Example Embodiment

[0018] The present invention will be further described below in conjunction with specific embodiments:

[0019] Analyze the SCD file, filter the GOOSE control block and the MMS report control block, extract the GOOSE subnet configuration information and MMS subnet configuration information related to the alarm message, and establish the alarm message feature database.

[0020] The GOOSE subnet configuration information specifically refers to the access point name and IED device name contained in each ConnectedAP node in the SubNetwork node of the GOOSE subnet, and the control block name, logical instance name, MAC address, APPID, APPID, MinTime and MaxTime, etc.; in addition, GOOSE subnet configuration information also includes DatSet and FCDA information about GOOSE message transmission in the IED node. The MMS subnet configuration information specifically refers to the access point name and IED device name contained in each ConnectedAP node in the SubNetwork node of the MMS subne...

Abstract

The invention discloses an intelligent transformer station secondary equipment state data warning displaying method which comprises the following steps: parsing an SCD file; extracting GOOSE subnet configuration information and MMS subnet configuration information related to warning messages; parsing GOOSE messages and MMS messages matched with the configuration information; extracting APPID, goID, DatSet and the like in the GOOSE messages; extracting DatSet, DataRef and Value in the MMS messages; taking the APPID, goID, DatSet extracted from the GOOSE messages and the DatSet and DataRef extracted from the MMS messages as input for analysis; judging whether the GOOSE messages or the MMS messages are abnormal and require warning or not; conducting grading warning displaying according to a pre-arranged warning grading rule if the GOOSE messages or the MMS messages are abnormal and require warning. According to the intelligent transformer station secondary equipment state data warning displaying method, the warning messages can be graded for displaying, so that on-site operating personnel can visually and accurately know the warning information, and quickly locate and handle failures according to the serious degree of the warning; the operation efficiency is improved; the joint debugging period of a project is shortened.

Description

technical field [0001] The invention relates to the technical field of status monitoring of smart substations, in particular to a method for displaying status data alarms of secondary equipment of smart substations. Background technique [0002] Realizing panoramic data collection and information sharing of intelligent substation based on network is an important feature of intelligent substation. Substituting the network for secondary cables is an important means of intelligent process layer, and the security and stability of the network are closely related to the safe operation of the substation. The network communication system of smart substation is very complex, and the workload of its operation and maintenance is very heavy. In the existing situation, the smart substation is equipped with a network analyzer, and the abnormal alarm and fault diagnosis of the communication network rely on the playback and alarm functions of the network analyzer, and the network status mo...
