Detailed Description

Reference will now be made in detail to embodiments, examples of which are illustrated in the accompanying drawings. When the following description refers to the accompanying drawings, like numbers in different drawings represent the same or similar elements unless otherwise indicated. The embodiments described in the following examples do not represent all embodiments consistent with the present application. But merely as exemplifications of systems and methods consistent with certain aspects of the application, as recited in the claims.

Referring to fig. 1, a management system for temporary ground wires for management of ground wires of electrical plant equipment, comprising:

an electric monitoring and managing system is provided,

the electrical monitoring management system is used for monitoring the loop parameters of the electrical equipment in real time and sending a position division signal of the on-off state of the electrical equipment; for example, an ECS electrical equipment management system is a system that separates the electrical components in the system for professional management to implement comprehensive functions of protection, measurement, control, analysis and the like of a low-voltage electrical system in service power, belongs to the prior art, and is not described herein again, and has the functions of coordinating the synchronous development of thermal control and electrical automation of a power plant, comprehensively improving the automation level and the service control management level of the power plant, and ensuring the safety and reliability of the operation of the power plant;

an electronic operation ticket system electrically connected with the electric monitoring management system,

the method can be used for manufacturing a switching operation ticket of the electric equipment suspension grounding wire and sending the switching operation ticket. The operation ticket refers to the written basis for performing electrical operation in the power system, and comprises a scheduling instruction ticket and a power transformation operation ticket, and main measures for preventing misoperation, misoperation of pulling, misoperation of closing, on-load pulling, on-disconnecting switch, on-grounding switch and the like are taken. An electronic operation ticket system, for example, an SIS system in the prior art, reads a real-time state of an electrical device of an electrical monitoring management system, performs operation by using a graphical operation interface, and makes and displays an operation ticket; an operation ticket, for example, a switching operation ticket. The electrical equipment is divided into three states of operation, standby and maintenance, the process of converting one state of the equipment into the other state is called switching, and the operation is called switching operation;

the host computer of earth connection management cabinet can receive branch position signal and switching operation ticket, receives the two letter back and carries out five-prevention logic judgement to the electrical equipment that switching operation ticket corresponds, and satisfies: through five-prevention logic authentication, an unlocking instruction is sent to the grounding wire cabinet, and an operation technician replaces or temporarily suspends a power connection wire;

the ground wire management cabinet is an intelligent management cabinet in the prior art and can receive an unlocking instruction and unlock a corresponding ground wire; and the unlocked state of the ground wire after being hung again is transmitted to an upper computer for display through a ground wire management cabinet.

The working principle is as follows:

the ground wire grounding wire simulation system mainly improves a simulation link of manual operation, extracts the state of a power switch from the existing ECS system and extracts corresponding relevant information of a grounding wire from the operation information of the existing operation ticket to replace the manual simulation link, and unlocks and locks the corresponding grounding wire in the grounding wire management cabinet after operation authentication is finished. The state of the switch is extracted from the ECS system of the power plant, and the related information of the suspension grounding wire is extracted from the existing electronic operation ticket system. The ground wire management upper computer extracts the state of the switch and the position information of the suspended ground wire from the ground wire management upper computer to carry out five-prevention logic authentication, and corresponding ground wires are unlocked according to logic requirements.
