Combined with the business requirements ofintelligent operation and maintenance under the mode of "centralizedcontrol station + unattended substation + equipment master system" ofpower grid company, Fully inheriting the construction experience andachievements of the existing centralized control and error prevention system,through key technologies such as "PMS interworking, remote control(sequence control) constraint, operation right control and informationmonitoring", the problems such as low ticket preparation efficiency of centralizedcontrol master station, lack of security constraint in remote control /sequence control operation, incomplete control information and lack of businesscollaboration among systems are solved, which supports the new mode ofsubstation operation and maintenance management and improves the regional powerefficiency Network security management and control level.

ADVANTAGE

Centralized monitoring

It can monitor and check the status of secondary equipment, grounding wire, tools and instruments, unlocking key, etc. in the error prevention workstation of the centralized control station.
Remote control / sequence control

Topology error proofing (inter station) and logic formula error proofing (logic formula is imported from station end) are used to check the remote control / sequence control operation initiated by centralized control station.
Switching error prevention

The topology error proofing technology is used to realize the inter station tie line error proofing and locking function.
Exclusive operation right

Under the cooperation of master station and substation, the unique operation right control of equipment is realized among multi task, multi team and multi operation location.
Full coverage

When the centralized control master station simulates the operation, the system will judge the status of the relevant primary and secondary equipment, so as to realize the full error prevention.
PMS interworking

Interact with PMS system to realize the synchronization of billing and simulation verification and the extraction of work ticket information, break through the information barrier and improve work efficiency.
Prepare order in advance

The operation and maintenance team can prepare order in advance, and can view the substation equipment information remotely. According to the dispatching order sent by PMS, the operation order can be generated.
