摘要
提出了一种新型煤矿电能质量评估方法。该方法将基于粗糙集理论确定的客观权重和由层次分析法得到的主观权重进行线性加权,计算出电能质量各指标综合权重;采用动态时间规整算法计算加权化后的电能质量指标序列与理想参考指标序列的匹配系数,得到电能质量评估等级区间,实现对煤矿电能质量的综合评估。实际应用结果验证了该方法的可行性和有效性。
A new evaluation method for power quality of coal mine was proposed. Comprehensive weight of each power quality index is calculated through linear weighting of objective weight determined by rough set theory and subjective weight obtained by analytic hierarchy process. Matching coefficient between weighted index sequence and reference index sequence of power quality is calculated by use of dynamic time warping method, and evaluation level interval is got, so as to realize comprehensive evaluation for power quality of coal mine. The practical application result verifies feasibility and effectiveness of the method.
