Análisis numérico de transientes hidráulicos en el túnel de carga PilatónSarapullo del proyecto Hidroeléctrico Toachi Pilatón

Abstract

The energy development of the country is due to the large hydroelectric projects, among them we have the Toachi Pilatón Hydroelectric that will generate 254 MW of power, it is located between the limits of Cotopaxi, Pichincha and Santo Domingo de los Tsáchilas, near the Alóag highway. -Santo Domingo de los Tsáchilas. This project is focused on simulations of water hammer scenarios in the Pilatón-Sarapullo Exploitation, where the behavior of the hydraulic works of interest will be verified. Adequate knowledge about hydraulic transients is important to take into account the causes, effects and characteristic parameters. The methodology applied to this project is the analysis of the non-permanent flow for pressure ducts through modeling in the Hammer computer program. The scenarios considered for the simulation are: instantaneous load rejection and load acceptance for different flows of interest where the following hydraulic works were taken into account: the load tank located in the catchment, pressure pipe, equilibrium chimney and the valves found in the powerhouse. The tests were carried out in different cases of valve opening and closing with flow rate variation. The results obtained by the software will be analyzed for each case and the necessary information will be selected, such as levels reached in the cargo tank, fluctuation levels, maximum and minimum system pressures. The level reached in the cargo tank shows the need to build a hydraulic work to mitigate damage to the Pilatón-Sarapullo Exploitation system.
