变电站电能质量数据修复方法
摘要：
本发明公开了变电站电能质量数据修复方法；步骤如下：首先，部署所述电能质量的数据监控主机，获取若干电能质量暂态数据；然后，剔除所述电能质量的暂态事件异常数据，获取暂态数据指标正常的若干所述电能质量暂态数据；最后，修复所述电能质量的暂态事件数据。本发明基于电力扰动的传播特性，通过寻找相似记录的方法对缺失数据进行补充，能够有效的避免现有技术中因数据传输容量过大而对传输数据质量产生的不良影响。
摘要（英）：

The invention discloses a method for repairing power quality data of a transformer substation. The method comprises the following steps: firstly, deploying a data monitoring host of the electric energy quality, and obtaining a plurality of electric energy quality transient data; then, eliminating the transient event abnormal data of the power quality, and obtaining a plurality of pieces of power quality transient data with normal transient data indexes; and finally, repairing the transient event data of the power quality. Based on the propagation characteristics of electric power disturbance,missing data is supplemented through a method of searching similar records, and the adverse effect on the quality of transmitted data due to overlarge data transmission capacity in the prior art can be effectively avoided.
