摘要
为给“电力—信息—社会”深度耦合下的电力数据融合提供参考,对电力数据融合的基本概念、抽象化结构、关键技术及应用场景进行综述性讨论。首先讨论了目前电力数据融合的必要性和存在的挑战;其次介绍了其基本概念和3个层次的抽象化融合结构;接下来对包括贝叶斯网络、D-S证据理论及深度学习等常用的关键技术进行了归纳;并从结构层次的角度对故障诊断、负荷预测等应用场景进行了讨论;最后对未来多模态、跨层次、全范围的网状融合结构进行了综合性描述。
To provide references to the power data fusion under the deep coupling "power-information-society",the basic concepts,abstract structures,key technologies and application scenarios of power data fusion are summarized and discussed.Firstly,the necessity and challenges of power data fusion are discussed.Secondly,the basic concepts and three levels of abstracted fusion structure are introduced;Next,the commonly used key technologies are summarized including Bayesian network,D-S evidence theory and deep learning,etc.The application scenarios such as fault diagnosis and load forecasting are discussed from the perspective of structure level.Finally,a comprehensive description of the multi-modal,cross-level,full-scale reticulated fusion structure is given.
