基于强化自然语言理解的变电站一键顺控自动校核研究

Control Automatic Calibration of Substation Based on Enhanced Natural Language Processing

随着现代化设备管理体系要求的不断健全落地,一键顺控技术作为电网基层运维一线降本减负,探索数字化改革和“两个替代”建设的重要抓手,如何安全有序地确保一键顺控技术应用上线是目前主网运检业务的瓶颈。一键顺控是按国网公司“改造一个,验收一个,上线一个”的原则进行,而传统一键顺控验收最关键的环节是顺控操作票的验收,主要基于“监控系统一键下发指令,人工检查设备实际变位”相结合的模式进行,存在验收盲区、验收效率低、隐患排查不彻底、带电设备无法验收等痛点。为提升变电站一键顺控验收质量和效率,提出基于专家语义识别算法进行一键顺控操作票和运维典型操作票语义识别,对一键顺控改造的变电站全间隔、全数据的“1对1”遍历校核,实现在精确匹配下的查错、查漏和纠错,进而实现顺控操作票不停电、离线、智能、高效化验收,确保一键顺控应用后电网的安全稳定运行。

With the modernization of equipment management system requirements continue to sound landing,a key to the control technology as the grid grass-roots operation and maintenance of the first line of cost reduction,explore the digital reform and the"two alternatives"construction of an important hand,how to safely and orderly ensure that the application of a key to the control technology on-line is the bottleneck of today′s main network operation and inspection business.At present,one-key sequence control is in accordance with the State Grid Corporation′s principle of"one transformation,one acceptance,one on-line",and the most critical link in the acceptance of traditional one-key sequence control is the acceptance of the smooth control operation ticket,which is based on the combination of the mode of"one-key command from the monitoring system and manual inspection of the actual equipment displacement".The most critical part of traditional one-key sequence control acceptance is the acceptance of the operation ticket,which is mainly based on the combination of"one-key command from the monitoring system and manual checking of the actual transformer position of the equipment".Therefore,in order to improve the quality and efficiency of acceptance of one-key sequence control of substation,this paper proposes to carry out semantic recognition of one-key sequence control operation ticket and operation and maintenance typical operation ticket based on expert semantic recognition algorithm,and"1 to 1"traversing verification of the whole interval and data of the substation transformed by one-key sequence control,thus realizing the error checking,omission checking and error correcting under the precise matching,and achieving the goal of"one-key sequence control operation ticket without power outage".It realizes the non-stop,offline,intelligent and efficient acceptance of smooth control operation tickets,ensuring the safe and stable operation of the power grid after the application of one-key sequence control.
