Проектирование и расчёт гидроагрегата Морской МГЭС

Abstract

Целью данной работы является проектирование и расчёт гидроагрегата Морской МГЭС. В соответствии с поставленной целью, были сформулированы следующие задачи работы: определить основные параметры гидроагрегатов, их тип и количество; спроектировать расчетную область проточной части модельной гидротурбины; провести трехмерный расчет вязкого течения в проточной части модельной гидротурбины на расчетном режиме; разработать бизнес – план строительства Морской ГЭС. В ходе работы было принято решение оснастить данную ГЭС четырьмя горизонтально – капсульными гидроагрегатами с пропеллерными рабочими колесами. Была спроектирована проточная часть и рассчитаны основные параметры гидротурбины, построены зона работы и эксплуатационная характеристика гидротурбины. Определены основные параметры генератора. Спроектирована расчетная область проточной части модельной гидротурбины ПЛГ-548, включающая в себя области рабочего колеса, направляющего аппарата и отсасывающей трубы. Проведен расчет трехмерного течения вязкой жидкости в проточной части гидротурбины на расчетном режиме работы с использованием современных программных комплексов. В результате чего на основе имеющейся универсальной характеристики модели гидротурбины была верифицирована ее математическая модель на расчетном режиме работы. Разработан бизнес – план строительства малой гидроэлектростанции и рассчитаны основные показатели инвестиционного анализа.

The aim of this work is the design and calculation of the hydraulic unit of the Morskaya hydroelectric power plant. In accordance with the goal, the following tasks were formulated: to determine the main parameters of hydraulic units, their type and quantity; to design the computational domain of the flow part of the model hydraulic turbine; conduct a three-dimensional calculation of the viscous flow in the flow part of a model hydraulic turbine in the design mode; to develop a business plan for the construction of an offshore hydroelectric station. In the course of work, it was decided to equip this hydroelectric power station with four low head hydropower with bulb units. The flow part was designed, and the main parameters of the hydraulic turbine were calculated, the working area and the operational characteristics of the hydraulic turbine were constructed. The main parameters of the generator are determined. The design region of the flow part of the PLG-548 model hydraulic turbine was designed, which includes the areas of the runner, guide vane, and draft tube. The three-dimensional flow of a viscous fluid in the flow part of a hydraulic turbine was calculated at the calculated operating mode using modern software systems. As a result, based on the available universal characteristics of the model of a hydraulic turbine, its mathematical model was verified on the calculated operating mode. A business plan for the construction of a small hydroelectric power station was developed and the main indicators of investment analysis were calculated.
