Power Generation Efficiency Evaluation Strategy for
Jinweizhou Hydropower Plant on Xiangjiang River
Abstract: As the power generation efficiency of hydropower plant is closely related to the actual incoming water situation, the new thinking, which evaluates power generation efficiency of the daily regulation hydropower plant according to its actual incoming water situation in one year , has been proposed in this paper, and the power generation efficiency evaluation strategy for Jinweizhou hydropower plant on Xiang river has been built, the strategy is based on the average hour flow into reservoir for the hydropower plant, takes full consideration of rainy-dry, peak-valley electric price and multi-constraints including plant discharge limit from reservoir, water level limit, the sets capacity limit, output power limit, etc, and then makes use of the incremental dynamic programming principle, to finally calculate the idea dynamic curve including the idea dynamic power generation efficiency curve and its corresponding power curve, at last, the comprehensive comparison and analysis between the idea dynamic curve and the actual dynamic curve (including the actual dynamic power generation efficiency curve of the daily regulation hydropower plant and its corresponding power curve) was conducted, which was used as the appraisal criteria of power generation completion situation and employee performance of the Jinweizhou hydropower plant. On this basis, the system to evaluate power generation efficiency of Jinweizhou hydropower plant has been self-developed by Wuling Power Corporation, and the system’s software platform has been built.
