基于能值分析法的风电场可持续性发展研究

Study on sustainable development of wind farm based on energy synthesis

简介目前我国风电行业的"投资"与"收益"的相对"异步",需要寻求一种风电场可持续发展的综合评价方法的现状。提出采用太阳能值理论来研究风电场可持续发展的方法和采用能值产出率、环境负载率、能值投资率、可持续性指标及可再生能值比五个指标来分析风电场可持续发展程度的量化指标,绘制风电场能量系统图,通过能流归类最后得到风电场综合能值系统图。以A、B两个风电场为例,通过能值及指标计算得知:B风电场的能值转换率低于A风电场,即B风电场的生产效率更高;虽然B风电场的ESI值高于A风电场,但是两个电场都需要通过降低ELR值同时增大EYR值来进一步提高其可持续发展能力。

Existing＂investment＂and＂income＂of wind power industry are asynchronous,thus,a comprehensive evaluation method is needed for assessing the sustainable development of wind farm.Solar energy synthesis theory was proposed,and five quantitative indicators were adopted for analyzing the sustainable development degree,including EYR,ELR,EIR,ESIand PR.The integrated energy value system diagram was obtained by energy flow classification,after generating the energy system diagram of wind farm.Taking Aand B wind farm as examples,the calculation of energy value indicates that the energy conversion rate of Bis lower than that of A,and B wind farm appears higher production efficiency.Although the ESI value of Bis higher than A,decreasing the ELRvalue and increasing the EYRvalue are the same path for two wind farms,to further improving the sustainable development ability.
