STUDY ON RULE CURVE DEVELOPMENT FOR HYDRO ELECTRIC POWER (HEP) DAM OPERATION. CASE STUDY: MURUM HEP DAM

https://doi.org/10.33736/jcest.305.2016Abstract
An operation rule curve of a dam provides specific on the target elevation of the
reservoir. This can vary throughout the year. This is an indication to the reservoir operator of
activities to conduct for various situations involving reservoir and the hydrologic conditions.
This rule curve shall apply to Murum dam solely for power generation purpose. The
decisions on when and how much to release will impact the ability to pass a flood as well as
hydropower capacity. The main objective of this research is to select the most suitable
method and to develop the operation rule curves for Murum dam primarily for hydropower
generation. A trial-and-error method has been selected for this study. Reservoir operation
modeling and simulation have been commenced using historical rainfall data, after runoff
was generated by rainfall runoff modellings. Three (3) simulations are conducted for
developing the operation rule curves. They are rule curve according to Sarawak Energy
Berhad’s requirement, ideal rule curve and mean rule curve. All three sets of rule curves are
successfully developed using turbine discharges of the dam as the parameters and to achieve
the target firm energy generation of 635MW.
