The invention relates to the field of automation of power systems, in particular to a substation secondary system dynamic reconfiguration device and a reconfiguration method thereof. According to the device, a standby reconfiguration device is applied to a substation lead-in interval and a main transformer interval. The device comprises station level equipment, process level equipment, interval level equipment and communication equipment, wherein the station level equipment is respectively connected with a station level network and a process level network through the communication equipment, the process level equipment is connected with the process level network through the communication equipment, information interaction is respectively performed between the standby reconfiguration device of the interval level equipment and a secondary equipment monitoring and reconfiguration management host of the station level equipment as well as the process level equipment, and the DL / T860 standard is followed during the information interaction. By using the software and assembly technique and the standardized development technique for realizing secondary equipment functions in the device, dynamic reconfiguration and quick recovery of specific functions are realized by applying the standby reconfiguration device under the condition that partial secondary equipment functions fail, so as to improve the robustness of the whole system.
Description
technical field [0001] The invention relates to the field of power system automation, and relates to a device and method for manufacturing power system automation equipment / products, in particular to a dynamic reconfiguration device and a reconfiguration method for a substation secondary system. Background technique [0002] In the existing intelligent substation, the sampling link of the secondary device and the input and output link of the switching value are realized by the merging unit and the intelligent terminal respectively. The information interaction between the merging unit, the intelligent terminal and other equipment in the station and the secondary device is completely completed by means of communication. Through the standardization and networking of information exchange, the information in the station has been highly shared. In addition, since the secondary device basically has no other interfaces except the network interface and the power supply interface, th...
