Abstract：At present, the standalone mode of anti-maloperation system configured in the substation cannot fully meet the reliability requirements of the integrated regulation and control operation mode, In order to solve this problem, we designed an anti-maloperation dual operation mode, including the adjustment of system application architecture, the optimization of software module, It ensures the realization of the redundancy configuration of the double computers via the technical processing of anti-maloperation dual machine virtual remote signal synchronization, locking information synchronization, and sole operation right, improving the reliability of the whole system.
