Investment Control System In Hydropower Research And Application

For a hydropower project with long construction period and huge investment, how to control the investment, reduce the project cost effectively and increase returns on investment is an important issue needed to resolve in China's current water projects. So it is necessary to design and develop a system which meets the actual construction projects in China and be based on a large relational database management system (schedule management system, investment management systems, quality management systems, etc.). This thesis is in close connection with China's construction project management, ERP, investment controlling and the hydropower project of Ertan Hydropower Development Company, Ltd. We designed the project investment control systems and completed the test of system operation.This thesis first introduced the development of construction project management, the emergence and application of ERP and illustrated that it is important to control the investment in hydropower projects. Second, after in-depth study of project investment control's definition, classification, control methods and techniques, we proposed investment control system and described Earned Value in detail which is used widely. Then we illustrated that it is important to use Earned Value Analysis for construction project fund analysis. We studied the design of investment control system deeply which is based on investment control of Ertan Hydropower Development Company, Ltd and explore the feasibility of ERP system. This thesis introduced investment budget, contract management and other major modules. Finally, we used the data of Guandi Hydroelectric Project and Jinping Hydroelectric Project of Ertan Hydropower Development Company, Ltd to test investment control system. We used Earned Value to analysis the investment, deviation and estimate at completion. The chart show fund and construction schedule of Guandi Hydroelectric Project and Jinping Hydroelectric Project. Then critical index displayed the comprehensive state of project investment and we made the conclusion that the two projects were behind the schedule or overspending and poor comprehensive condition. We analyzed the reasons for deviation of investment and proposed corrective measures. The successful analysis of the actual status of project investment verified the system operated well and has accomplished its intended purpose.
