Problems solved by technology

[0003] However, the joint debugging of the control information of the existing telecontrol devices mainly relies on manual real-time communication between the master station and the factory station, that is, the information received by the master station and the information received by the master station are manually connected point by point The factory station sends information for proofreading, and a lot of work is repeated
This method has a single technical means, lacks effective debugging tools, and has a low degree of automation. It requires a lot of manpower and time, resulting in a long debugging cycle before the smart substation project is put into operation.

[0029] Reference figure 2 The flow chart of an intelligent verification method for substation based on IED simulation of the whole station is shown. The method specifically includes the following steps:

[0030] Step S201: Obtain the SCD file to which the entire station belongs.

[0031] Among them, SCD is the abbreviation of substation configuration description in the substation IEC61850 standard, that is, the whole station system configuration file.

[0032] Generally speaking, SCD files are pre-configured.

[0033] Step S202: Analyze all remote signaling signals in the full-site IED device model carried in the SCD file.

[0034] Among them, the SCD file is written in XML language.

[0035] As an implementation manner, step S202 includes: parsing all remote signaling signals in the full-site IED device model carried in the SCD file based on the Document Object Model (DOM).

[0036] In the above implementation process, through the DOM interface, the application can access any part of th...

Abstract

The embodiment of the invention provides a transformer substation intelligent checking method and device based on whole-station IED simulation. The method comprises the steps of obtaining an SCD fileto which a whole station belongs; analyzing all remote signaling signals in the full-station IED device model carried by the SCD file; automatically turning and shifting each remote signaling signal in sequence through an MMS protocol to be sent to a telecontrol device; receiving an IEC104 message returned by the telecontrol device based on the remote signaling signal; analyzing the IEC104 messageto obtain a forwarding table of the telecontrol device; loading a regulation and control information table; and based on the regulation and control information table, an MMS sending record file, an IED 104 message receiving record file and a historical event record file, generating a telecontrol device check report. According to the method and the device, a manual checking mode in the prior art can be overcome, the labor cost is effectively saved, the checking time is shortened, the checking efficiency is improved, and the debugging period before transformer substation engineering commissioning can be effectively shortened.

Description

Technical field [0001] This application relates to the field of power grid application technology, and in particular to a method and device for substation intelligent verification based on IED simulation of the whole station. Background technique [0002] At present, conventional substation and intelligent substation monitoring systems need to collect a large amount of equipment operating status information, including primary equipment status data, secondary equipment status data and auxiliary equipment data. These data are sent to the station control layer equipment by means of MMS (Manufacturing Message Specification) messages at the equal interval layer IED (Intelligent Electronic Device) of the monitoring and control device of the protection device, such as monitoring host and remote control device. . The substation data communication gateway machine, that is, the remote control device, as an important station control level equipment, communicates with the lower level equipm...
