基于变电站二次系统的在线监测设计优化OA

With the improvement of substation's intelligence,the reliability of secondary system has become a decisive factor affecting the safe operation of substation.At present,there are some problems exist in on-line monitoring of substation secondary system,such as incomplete function,disunity of scheme and main station system.In order to meet the urgent need of on-line monitoring of secondary system in operation,and realize the unification of different on-line monitoring technology schemes,this paper presents an optimization design technology.Through the introduction of the whole system framework and information collection methods,together with the demonstration of the typical design schemes,the paper puts forward the application and implementation suggestions of the secondary system online monitoring with technical and economic coordination.In terms of power grid operation and maintenance,the secondary system optimization can effectively improve the management level of secondary equipment.In terms of power grid security,with the help of comprehensive online monitoring of the secondary system,the safe and stable operation of the power grid can be effectively guaranteed,so as to cope with the complex operation of the power grid under the new power system and realize the construction of a new digital smart grid.
