This post is continuation of my first post about my participation in workshop on microhydro power plant in national seminar on instrumentation, control, and automation. Please read the first post first to get overall picture of the workshop.
I am lucky to see some of main equipments in microhydro power plant workshop. Picture below is example of microhydro power plant for study purpose.

Mr. Kusetiadi Raharjo was explaining how the equipment works.
In this demo, I saw three types of water turbine, which are Pelton turbine, Crossflow turbine, and Kaplan turbine.
Pelton turbine is suitable when there is a relatively high head but very low water debit. In this demo, pelton turbine is direct coupled with induction motor and capacitor.
Pelton turbine is directly coupled with induction motor.
Crossflow turbine is suitable for relatively high head (higher than Kaplan turbine, but lower than Pelton turbine) and low water debit (lower than Kaplan turbine, but higher than Pelton Turbine). The Crossflow turbine is coupled with generator by using belt.
Kaplan turbine is suitable for low head but high water debit.
Besides hydropower plant, the workshop is also explained about pumped hydro & bank energy. Pumped storage power plant can be utilized as bank of energy. It can also be utilized as flood control and power management. Example of pumped storage in Indonesia is in Upper Cisokan Pumped Storage Power Plant. The capacity is 1040 MW.
And the last picture is ME, asking some questions to hone my understanding about hydropower plant.
