  • Engineering Geology of Randenigala Hydro Power Project Site
    ENGINEERING GEOLOGY OF RANDENIGALA HYDRO POWER PROJECT SITE by A.U. Gunasekera SYNOPSIS Geotechnical investigations for a hydropower project are conducted in stages, in order to establish the engi­ neering geological conditions, which invariably here a direct impact on the selection of locations of structures, methods of foundation treatment/stablisation and con­ struction of foundations/substructures etc. Hence, it is of utmost significance to perform a very comprehen­ sive engineering geological study, for such projects, as it will also, in addition to the above mentioned facts af­ fect the economic feasibility of the project. This paper shows how geotechnical investigations were conducted for the Randenigala Hydro Power Project, Figure 1 - Map of Figure 2 - Randenigala including the different types of methods utilized along Sri Lanka Project Area with their purpose.

  • 1 SRI LANKA: Integrated Watershed & Water Resources Management
    SRI LANKA: Integrated Watershed & Water Resources Management Project Executive Summary of Safeguard Documents (A) ENVIRONMENT AND SOCIAL MANAGEMENT FRAMEWORK (ESMF) Background: The Global Climate Risk Index 2019 ranks Sri Lanka as the second among the most affected countries of the World by climate change. The impacts of climate change are already starting to show with severe and long duration droughts followed by severe flooding and landslides occurring almost every year in several parts of the country. The island’s major rivers originate from the mountains in the central region and radiate out to the lowlands to distribute water across the country; making the central region the main watershed of the country. Over the years, forest cover in the upper watersheds have been extensively modified, degraded and fragmented. The natural montane wetlands and marshlands have been converted to agricultural lands and other anthropogenic land uses. Lowered capacity for water infiltration and retention in the upper watershed areas has contributed to increasingly variable and uncertain water availability affecting agriculture and industrial growth, community and individual livelihoods, and even lives. Studies show that these trends are likely to exacerbate, and the wetter areas of the country would eventually become wetter and the drier areas drier. Unplanned settlements, industrial projects, and maladaptive agricultural practices are creating additional water stresses. It is estimated that approximately 80% of the river basins have greatly reduced their water quality and quantity due to these unplanned activities. Sri Lanka’s water resources are critically important to sustain the country’s socio-ecological integrity and development goals. As such, the Government of Sri Lanka (GoSL) has initiated many watershed and water resources management programs focusing on various geographical areas of the country to address these challenges.

  • Pumped Energy Storage System for the Randenigala Hydropower Plant in Sri Lanka
    Pumped Energy Storage System for the Randenigala Hydropower Plant in Sri Lanka Duminda Nalin Habakkala Hewage Master of Science Thesis KTH School of Industrial Engineering and Management Energy Technology TRITA-ITM-EX 2018:161 Division of Heat & Power SE-100 44 STOCKHOLM Master of Science Thesis in Energy Technology TRITA-ITM-EX 2018:161 Pumped Energy Storage System for the Randenigala Hydropower Plant in Sri Lanka Duminda Nalin Habakkala Hewage Approved Examiner Supervisors at KTH 2018-06-26 Miroslav Petrov - KTH/ITM/EGI Amir Vadiee, Miroslav Petrov Commissioner Local Supervisor Open University of Sri Lanka Dr. K.A.C. Udayakumar Abstract The main focus of this thesis work is to perform a preliminary evaluation for the introduction of a pumped energy storage system to an existing hydropower plant located on the Randenigala water reservoir in Sri Lanka. The selected power plant is located in an area where farming is done extensively, therefore electrical power generation and release of water for downstream irrigation purposes is to be properly coordinated with relevant authorities. The solution to this situation is to introduce a wind powered pumped energy storage power plant to the Mahaweli hydro cascade for the purpose of saving peak power for around half an hour. A feasibility study was carried out on the utilization of wind energy and excess power to drive the motors of the pumped storage system. Three versions with different numbers of pump motors and wind turbines have been considered to meet the half hour peak demand of the energy storage system. The optimum number of turbines and motor capacities and their number and brand have been selected with view of both energy and water management system.

  • Forum23 植松g Optimization of Multireservoir Operation by Stochastic Dynamic Programming for Moragolla Hydropower Project in S
    Optimization of Multi-reservoir Operation by Stochastic Dynamic Programming for Moragolla Hydropower Project in Sri Lanka International Consulting Operations, Water Resources Division, Water Resources & Energy Department, Sohei UEMATSU ○ Keywords reservoir operation, optimization, hydropower, stochastic dynamic programming ○ Outline Development of new hydropower project into an existing river management system sometimes impair the original purpose of the existing system, especially the new project was not considered in the original design of the river system. It is ideally imperative that the operation performance of existing facilities with planned new facilities is optimized together. However, it is practically difficult to optimize complex river management system without efforts to reduce the time for computation of the modern desktop computers. In the article, the optimization study for the Moragolla hydropower project in Sri Lanka is introduced in detail. The project is a newly planned hydropower project in the Mahaweli river system and the project was not originally designed during the first planning of the river management. Therefore the optimization is done with existing facility in the study. This article introduces the study as an example for multi-dimensional optimization. ○Technical Points This article explained as an example of limiting the number of multi-dimension problem. The optimization algorithm applied for the problem is stochastic dynamic programming (SDP). The program algorithm of SDP is expanded for n-dimension problems and applied for a feasibility study of the planned hydropower project, namely Moragolla Hydropower Project. In the study, daily operation of an existing hydropower and the planned Moragolla hydropower is simultaneously optimized with the multi-dimension SDP. ○ Figure, table, and picture Time Step (day) C.A.
