Numerical Analysis of the Hydraulic Machinery Transition Process in a Hydropower Station in Tajikistan
To ensure the safe and economic operation of the Sebzor Hydropower Station in Tajikistan,numerical analysis is carried out in MATLAB software with the mathematical model for unsteady flow in pressurized pipelines and the char-acteristic line method to study the typical operating conditions in large and small fluctuation transition processes of the station.Then,based on the calculation results,operation parameters such as the maximum pressure of the distribution pipes and the maximum speed of the units are determined,which provide useful basis for the structural design of the wa-ter diversion system.Also,reasonable suggestions and requirements are proposed for the stable operation mode of the u-nits.
