Проектирование проточной части гидротурбины Токтогульской ГЭС

Abstract

Тема выпускной квалификационной работы бакалавра «Проектирование проточной части гидротурбины Токтогульской ГЭС». В данной выпускной квалификационной работе бакалавра было проведено изучение гидроузла Токтогульской ГЭС. Токтогульская ГЭС расположена на реке Нарын. Сама река Нарын входит в Джалал-Абадскую область Киргизии. Токтогульская ГЭС является второй по значимости ГЭС в Нарын-Сырдарьинском каскаде и второй по мощности ее ступенью. Вступила в эксплуатацию в 1962 году. Был проведен расчет и проектирование гидротурбины на условия работы гидроузла Токтогульской ГЭС. Расчет гидротурбины позволяет получить данные о проточной части и эксплуатационной характеристике Токтогульской ГЭС. В качестве одного из методов исследования выступал численный расчет в программном пакете Ansys CFX. В результате выполнения выпускной квалификационной работы был проведен расчет новой гидротурбины для Токтогульской ГЭС. Была построена эксплуатационная и рабочая характеристики. Было проведено проектирование проточной части гидротурбины, которая включала в себя проектирование рабочего колеса, направляющего аппарата, отсасывающей трубы, спиральной камеры. Также был проведен численный расчет рабочего режима проточной части гидротурбины в Ansys CFX, который позволил получить визуализацию картины течения потока рабочей жидкости.

The topic of the final qualifying work “Design of the flow part of the Toktogul hydroturbine”. In this bachelors final qualifying work, a study of the Toktogul hydroelectric power plant was conducted. Toktogul HPP is located on the Naryn River, in the Jalal- Abad region in Kyrgyzstan. The second hydroelectric power station in the Naryn- Syrdarya cascade, at the same time, being its most powerful stage. It was commissioned in 1962. The calculation and design of the hydro turbine for the operating conditions of the Toktogul hydroelectric power plant was carried out. The design and calculation of the hydro turbine is necessary to obtain optimal data on the flow part and operational characteristics of the Toktogul HPP. Numerical calculation in the Ansys CFX software package was used as one of the research methods. As a result of the completion of the final qualification work, the calculation of a new hydro turbine for the Toktogul HPP was carried out. Operational and operational characteristics were built. The design of the flow part of the hydraulic turbine was carried out, which included the design of the impeller, guide device, suction pipe, spiral chamber. A numerical calculation of the operating mode of the flow part of the hydraulic turbine in Ansys CFX was also carried out, which made it possible to obtain a visualization of the flow pattern of the working fluid flow.
