Embodiment 1

[0033] refer to figure 1 , figure 1 It shows the implementation flow of the substation pressure plate anti-misoperation method provided by Embodiment 1 of the present invention, wherein the pressure plate includes a soft pressure plate and a hard pressure plate, and the method is described in detail as follows:

[0034] S101: Receive the status information of the soft press plate sent by the monitoring system and the status information of the hard press plate sent by the intelligent anti-malfunction device.

[0035] Among them, the soft pressure plate refers to the switching on and off of a certain function of the software system, such as switching on and off a certain protection and control function. The change of the throwing and withdrawing state of the soft pressure plate is usually realized by modifying the software control word protected by the microcomputer. The monitoring system can monitor the state of the soft pressing plate, and the device obtains the state inform...

Embodiment 2

[0049] refer to figure 2 , figure 2 It shows the implementation process of the method for preventing misoperation of substation pressure plate provided by the second embodiment of the present invention. On the basis of the foregoing embodiments, the embodiments of the present invention are described in detail as follows:

[0050] S201: Receive the soft platen status information sent by the monitoring system through a standard interface communication protocol.

[0051] Specifically, the device establishes a communication connection with the monitoring system through the RS232 interface, and according to the communication protocol of the monitoring system, a corresponding communication protocol is designed to realize data transmission.

[0052] S202: Receive the hard press plate state information collected by the press plate state collector on each panel cabinet and acquired by the hard press plate state sensing module on the screen cabinet sent by the intelligent error prev...

Embodiment 3

[0065] refer to image 3 , image 3 It shows the implementation flow of the method for preventing misoperation of the substation pressure plate provided by the third embodiment of the present invention. On the basis of the foregoing embodiments, the embodiments of the present invention are described in detail as follows:

[0066] Steps S301 to S304 are consistent with the above S101 to S104, please refer to the relevant description of S101 to S104 for specific content, and will not be repeated here.

[0067] S305: After determining that the simulation rehearsal is successful, send the soft press plate operation ticket to the monitoring system, so that the monitoring system changes the soft press plate throw-in and withdrawal status according to the soft press plate operation ticket.

[0068] Specifically, the device establishes a communication connection with the monitoring system through the RS232 interface, and according to the communication protocol of the monitoring syst...

Abstract

The invention is suitable for the technical field of electric power equipment and discloses a transformer station pressboard anti-error operation method and device. The method comprises steps that thesoft pressboard state information sent by a monitoring system and the hard pressboard state information sent by an intelligent anti-error device are received; the pressboard anti-error logic information is generated according to the soft pressboard state information, the hard pressboard state information and the pre-stored anti-error logic information of primary equipment; an operation bill is generated according to the pressboard anti-error logic information; simulation rehearsal is carried out according to the operation bill, and whether simulation rehearsal succeeds is determined; after simulation rehearsal succeeds, the operation bill is sent to a corresponding pressboard control module to make the pressboard control module control a pressboard according to the operation bill for carrying out switching operation. The method is advantaged in that real-time pressboard state monitoring can be realized, the pressboard error switching phenomenon can be prevented, pressboard managementefficiency is improved, and safe operation of the power grid is guaranteed.

Description

technical field [0001] The invention belongs to the technical field of electric power equipment, and in particular relates to a method and device for preventing misoperation of a substation pressure plate. Background technique [0002] The protection pressure plate includes a function pressure plate and an outlet pressure plate. The function pressure plate is used for switching on and off of the protection function or the automatic control function, and the outlet pressure plate is used for the tripping of the circuit breaker or the start of other protection functions. In the case that the primary and secondary equipment of the power system have been intelligentized to varying degrees, the intelligent management and anti-misoperation of the pressure plate of conventional substations and smart substations are still in a blind spot, and there are many potential safety hazards. [0003] At present, the substation error prevention system is mainly aimed at the primary equipment,...
