134. OperatingHeadToMaxRelease

This function performs a lookup in a Power Reservoir object's Max Turbine Q table based on a given operating head, and then evaluates to the corresponding maximum turbine release.

Description Find the maximum turbine release at a given reservoir operating head. Type NUMERIC Arguments Type Meaning 1 OBJECT power reservoir object 2 NUMERIC operating head 3 DATETIME datetime context for unit conversions Evaluation The operating head argument is looked up in the Operating Head column, of the Max Turbine Q table, of the power reservoir object argument, to determine the Turbine Capacity. If the exact operating head is not in the table, the lookup performs a linear interpolation between the two nearest bounding operating heads and their corresponding turbine capacities. Mathematical Expression Comments If the object is not a power reservoir, the function aborts the run with an error. If the Power Reservoir does not have a Max Turbine Q table, Plant Power Coefficient must be selected as the Power selected method, or this function exits the rule with an early termination.

Syntax Example:

OperatingHeadToMaxRelease(%"Hoover Dam", 508.63 "ft",
@"t")

Return Example:

152.23 "cms"
