The survey team collected relevant information from the authorities of Iraq, CPA, and Iraqi local consultants, then prepared a short list of the prospective projects with their preliminary designs and cost estimates. Among the shortlist, implementation of seven projects of grant assistance were decided and announced by the Government of Japan. Meanwhile, in order to evaluate the possibility of projects such as mobile power station as subsequent grant assistance, JICA conducted Preliminary Study for Reconstruction of Iraq (Phase 3) form August until October, 2003, upon the request by the Government of Japan. During the above study, it was turned out that supply of natural gas by Iraqi side, which was the prerequisite condition for the mobile power station, would be difficult in Samawah. At the same time, Iraqi side strongly requested construction of a diesel power plant of 15 MW x 4 nos., which would use heavy fuel oil that was available in Samawah. The Government of Japan took the above into consideration, and for the purpose of dealing with the serious power shortage in Iraq, requested JICA to conduct additional study to evaluate the possibility of large scale diesel power plant as a alternative of the mobile power station plan. Upon this, JICA dispatched the study team for Preliminary Study (Phase 4 / Outline Design Study on the Project for Construction of Diesel Power Station in Samawah) to Amman in three times in November, 2004, February and May 2005. The study team discussed with officials from the Ministry of Electricity, the Ministry of Oil, and Muthannna Governorate in Iraq, then confirmed the contents of the requested project. Besides, the study team surveyed current situation of power supply in Muthanna Province and Samawah, and collected basic data related to propriety and possibility of the requested project with assistance of local consultants in Iraq. Based on such collected information, outline design of the project with its cost estimate was prepared. As a result of the study mentioned above, it was confirmed that due to damages by the war, power supply in whole country of Iraq is still under constraint, and this also frequently forces power outage in Samawah, Muthanna province. Under such circumstances, the Government of Iraq aims to improve power supply condition urgently by constructing and/or rehabilitating the power facilities, and thus to accelerate the reconstruction of Iraq. This project is to construct a diesel power station in Samawah city to improve the currently power shortage problem in the area. Power shortage which is serious problem at present in Samawah will be substantially improved by commissioning of the power station of the project, and stable power supply to the region inhabitants would be realized. The summary of necessary components to attain this project is shown below. (a) Construction of a new power plant (output of 60 MW). (b) Installation of 132kV interconnecting facilities and additional electrical equipment in Old Samawah substation. (c) Construction of fuel pipeline which is connected between new power station and Samawah oil refinery. (d) Relocation of existing 132kV transmission line. (e) Training for operation and maintenance. (a) Construction of a new power plant (output of 60 MW). Four numbers of diesel engine generator of 15 MW will be installed with the auxiliary equipment such as fuel oil system, lubricating oil feeding equipment, cooling system equipment, air intake and exhaust system, etc. Engine stroke type will not be restricted to either 2-stroke (low speed) or 4-stroke (medium) engine. (b) Installation of 132kV interconnecting facilities and additional electrical equipment in Old Samawah substation. For the interconnecting the new power station with the existing Old Samawah substation, two circuits of 132 kV underground power cables will be installed from the 132 kV switchyard in the new power plant to the busbar, which is to be extended, in the substation. (c) Construction of fuel pipeline which is connected between new power station and Samawah oil refinery. To transfer the heavy fuel-oil from the existing Samawah Oil Refinery to the new power station, underground type fuel-oil pipeline of about 7.5 km will be constructed. (d) Relocation of existing 132kV transmission line. Relocation of the existing 132 kV transmission line, 2 circuits of Sawa – Old Samawah section, will be executed in advance for the smooth implementation of the Project. (e) Training for operation and maintenance. The plan of the personal education and training for operation and maintenance is consisted of the following 3 stages. 1) Stage-I: Basic education 2) Stage-II: Training at manufacture’s factory 3) Stage-III: Training at Site The work execution of this project will require 20 months from the conclusion of the contract for construction to completion of the project. Items to be executed by the Iraqi authorities in case that a grant aid project from Japan is executed are as follows: (a) Assisting customs clearance at ports of entry into Iraq (b) Getting clearance from relevant authorities which may be necessary within Iraq for the execution of the Project,

  • Emergency Diesel Generator Reliability Study
    Emergency Diesel Generator Reliability Study 1 EDG SYSTEM DESCRIPTION This analysis focused on the ability of the EDG train to start and load its associated safety- related bus for a specified mission time. For the purposes of this study, an EDG train is a diesel engine, electric generator, and the associated support subsystems necessary to power and sequence the electrical loads on the safety-related bus. Typically, two or more EDG trains constitute the onsite emergency ac power system. All but one of the plant designs in this study include the capability for at least two EDG trains to supply power to the plant using independent safety-related buses. The one exception is at Millstone 1 where one EDG train and a gas turbine generator train supply ac power to the emergency ac power system. In some cases, a swing EDG train is used that can supply power to more than one plant (but not simultaneously) such that two plants will have a total of only three EDG trains: one EDG train dedicated to each specific plant and the third, a swing EDG system, capable of powering either plant. Each EDG train uses combinations of one or two diesel engines powering one ac electrical generator. The typical EDG train comprises one diesel engine per generator. In this study, two diesel engines powering one generator were considered as one EDG train. Diesel engines used for fire pumps, specific Appendix R purposes, or non-class 1E backup generators, were not included in the study. Neither was the high-pressure core spray (HPCS) EDGs included in this study.

