Abstract
This reservoir is a multipurpose reservoir which has a function as a hydroelectric power plant, flood control, fisheries and recreation areas. Koto Panjang Hydroelectric Power Plant operates three turbine and generator units, but in the dry season, this hydroelectric power plant has operated one turbine and generator unit so the power produced is not optimal. In the same season, Koto Panjang Hydroelectric Power Plant also operated three turbines and generators but only produced â‰¤ 35 MW of electricity by percentage < 50 % which is â‰¤ 30,702 % of the maximum power from operating three turbine and generator units. The purpose of this research is to determine how much mainstay discharge can be used by Koto Panjang Hydroelectric Power Plant, what is optimization will be used for Koto Panjang hydroelectric power plant, how much power can produce from its optimization, and how is comparison before the optimization of electrical power and after the optimization of electrical power. The method used in this research is the Penman empirical method to calculate the evaporation value. The mainstay discharge for hydroelectric power plant outflow discharge is currently calculated using the electrical power formula. The mainstay discharge for hydroelectric power plant outflow discharge after optimization is calculated using mass curve method. Furthermore, the hydroelectric power plant outflow discharge has obtained is analyzed in the water balance table using the sequent peak analysis method. The results obtained from the calculation are the current mainstay discharge of hydroelectric power plant, which is 305,319 m3/s with a percentage of 51,995 %. The mainstay discharge of hydroelectric power plant after optimization is 384,465 m3/s with a percentage of 39,235%. Optimization is done by adjusting the outflow discharge to the volume of water in the storage at that time. Its outflow discharge is the mainstay discharge from the mass curve analysis, which is 384,465 m3/s. The result of this adjustment is shown in the column Kt (storage volume or excess volume in a day) which is zero in the water balance table. The electric power after optimization is 13.302,315 kWatt in the dry season and 143.551,645 kWatt in the rainy season. The current electricity generated by hydroelectric power plant is 13.302,315 kWatt in the dry season and 114.000 kWatt in the rainy season. Therefore the electric power generated by hydroelectric power plant after optimization has increased from the electric power before it is optimized which is 29.551,645 kWatt. Because the increasing of the electric power exceeds the capacity of the current hydroelectric power plant generator, there is an addition 1 generator which is 30.000 kWatt or 30 MW.
