Micro Hydro Power Plant (PLTMH) a small-scale power plant that uses
hydropower as its driving force, by utilizing the height of waterfall (head unit
meter) and the amount of water discharge (m3 / s). The principle of PLTMH from
the change of potential water power into electric power with potential power is
hydropower because it is at an altitude, kinetic power is hydropower because it has
speed, mechanical power is the speed of water that continues to turn the runner or
blade of the turbine. The goal is to design a micro hydro power plant with a 5 meter
high water fall using a crossflow turbine with a power of 50 kW, the design of
mechanical components using Solidworks software. And simulate the electricity
using etap 12.6.0 software. The results of the mechanical design of the generator
used 55 kW power capacity refers to technical data from the IEC frame size type
Y2 250M 2 and crossflow turbine design with 5 meters high water fall discharge
1.3 m3 / s and turbine efficiency 82% of the power generated is only 52, 2 kW.
Electrical design from the Main Distribution Panel (MDP) used by MMCB
NSX160F 3P 160 A protection, and 1: 100 scale current transformers, cables on
the transmission used a sudrado type AAAC/S 300 mm2 along 1 km, the Sub
Distribution Panel (1 km) SDP) protection used MCCB type TM80D 115 A, the
cable used NFA2X AAC / S type 2x16 type sudrado cable along 10 m. And the
design of a micro hydro power plant (PLTMH) with 50 kW power requires an
estimated production cost budget of Rp. 499,058,000. Calculation and BEP value
of 2 year + 6 month + 3 day or can break even before the economic life of the plant
is 10 years
