Description
Technical Field
The application relates to the technical field of power management, in particular to a distribution network error-prevention management system and method of an overall process closed loop.
Background
At present, the current situation of distribution network equipment and error prevention management is as follows:
the distribution network switching-off equipment has problems. The error locking prevention between cabinets is absent. For the interconnection of the two or more ring main units, namely, when the operation of different cabinet bodies is executed, logic locking is not performed, and if the operation sequence is improper, accidents such as the disconnection of a power supply side switch and the false connection of a load side ground knife can be caused. The old cabinet type device is free of error prevention. The old switch cabinet with early partial production time has no error preventing device inside or has design defects, which easily causes the loss of error locking preventing function and increases the operation risk. The live display has no latch-up function. The existing high-voltage live display of the distribution network equipment has only a prompting function, does not have forced locking output, and has a severe misoperation accident of a live ground closing knife.
The distribution network is prevented from being mismanaged and has loopholes. The remote control operation of the distribution network has no misjudgment of an anti-mishandling system, is easy to cause mishandling accidents and causes harm to equipment and personal safety. The existing operation system has low tolerance to personnel, and if the name and the number of the operation equipment are not carefully checked, the risk of wrong running interval and wrong operation equipment exists. The anti-misoperation lockset and the key are disordered in management, such as the same key, easy rust and jamming, low lockset theft resistance, high key management difficulty and the like, and the safety literacy and skill level dependence on field personnel are high. The operation is not refined, and the execution efficiency is low. The operation command of the distribution network is issued in a task form, is not refined to an operation step, and cannot be completed by division. For one operation task, operators often need to go to and fro between a plurality of sites to perform operations of different steps, so that time is wasted and labor intensity is increased.
When a worker executes switching operation according to the operation ticket, the worker can encounter various switches, and the worker is careless and easy to operate errors. For example, when a pole has a circuit breaker and a disconnector, the ticket indicates that the circuit breaker should be opened and then the disconnector should be opened. Because the existing one brake pull rod is suitable for both the circuit breaker and the isolating switch, when a worker makes a surprise, the isolating switch is firstly opened by the brake pull rod to open the circuit breaker, so that an operation error occurs.
In addition, the anti-misoperation measures of the distribution network have the problems that the original effect of the anti-misoperation management means is poor, the equipment state depends on manual input, the operation ticket establishment depends on personnel level and the like. The existence of the problems increases the labor intensity of distribution network operators, influences the working efficiency and also provides hidden danger for misoperation of the distribution network. This forces the rapid construction of the distribution network to accommodate the ever-evolving needs of society. Through hundred-degree search, patent inquiry, network paper inquiry and manufacturer inquiry, a software and hardware device which can perform network topology verification, automatic ticket issuing and five-prevention locking functions on a switch cabinet and column equipment is not found in the market. With the development and maturity of the internet of things technology, the current situation of distribution network operation management can be fundamentally improved by utilizing the intelligent technology to realize power distribution misoperation prevention. Therefore, through sensing and controlling the state and the operation process of the distribution network equipment, risks brought by misscheduling, misoperations and the like are effectively avoided, and a practical intelligent misoperation prevention system capable of comprehensively sensing the safe operation state of the equipment is necessary to be established.
