To be a B.Sc engineer from Daffodil International University, we have to take a four credit course like EEE-499 (Thesis/Project). It is declared that this project or any part of it has not been submitted elsewhere for the award of any degree or diploma. We are very grateful to Almighty Allah for the successful completion of the work.
Shamsul Alam, Dean of the Faculty of Engineering, a brilliant teacher and excellent human being who brightened up the course of our graduate work. Although this motor is of a lower rating, the concept can be used in an AC pump driven system with fertility. If we use inverter at the output of the DC system, we get AC output which can be used for an induction motor based pumping system.
Introduction
The irrigation system of Bangladesh
To evaluate my project, I followed the above steps using the data obtained during our observation of the project at BARI. My priority is to satisfy the irrigation requirement during BORRO month as it is mostly grown in Bangladesh and has to be planted in Nov-Dec. And groundwater is scarce at this time of year. The pump parameters are calculated from the data. From the chart, we find that our pump delivers 22.04 of water. So we can pump 0.02 water in 8 hours which is sufficient for only 0.287 hectares of land. This data has been fed to the RETS screen and thus gives us the output as to how much daily and annual electricity is needed to irrigate 0.287 hectares of land. The delivered power is 50 W electricity.
In this section, I have highlighted the load that our system must provide. The only load is a 35 W centrifugal pump. Both loads for the proposed case (solar irrigation) and the base case (diesel engine irrigation) are assumed to be the same. This typically ranges from 10 to 20% of this cost. We took 10% of contingency. The cost analysis is shown in figure. The Proposed Case System GHG Summary section provides a description of the emissions profile of the proposed project.
The GHG emission reduction summary section provides a summary of the estimated GHG emission reduction based on the data entered by the user in the previous sections. One of the main benefits of using RETScreen software is that it facilitates the project evaluation process for decision makers. We have also taken the life of the project to be 20 years. The total project is financed by the owner himself, so no grants or subsidies are considered.
Many of the summary items here are calculated and/or entered in the Cost Analysis worksheet and transferred to the Financial Analysis worksheet. The total initial costs are the sum of the feasibility study, development, engineering, power system evaluation. It is the sum of O&M, fuel cost for the proposed case system and debt payments.
The model calculates the net present value (NPV) of a project, which is the value of all future cash flows, discounted at the discount rate, in today's currency. The model calculates the Net Benefit-Cost (B-C) ratio, which is the ratio of the net benefits to the costs of the project. GHG abatement costs are calculated by dividing the project's annual life-cycle savings by the net GHG reductions per year, averaged over the life of the project.
The total annual savings and revenue represents the annual savings and/or revenue realized as a result of the implementation of the proposed case system. The model calculates the annual greenhouse gas reduction income, which represents the income generated by the sale or exchange of the greenhouse gas reduction. For our project, the positive cash flow occurs in the 6th year, and after 20 years of the project, the project will generate about 6104 dollars.
The chart above shows the range of sensitivity for which our NPV will still be feasible to accept this project. The orange colored cells represent the extent of the possibility of survival of the parameter change. In the risk analysis section, the influence of each input parameter on the financial indicator is obtained using standardized multiple linear regression on the financial indicator.

As part of the RETScreenClean Energy Project Analysis Software, an Emissions Analysis worksheet is provided to estimate greenhouse gas emissions. The baseline electricity system and baseline greenhouse energy system summary sections provide a description of the emissions profile of the baseline system. The Financial Analysis worksheet, with its financial parameters input elements (e.g. discount rate, debt ratio, inflation rate, discount rate, etc.) and the output items of calculated financial sustainability (e.g. (eg IRR, simple payback, NPV, etc.), allows the project decision maker to easily consider various financial parameters.
Rather, cost of capital is a broad concept that includes a combination of the costs of all sources of investment funds, both debt and equity. The discount rate used to assess the financial viability of a particular project is also known as the hurdle rate. The total annual costs are calculated by the model and represent the annual costs incurred to operate, maintain and finance the project.
The periodic costs and periodic credits are entered by the user in the cost analysis sheet and transferred here. The model escalates the periodic costs and credits annually according to the inflation rate from year 1 and throughout the life of the project. The results from the financial viability part provide the decision maker with various financial indicators for the proposed case project.
The model calculates the pre-tax internal rate of return (IRR) on equity (%), which represents the actual interest rate return provided by the project equity over the equity. If it is lower than the required return, the project is usually rejected. The equity payback period was referred to “Year-to-Positive Cash Flow.” The model calculates the simple payback period (years), which represents the time it takes for a proposed project to recoup its own initial costs, from revenues or savings. it generates.
The difference between the present values of these cash flows, called the NPV, determines whether the project is generally a financially acceptable investment or not. Net benefits represent the present value of annual income and savings less annual costs, while the costs are defined as the project equity. This value is calculated from the annual net GHG reduction and the GHG reduction credit.
As part of the RETScreen clean energy project analysis software, a sensitivity and risk analysis worksheet is available to help the user assess the sensitivity of important financial indicators in relation to key technical and financial parameters. In each section, there is information on the relationship between key parameters and important financial indicators, showing the parameters that have the greatest impact on financial indicators. Results indicating an unfeasible project as defined by the user. Threshold, will be displayed as orange cells in this sensitivity analysis results table.
Risk analysis allows the user to assess whether the variability of a financial indicator is acceptable or not by looking at the distribution of possible outcomes.
