摘　　要：准确的远动数据传输是电网调控的基础,因此保证传输数据的准确性至关重要。随着更多清洁能源并网,传输数据量增长,传统的人工、离线数据校验模式已经无法满足当前情况下的数据校验要求。文章提出了一种远动传输数据的在线自动校验技术,以抽样检测的思想实现在线传输远动数据的自动校验。在电网内部以太网通信环境下,搭建自动校验平台,实现主、厂站点表的自动接收,实现时间断面同一化并提取点表有效信息,再经直接校验算法完成数据校验。通过对某主、厂站实际点表的实验验证选择了比循环冗余校验具有更高校验准确度和速度的直接校验算法实现点表处理后有效信息的校验。仿真验证结果表明,提出的电力远动传输数据在线自动校验技术不仅实现了校验过程闭环自动进行,大大提升校验效率,而且实现了对在线传输的远动数据“端到端”的校验,提高了校验结果的时效性和可靠性。Accurate transmission of remote control data is the foundation of power grid regulation,therefore ensuring the accuracy of transmission data is crucial.With the integration of more clean energy into the grid,the amount of transmitted data will increase significantly,so traditional manual and offline data check modes can no longer meet the current data check requirements.This paper proposes an online automatic check technology for remote control transmission data,which achieves automatic check of remote control data through sampling detection.In the internal Ethernet communication environment of the power grid,an automatic check platform is built to achieve automatic reception of the main and plant station tables.Subsequently,the backend program of the platform implements time section homogenization and extracts effective information from the point table,and then completes data check through a direct check algorithm.Through experimental check of the actual point table of a certain main and plant station,a direct check algorithm with higher accuracy and speed than cyclic redundancy check was selected to check the effective information after point table processing.The simulation check results show that the proposed online automatic check technology for power remote control transmission data not only achieves closed-loop automatic check process,greatly improving check efficiency,but also achieves end-to-end check of remote control transmission data,greatly improving the timeliness and reliability of check results.
