Abstract

Induction Motor As Generator (IMAG) is an induction motor operated as a generator. IMAG widely applied in micro-hydro power plant (MHPP) with a power of less than 10kW. IMAG has many advantages such as: low price, easier maintenance, and widely available in the market. One of weakness IMAG is output voltage is affected by the load. In this research, we use induction motor 1 phase, 1 HP. In order to function as generator, it takes a capacitor 22 uF. IGC (Induction Generator Controller) is used to stabilize output voltage IMAG result of changes in load. IGC uses voltage censor to detect the change of consumer load. Voltage censor proceses linerarity level to the change of output voltage IMAG which equals to R2=0.995. The use of IGC causes the IMAG voltage is approximately 220.9 V to 224.7V and the IMAG frequency is 49.1 Hz to 50.5 Hz. Keywords: IGC, IMAG, microhydro

Abstract

MPPT (maximum power point tracking) merupakan cara untuk memaksimalkan daya keluaran pada pembangkit listrik tenaga bayu (PLTB). Sistem MPPT pada PLTB terdiri dari DC-DC converter dan metode kontrol. Pada penelitian ini, sistem MPPT menggunakan Four Switch Buck Boost (FSBB) converter, dimana converter ini memiliki polaritas tegangan yang sama antara input dan output, ripple tegangan rendah, dan efisiensi daya lebih besar dibandingkan dengan Buck Boost Converter. Metode kontrol yang digunakan adalah  Perturb and Observe (P&O)- ORB (Optimum Relations-Based) yang memiliki tingkat osilasi lebih rendah dan efisiensi lebih tinggi dibandingkan dengan metode P&O.Sistem MPPT disimulasikan menggunakan software PSIM untuk mengetahui performa P&O-ORB dan FSBB converter. Evaluasi kinerja  P&O-ORB dan FSBB diuji dalam kondisi kecepatan angin 5 m/s. Hasil simulasi menunjukkan FSBB memiliki tingkat kesalahan yang lebih kecil daripada Buck Boost yaitu 0,02%. Dan sistem MPPT dengan metode P&O-ORB memiliki tingkat efisiensi yang tinggi mencapai 98,01 %.

Abstract

Maximum power point tracking (MPPT) is a technique to maximize the power output of photovoltaic (PV). Therefore, to achieve higher PV efficiency, the development of MPPT control algorithm is necessary. Recently, it was revealed that fuzzy logic controller (FLC) is better than other control algorithms and is possible toe developed. This study fabricated and implemented MPPT based on the proposed a new FLC. Input Calculator (IC) via sensors reads current and voltage of PV and generates the comparison of voltage and current of PV, then IC output becomes fuzzy algorithm input. Fuzzy algorithm produces duty cycle that drives synchronous buck converter. The result showed that MPPT system with proposed FLC method has 99.1% efficiency while MPPT system with P&O method has 95.5% efficiency. From the obtained result, it can be concluded that the MPPT based on the proposed FLC can increase the overall efficiency of the system to 99.3%.

Abstract

Hasil salon PCB yang dilakukan secara manual menunjukkan tingkat prosentase keberhasilan yang masih rendah (50%), yaitu dari 50 potong PCB yang disablon, hanya 25 potong PCB yang dianggap memenuhi standard keberhasilan ( tidak terdapat track / jalur antar komponen yang putus), sedangkan yang lain tidak memenuhi standard. Oleh karena itu, untuk dalam program vucer DIKTI ini, kami membuat alat otomatisasi sablon PCB untuk meningkatkan hasil produksi dan efisiensi usaha PCB siap pakai. Alat ini mempunyai 2 bagian utama yaitu bagian kerangka mesin sablon PCB yang menggantikan kerangka sablon PCB manual yang tidak permanen, dan yang kedua bagian system control yang berfungsi menggerakkan rakel (arah horizontal, vertical dan kemiringan ) secara otomatis. Dengan mengganti alat sablon PCB manual menjadi alat PCB otomatis dan dengan bimbingan, monitoring dari tim pelaksana, BELT dapat meningkatkan prosentase pensablonan dari 50% menjadi 83,3%.   Keyword : Program vucer, Sablon PCB Otomatis, Efisiensi Usaha.

Abstract

A higher electric power generation was needed along with the increasing human populations and the development of technology. The use of renewable energy could act as an alternative way to solve the growing load demand. However, renewable energy faced an obstacle because electrical power could not be continuously built to fulfil the load’s requirement.  Transferring energy could help balance the energy and the system. Thus, the Energy Management System was needed to meet the stable and continuous load’s requirement. In this thesis, the Energy Management System was chosen as the scheduling system for DC’s grid with the PV as the renewable energy. The PV was connected on-grid to the utility network; thus, the power could be exchanged with the utility grid. A battery was used as the extra reserve energy supply when the highest loads happened. Based on the results, filling schedule of power was conducted by importing power when the load power requirement was less than 25 kW and no energy was generated from the PV. Furthermore, when there was power generation in the PV, the EMS would schedule the power at the incoming PV to meet the load when the generated power was higher than the required. The use of batteries as a backup energy source was utilised when the load requirement was greater than 25 kW because the battery here served to meet the power requirements when peak loads occur. The results also followed the EMS scheme, where the load’s demand was fulfilled entirely with precise scheduling. Finally, the strain on the DC bus was successfully maintained at 48 VDC to avoid energy decreasing.

Abstract

This study discusses the power control strategy in a standalone photovoltaic-battery hybrid system. The life-time of the battery will be shorter if the battery is often charged with high current and exceeds its State-of-Charge (SoC). Therefore, a control method is needed to control the power flow on the DC bus and the charging current as well as the SoC of the battery so that the battery has a long life-time. The proposed system uses two dc-dc converters to connect photovoltaic (PV) and lead-acid batteries to the load. The unidirectional DC-DC converter is used as the interface between the PV and the DC bus, the bidirectional DC-DC converter is used as the interface between the battery and the DC bus. The control strategy plays a role in controlling the power flow between the converter and the load to maintain the balance of power in the system and controlling the battery to support PV when the available PV power is not enough to meet the load. The multi-loop control strategy is proposed in this study, one of the loops is used to maintain the SoC of the battery in order to control the PV output power to avoid over-charging. Another loop is used to ensure the balance of the system's power when the battery is charging at its maximum charge current. The proposed control system is implemented without requiring any conditions for the control to operate. The simulation results show that the proposed multi-loop control can control the power flow in the system while maintaining the maximum charging current and battery SoC limits.

Abstract

Due to its lower cost and quicker response in compassion with governor, electronic load control (ELC) has been widely used to replace governor in microhydro power plant. It has lower price and quicker response than governor. The synchronous generator used in microhydro power plant produces stable voltage, because it has been controlled by an AVR (automatic voltage regulator. If consumer loads changes, the frequency not the voltage of the electrical wave will change. Therefore, ELC is used to stabilize the electrical wave frequency and detect the change of consumer load to be transferred to ballast load. This ELC uses frequency censor to detect the change of consumer load. Frequency censor proceeses linearity level to the change of voltage which equals to R2= 0.97. The use of ELC causes the generator voltage is approximately 220,3V to 224,4V with percentage of voltage unbalance 0,56% and the geneator frequency is 49,5Hz to 50,1Hz with percentage of frequency unbalance 0,41%.
