Research has been carried out to regulate / control the rotation of the turbine for this type of micro hydro power plant (PLTMH). This research was carried out during the dry season where water discharge greatly affects turbine rotation. This tool utilizes an optocoupler sensor, servo motor and 2x16 LCD. This system works based on the turbine rotation speed that is read on the sensor then controls the slope of the water fall using a DC motor. If thewater speed is low, the servo motor will turn CW up to a maximum slope of 75 degrees to produce maximum rotation and maximum power. This research does not focus on the magnitude of the resulting current source and the amount of water discharge

Hydro Power Plants

The dependence of power plants on energy sources such as diesel, natural gas and coal is almost 75%, encouraging the development of renewable energy in an effort to meet the electricity supply. One of them is the micro hydro power plant by utilizing the potential of existing water. The working principle of PLTMH is to change the potential energy of water into electrical energy. In this final project has been designed modeling of micro hydro power plant by using screw turbine (Archimedes Screw). The turbine used resembles a drill bit, with a diameter of a turbine of 26 cm, a screw width of 10 cm, and an amount of 10 pieces of blade. Measurements made on the modeling of micro hydro power plants include: water discharge, turbine rotation, generator rotation, voltage, current, torque and generator output power and efficiency. The parameters are measured by changing the water fall on the turbine from the position of the turbine head angle 00, 100, 150, 200, 250, 300, 350, 400, 450, 500, 550, 600, 700, 800  and 900 . The result of measurement that has been done on the parameters of micro hydro power plant modeling, obtained the highest measurement result at the corner of turbine head 400. The output power generated is 10.92 watts, torque is 0.60 Nm and efficiency of 14%. The results obtained are still low because the turbine rotation is less able to rotate the generator, where the generator torque is greater than the torque in the turbine. This is influenced by the small water discharges in the modeling of this micro hydro power plant.

Issues of the contraflows formation in the Votkinsk Reservoir (the middle one in the sequence of the Kama reservoirs) have been studied. The water discharge regime through the Kama Hydro Power Plant determines the contraflow occurrence. The importance of the contraflow issues is caused by the risk of contaminated waters input to water intakes located upstream in respect of the waste water outlets. One of the major industrial agglomeration, namely the Perm-Krasnokamsk cluster with numerous water intakes and waste water discharge points, is located in the upstream part of the Votkinsk Reservoir with is the downstream reach of the Kama Reservoir. On the basis of assessment of the contraflows scale and the consequences for water users the water/economic and environmental limitations are set for the power plant operation regime including sanitary discharge volumes. The contraflows have been simulated as a result of digital solution of the Saint-Venant equation in 1D-definintion with input of the first type boundary conditions directly in the vicinity of the Votkinsk Power Station dam. We have assessed the reservoir morphometry role in the contraflows formation. Outputs of the comparative experiments performed at different schematic models of the Votkinsk Reservoir have shown that reflection of the level lowering straight wave from the Votkinsk Power Station dam is the determining factor of the contraflows formation rather than peculiarities of the morphometry. When decreasing the period of water discharge to the downstream reach the zone of contraflows formation is displacing towards the Votkins Power Plant dam.

Set Up

Built in 1923, the Ubrug Hydro Power Plant in Sukabumi was set up with an installed power of 5,94 MW on 1st unit and 2nd unit and 6,48 MW on the 3rd unit resulting in sum total of 18,36 MW. However, at present, the actual total power only generates 15,045 MW, a smaller number than its initial capacity, due to the lack of water discharge. Based on the measurement data, the load of the generator has experienced a decrease of power in normal field operation with a peak load of 9,5 MW and the lowest of 6 MW. On daily operations, only 2 generators are being operated, leaving the 3rd generator unoperated. This is due to the aging hydroelectric power plant on the location and the transition of forest functions in the upstream area, that serves as water absorption, to settlements of residents, and industrial estates. The other and the most salient cause is the waste carried by the Cicatih River coming along with the flow of water in the conduit.

This study aims to determine the technical application of picohydro power plant (making design and application test) in Pandansari Village, Wanayasa District, Banjarnegara Regency. The result of technical analysis of picohydro power plant is capable of producing 7.200 watt or 7,2 kilowatts of electric power. Based on the observation and calculation of water discharge in July-August 2017, the water debit required to run the generator on picohydro power plant is insufficient (less than 30 liters / sec) due to the months already entering the dry season in Banjarnegara Regency and also because some of the water debit is used by waterwheel to increase water supply to the water container / reservoir belonging to the people of Pandansari Village. During the dry season, the picohydro power plant can be used when operated alternately with a water mill or set the time of use for each water mill used in the morning until late afternoon, while the picohydro power plant is used during the afternoon until night or early morning when people need electricity for their daily needs. The next alternative is to place a second picohydro / turbine generator under the first turbine utilizing waste water from the first turbine with a height difference of at least 2 meters or more. If during the rainy season, there is a very heavy flow of water from above then the overflow can be disbursed / dumped down through the overflow channel so that the performance of the picohydro generator is not disturbed

Based on the performance test results, Pico-Hydro Power Station can work well. This can be seen from the indicators of high water flow discharge can rotate the turbine quickly during the rainy season the flow of water will be higher turbine will also spin faster. Water discharge is very influential on the rotation of the generator, if the water discharge is high then the charging will be faster. Conversely when the water discharge decreases the charging will be long. The average water discharge of 0.061 - 0.065 can rotate the 371 rpm generator producing an average voltage of 17.5 volts. At a voltage generated from an inverter of 220 Volts can supply a number of 5-sized lamps 15 Watt. The result of the generator test produces a voltage of 12 V AC with a current of 2 Ampere converted to an inverter DC voltage to AC to 220 V with 100 Watt power. Keywords : pico-hydro, 3 phase AC generator,  water discharge AbstrakPenelitian ini bertujuan untuk merealisasikan sebuah Pembangkit Listrik Tenaga Pico-hydro yang dapat digunakan untuk penerangan jalan seputaran kebun salak, serta mengetahui unjuk kerja dari pembangkit listrik tenaga pico-hydro yang nantinya dapat digunakan untuk kebutuhan energi listrik seperti penerangan jalan.
