Research on Rapid Point-to-Point Method of Secondary System of Smart Substation

Currently, the signal point-to-point of secondary equipment in substations is still in manual mode, which has the characteristics of large workload and low efficiency. This article proposes a fast point-to-point method for secondary equipment signals in intelligent substations. The method simulates MMS message data input into the remote control system at the station control layer, maintains the connection between the remote control system terminal and the control center, and automatically sends the device action information to the control background. The simulated message data is compared with the control background information to complete signal point-to-point. Finally, through on-site practical case testing, it was shown that this method can accurately, quickly, and effectively complete signal point-to-point in the station, saving a lot of time and manpower, and improving the efficiency of intelligent substation debugging work.
