Effective Head

HOMER Logo

Type:	Intermediate Variable
Units:	m
Symbol:	hnet

One can model the friction pressure loss in the pipeline between the intake and the turbine as a loss in head. The effective head is the actual vertical drop minus this head loss. HOMER calculates the effective head (or net head) using the following equation:

equations_h_net

where:
	h	= available head [m]
	fh	= pipe head loss [%]

HOMER uses the effective head to calculate the power output of the hydro turbine in each time step.
