塔吉克斯坦某水电站水力机械过渡过程计算分析

Numerical Analysis of the Hydraulic Machinery Transition Process in a Hydropower Station in Tajikistan

为了保证水电站的安全经济运行,采用有压管道非恒定流数学模型和特征线法,并使用计算机软件MATLAB对塔吉克斯坦塞布佐水电站的大波动和小波动过渡过程典型工况进行数值计算研究。根据计算结果和数值分析,确定配水管最大压力、机组最大转速等参数,为引水系统结构设计提供依据,并对机组的稳定运行方式提出合理的建议和要求。

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 characteristic 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 water diversion system.Also,reasonable suggestions and requirements are proposed for the stable operation mode of the units.
