With the electricity market changing in modes and the proportion of new energy gradually increased,it is necessary to further verify whether the original offline strategy can meet the real-time operation of the power grid.Firstly,the software and hardware architecture of the online checking system for stability control strategy is studied,and a scalable and flexible distributed architecture is adopted to facilitate the sharing and synchronization of model and computational data.The external interface of the online checking system for stability control strategy is studied to obtain the duty strategy information from the security master station,to get the real-time operation mode information of the power grid from the dispatching master station,and to acquire the parameter information of power grid components from the offline analysis system.The overall calculation flow of the online checking of the strategy is studied;the system parses the duty strategy file,and then calls the electrical topology service program and the name matching program to complete the grid parameter extraction and real-time calculation topology generation;service program is computed and subsequently,the stability of the power grid after the strategy action in real-time mode is analyzed according to the expected fault in the current duty strategy,with the unstable results sent to the dispatching master station through the intelligent alarm interface,so as to provide auxiliary decision-making for dispatchers.
