500kV变电站二次安措移动管控平台的研究与实践

Research and practice of mobile control platform for secondary safety measures in 500kV substation

随着电网技术的不断发展,由于500kV变电站二次设备智能化程度与二次设备新老程度的不同,造成现场二次回路情况复杂,导致二次检修作业安措票编制困难,易出错,对电网安全运行构成较大威胁。针对上述问题,本文完善了检修作业二次安措票全过程管控流程,设计并开发了500kV变电站二次安措移动管控平台,覆盖500kV智能变电站和常规变电站,由后台软件自动生成检修作业的二次安措票,由移动终端完成二次安措票的开具、审核、签发、执行、恢复、归档和查询等环节,实现了二次安措票全生命周期的在线管控。现场实际应用证明,该管控平台能够保证二次安措的准确性,提高检修工作效率,降低人员因技能水平不足而造成的安全风险,为实现运检智能化进行了有益的探索并积累了实践经验。

With the continuous development of power grid technology,the intelligent degree and the age of secondary equipment in 500kV substation is different,which leads to complex secondary circuit conditions,difficult preparation of security measures for secondary maintenance,easy to make mistakes,and poses a great threat to the safe operation of power grid.According to the above problem,this paper improves the maintenance secondary safety measures full process control,designs a mobile control platform for secondary safety measures in 500kV substation which covering 500kV smart substation and conventional substation.Secondary safety measures can be generated by the backend software automatically,issuance,review,execution,recovery,filing,inquiry and other links of secondary safety measures could be completed by mobile terminals,realized the full life cycle of secondary safety measures online control.The field application proves that the control platform can ensure the accuracy of the secondary safety measures,improve the maintenance efficiency,reduce the safety risk caused by the insufficient skill level of personnel,and make beneficial exploration and accumulate practical experience for the realization of intelligent operation and inspection.
