulse generator with a frequency of 1 to 327 kHz frequency as a substitute source of radiation and cps conversion factor to mR / h is done by comparing the results of measurements with standard tools. From the results of this study, the value of testing the stability of the background count 15.54 and the count value with 19.76 sources and within the range of 11,7 ≤ c2≤ 27,2 So this system is acceptable and has been functioning properly. While the conversion factor cps to mR / hr is 0.058 mR / jam.cps so the range radiation module is 0.058 mR / hr up to 18.98960 R / hour.
