| Post project evaluation is an effective carrier to practice the scientific concept of development. It is an inevitable requirement to improve the project management and the efficiency of investment. According to the "Central Enterprises fixed assets investment project post evaluation guide"(state owned assets supervision and administration planning [2005] No. 92) and the China Power Investment Corporation investment project evaluation management approach "and other relevant documentation requirements, and in the light of the China Power Investment Corporation 2015 post project evaluation work plan, the author carried out the Jianping Haladaokou windfarm new project’s post evaluation.The project is located in the hilly area in the southeast of Haladaokou town of Jianping County, about 5 km from the center of the town. The area is located in the "Three North" winds of our country, is one of China’s wind energy resource rich regions, the development area is about 35km2. 33 standard power of 1500 k W wind turbines are installed, of which the impeller diameter is 77 m. The single blower adopts boost machine change mode, the power system to send to 66 k V booster station connected through 3 35 k V integrated circuit.According to the China Power Investment Corporation investment project evaluation management "requirements of the scope of the evaluation and assessment of the depth, based on the project of the secondary units and project units provide the basic data, the project data collation and analysis of the formation evaluation views on the preparation of project post evaluation report. Post project evaluation point from project started to December 31,2014.Before December 31, 2014,using practical data to analysis. After December 31, 2014 the basic calculating data after this reevaluation confirmed the prediction value were analyzed. IThe main contents of this thesis include: the basic situation of project decision-making, compliance evaluation, financial and economic evaluation, a comprehensive evaluation of the project, summarizes the experience and lessons and later work advice. The project completion final dynamic total investment is 39095.46 yuan, unit dynamic investment is 7898.1 yuan /k W, 2.28% lower comparing with the research budget and 2.28% higher comparing with the initial budge. The 2014 generating capacity for 7320 million kilowatts, electricity 7165 million kilowatts, equivalent annual use hours of 1473 hours of full load, failure rate of abandoned wind 1.73%, abandoned wind power grid electricity rate 13.87%. And research design(Research recommended scheme using hours of 1789 hours) compared in equivalent full load by hour Ratio Research index is 17.3% lower. The problem is mainly due to both the grid consumptive inadequacy and sending limitation, project effective utilization hours below the feasibility study and economic benefits did not reach the research expectations and project abandoned wind rate is far higher than the surrounding projects. This project also achieved some experiences and lessons: new modes of cooperation, the development of wind power resources; optimizing the construction organization design, and striving to make a permanent covering size minimization; unit selection is slightly conservative, the local abandoned wind curtailment pre judgement problem and construction sequence of development of the is not very reasonable. Construct the wind towers reasonably, choose power prediction software scientifically, increase the accuracy of wind resource assessment and power calculation.By calculation, the comprehensive index of the project comprehensive evaluation is: B=RE=0.69, the evaluation result is between 0.6 and 0.8, which turns out to be a good level. Overall, the project construction and operation is successful. There is a lot of successful experience worth promoting. Meanwhile, there are also some omissions and lessons that need further in-depth summary, for the the reference of future similar projects. |
