Combined with the state of security and stability control management system (SCMS) and the needs of large power grid dispatching control technology,this paper analyzes the deficiencies of existing SCMS,and proposes the technical scheme of a new integration SCMS based on smart grid dispatching control system platform.A software system contains collection-monitoring-alarm-warning-decision-control is designed.To solve the problem of transition between the new SCMS and service SCMS,the paper propose a project application method of the security and stability control device connect two SCMS with different protocols.A control strategy analysis service based on the class definition and operation factor model of hierarchical security and stability control system and control strategy is developed.It will support strategy analysis service for other application modules thus as Dynamic Security Analysis (DSA).Based on the"horizontal isolation"safety protection strategy,SCMS establishes the connection with the work ticket management system and off-line analysis computation system in management information area,which achieves the setting value list closed loop management and support data for transmission section real time limit calculation and control strategy adaptive check.Finally,the application of the system in Anhui power grid is introduced.
