2016 : Thermodynamic study on a combined cycle power plant of 500 MW under various loads using Cycle-Tempo
Dr.Ir. Budi Utomo Kukuh Widodo M.E.
Plant heat rate is affected by the gas turbine and steam turbine generated power. The plant heat rate is altered under various loads. Therefore, it is necessary to conduct a further study regarding the influence of the gas and steam turbine load alterations upon the heat rate of the plant. This study is carried on by a commercial software Cycle-Tempo. The object is to simulate a combined cycle power plant of 500 MW. The power plant operates under the scheme of 3-3-1 (3 gas turbines, 3 HRSGs and 1 steam turbine) in daily operations. In some lower loads, it may operate under the scheme of 2-2-1 or 1-1-1. Specification of the apparatuses and data used in the study are those from the existing heat balance. The simulation is performed with four variations of load (50%, 75%, 100% and 110%) applied upon both gas and steam turbines, in accordance with the total power to meet the customer needs and heat balanceÂ …
