Units and Power Estimations
Power: watts [W] or Kilowatts [kW] 1 kW = 1000W
Flow: 1 m³/s = 1000 l/s
Gross heat: height difference the water "falls down"
Net head: a little smaller than gross head. Gross head deducted by energy loss due to friction in penstock
Potential power ('electric)' is calculated as follows:
Power [W] = Net head [m] x Flow [ l/s] x 9.81 [m/s²] (est. gravity constant) x 0.8(turbine/generator efficiency)
Potential power is estimated as follows:
Power output [W] = height [m] * flow [l/s] * 8
More accurate estimations take into consideration:
● exact net head (intake to powerhouse)
● exact flow (constant during the years)
● combined efficiency of turbine and generator (depends on quality, est. 60% = 0.6)
The Water Turbine Generator Hydropower uses water turbine as the prime mover to convert water energy into electricity. It is mainly composed of rotor, stator, frame, thrust bearing, guide bearing, cooler, brake and so on. It is generally cooled with closed circulating air. When water flows through the turbine, it converts the water energy into mechanical energy, and the rotating shaft of the turbine drives the rotor of the generator to convert the mechanical energy into electrical energy and output it. Besides, the Water Turbine Generator Hydropower has the advantages of high efficiency, high speed, compact structure, sophisticated design, simple operation as well as durability. It is the main power equipment for generating electricity in hydropower stations. It wins a good reputation among clients due to high performance.
