摘要:

电网调控系统服务范围的扩大使得电力调度数据出现爆炸式增长,量测数据不一致、准确性低等数据质量问题日益突出,如何快速有效地实现多级电网调控量测数据质量诊断与评估成为亟待解决的难题。围绕多级电网调控运行管理业务需求,首先提出考虑长时间尺度功率平衡及多源关联分析的调控量测数据校验算法,实现功率不平衡、多源不一致等异常数据的快速研判;其次提出基于模糊层次分析法的量测数据质量评估方法,构建基于Spark的电网调控多源量测数据质量综合评估系统,为大电网数据价值深度挖掘和调控精益管理提供技术支撑。

Abstract:

The rapid expansion of the service scope of the power grid control system has caused the explosive growth in power dispatching data.Data quality issues such as consistency and accuracy of measuring data have become increasingly prominent.Therefore,how to quickly and effectively realize the measuring data quality diagnosis and evaluation of multi-level power grid control has become an urgent issue.Focusing on the business requirements of multi-level power grid dispatching and control operation management,a measuring data verification algorithm considering long time scale power balance and multi-source correlation analysis is proposed to realize the rapid research and judgment of abnormal data such as power imbalance and multi-source inconsistency.Secondly,a measuring data quality evaluation method based on fuzzy analytic hierarchy process is proposed,and a comprehensive evaluation system of multi-source measuring data quality for grid control based on Spark is constructed,which can provide technical support for deep mining of data value and lean management of the control in large power grids.

Key words: multi-level grid control, long time scale power balance, multi-source correlation analysis, fuzzy analytic hierarchy process, comprehensive evaluation of data quality
