摘　　要：针对电力调度系统中数据在时间上存在粒度偏移和误差的问题,提出一种基于时间延迟技术的电力调度数据采集与入库时间对齐方法。在数据采集模型中将设备节点产生的电力调度数据按时间戳进行泛化,以数据帧的形式发送至数据库,从而解决传感器采集中数据粒度不一致问题。将入库数据根据时间戳对齐到标准时间上的时间切片,结合初始数据时间戳计算时间偏移,对后续数据进行归类修复,建立从数据采集到数据入库过程的一体化数据对齐。分析表明所提方法可有效解决时间偏移与误差问题,提升电力调度数据的采集质量。Aiming at the problems of data granularity offset and errors in time in the power dispatching system,this paper proposes a time alignment method of power dispatching data collection and inbound time based on time delay technology.The power dispatching data generated by device nodes are generalized by timestamps in the data collection model and sent to the database in a form of data frames to solve the problem of inconsistent data granularity in sensor collection.The inbound data is aligned to the time slices on standard time according to the timestamps.Combined with the initial data timestamps,the time offset is calculated,the subsequent data is categorize and repaired,and integrated data alignment from data collection to data inbound is carried out.The analysis shows that the proposed method can effectively solve the problems of time offset and errors as well as improve the quality of power dispatching data collection.