In this project, a variable speed diesel generator (VSDG) uses a rotating stator driven by a compensator motor. At lower loads, the stator turns in the opposite direction of the rotor, a process that can be used for purposes like maintaining a fixed relative speed between the two components of a generator. This allows the diesel engine to turn at a lower speed (same as the rotor) and to increase its efficiency. The present research addresses the control of the compensator motor driving the generator’s stator using a variable-frequency drive that adapts the speed to its optimal value according to the load. The performance of the proposed control strategy was tested using a Freescale microcontroller card programmed in C-code to determine the appropriate voltage for the variable-frequency drive.

  • Efficient Operation of Diesel Generator Sets in Remote Environments
    Efficient Operation of Diesel Generator Sets in Remote Environments Kaitlyn R. Wheeler Thesis submitted to the faculty of the Virginia Polytechnic Institute and State University in partial fulfillment of the requirements for the degree of Master of Science In Mechanical Engineering Alfred L. Wicks, Chair Douglas Nelson Steve C. Southward May 9, 2017 Blacksburg, VA Keywords: mobile hybrid power system, fuel consumption, energy storage, diesel engine, generator © 2017, Kaitlyn R. Wheeler i Efficient Operation of Diesel Generator Sets in Remote Environments Kaitlyn R. Wheeler Abstract Diesel engine and generator sets (gensets) have been extensively used for standby and remote power generation over the past hundred years. Due to their use for standby power, these diesel gensets are designed to operate in conjunction with the grid, which relates to a fixed speed operation with a 60 Hz AC output. For operation in remote conditions, such as military and disaster relief applications, this fixed speed operation results in limiting the power output available from the engine, as well as the overall efficiency of the system. The removal of this grid connectivity requirement could result in an increase in system efficiency. At a given load, the engine operates more efficiently at lower speeds, which corresponds to an increase in the system efficiency. This low speed operation also results in lower power output. Knowledge of the load is important in order to determine the most efficient operating point for fixed speed operations. Operating at a higher power output for a given speed also results in higher system efficiency. The addition of a battery pack will allow for a higher apparent load, resulting in higher operating efficiency.

Renewable off-grid electricity supply is one alternative that has gained attention, especially with areas lacking a grid system. The aim of this paper is to present an optimal hybrid energy system to meet the electrical demand in a reliable and sustainable manner for an off-grid remote village, Gwakwani, in South Africa. Three off-grid systems have been proposed: (i) Photovoltaic (PV) systems with a diesel generator; (ii) Photovoltaic systems and battery storage; and (iii) Photovoltaic systems with diesel generator and battery storage. For this analysis, different size of photovoltaic panels were tested and the optimal size in each scenario was chosen. These PV sizes were 1, 0.8, 0.6 and 0.4 kW. The optimization between these sizes was built based on three main objectives.

    Preprints (www.preprints.org) | NOT PEER-REVIEWED | Posted: 25 August 2021 doi:10.20944/preprints202108.0485.v1 Potential for Increased Rural Electrification Rate in Sub-Saharan Africa using SWER Power Distribution Networks M. E. Irechukwu and A. T. Mushi Department of Electrical Engineering, University of Dar es Salaam, P.O. Box 35131, Dar es Salaam – TANZANIA Abstract—Rural electrification rate (RER) in Africa is still low to date. Several countries in Sub-Saharan Africa have tried to address this problem using conventional single-phase two-wire or three-phase three-wire systems, however at large costs due to the nature of dispersed rural load centers, low load demand, and low population density. Another solution of off-grid generation creates associated health problems. Therefore, this paper undertakes a review of a single wire earth return (SWER) network as a RER improvement solution. The paper undertakes intensive literature review to elucidate challenges and solutions to the implementation of SWER technology. Advantages of SWER technology discussed make it the choice for RER improvement in Sub-Saharan African countries. After that, a case study is selected in rural Tanzania, and a preliminary SWER network design is undertaken. Index Terms—Single wire earth return (SWER), power distribution networks, rural electrification rate (RER). I. INTRODUCTION Majority of grid-connected rural electrification (RE) technology in Africa are the single-phase two-wire (SPTW) distribution system and the three-phase three wire (TPTW) distribution system, called conventional technologies. Mahanthege (2015) cited a study that presented data of rural electrification rate (RER) in Sub-Saharan Africa at about 14.2%.
