Conventional substation anti-error solution
This program provides a real-time and comprehensive substation microcomputer anti-error system solution, introducing UT-Net micro-power wireless network, real-time detection and tracking of ground wires, mandatory electrical inspection lockout, and platen status Technologies such as acquisition and error prevention can realize real-time monitoring of the whole process of switching operation, real-time judgment of error prevention logic, real-time positioning of equipment status, forced locking of local/remote operation, dual-network multi-mode operation, etc. The system solves the problems of disconnection of the operation information interaction of the offline error prevention system, imperfect locking means, and the inability to guarantee the real-time operation of the operation. It is a technical means to fully guarantee the safety, correctness, reliability, and real-time operation of the operation.
system structure
The system is divided into three layers: the station control layer, the interval layer and the process layer: the
station control layer is composed of the anti-error host, which completes the simulation of the operation ticket, the judgment of the anti-error logic, the collection of real-time status and other functions. The computer or the process layer can be selected. Analog screen.
The compartment layer is composed of a ground wire manager, a remote lock controller, a network controller, a wireless router and a wireless computer key. Complete the unblocking control of the temporary grounding wire, remote control blocking relay, and wireless network communication, unblocking control and other functions.
The process layer is composed of a ground wire detection mechanism, a wireless ground wire, a remote locking relay, a high-voltage live lock device and other lock accessories. It completes the lockout of the temporary ground wire, real-time collection of the wireless ground wire status, forced lockout of electric equipment, and grounding operations Compulsory electrical inspection and mandatory lockout of primary equipment on-site operation.
The system uses reliable wireless network communication, and builds a real-time online network error prevention system in the substation through the wireless network master station, wireless base station, and wireless computer key .
System function The
compulsory anti-misoperation locking is
for different equipment (circuit breaker, isolating switch, grounding switch, network cabinet door, secondary pressure plate, temporary grounding wire, etc.) and different operation methods (remote operation, local operation, grounding operation, inspection Electric operation, etc.), using different locking methods for compulsory anti-misoperation locking.
Anti-error logic real-time judgment
When the operation task is in progress, the anti-error host can make real-time anti-error logic judgment on the current operation according to the change of the device position status, determine whether the operation continues or stop, and use the wireless network to control the operation of the computer key in real time.
Real-time monitoring of the operation process After
the status of the operated equipment and the lock status are collected, they are fed back to the anti-error host through the wireless network, and displayed on the operation interface of the anti-error host in real time. The next operation is opened only after the correct change of the current operating device status is detected, effectively preventing problems such as "empty programs" during operation.
The real-time alignment of equipment status The
computer key can upload the on-site equipment status (including network/cabinet door, temporary grounding wire) to the anti-error host through the UT-NET wireless network accurately and regularly, so as to realize automatic real-time guarantee of the equipment status displayed by the anti-error host Consistent with the equipment status on site. No need to manually set the device status.
Ground wire real-time status detection and error
prevention. The host is connected to the ground wire management system to realize real-time tracking of the ground wire status, and technical measures solve the problems of temporary grounding wire that are prone to wrong connection, wrong disconnection, missed connection, and missed disconnection. , The real-time status of the ground wire participates in the five-prevention judgment, achieving the function of real-time error prevention for ground wire operation.
Compulsory electrical test lockout
The high-voltage live display lockout device in the program has functions such as passive live display, computer key lock interface, etc., which can implement mandatory electrical test lockout to prevent misoperations such as hanging the ground wire when the power is on.
Platen status collection and error
prevention The error - preventing host can collect the real-time cast and return status of the secondary hard platen, and add the operation of the secondary platen to the operation ticket to prevent the occurrence of misoperations such as missed cast, missed return, mistaken cast, and mistaken return.
Interface with video system The
system can interface with video system software to realize the video linkage function of analog operation, switching operation, and alarm.
