The uniform and operational function specification of batch remote control based on different supervisory control and data acquisition（SCADA） systems is described. The realization method in actual engineering is proposed. The proposed function is applied in Shanghai Power Grid，which shows that the function can extend the application of SCADA system and increase the level of SCADA system practicability. It provides effective technical measures for dispatchers to cut load in case of over supplying and emergent load curtailing. It can also improve the efficiency of switching load between different dispatching regions. As an expanding SCADA system application， the proposed function is worth spreading.
