Abstract
A kind of distribution protection module failure monitoring method, includes the following steps: step 1: periodically forming situation id signal after protective module movement and is sent to monitoring modular；Step 2: comparing whether id signal changes, step 3: after monitoring modular receives situation id signal, and being compared with the situation id signal that last time receives；Step 4: after relatively; if id signal is consistent twice; monitoring modular parses the data packet after id signal; and the information in updated data package is corresponding protective module last state; if id signal is inconsistent twice; the state of protective module is updated to last situation id signal, while monitoring modular carries out inspection to protective module.Protective module of the invention combines active upload status information to monitoring modular and passive acquisition to monitoring modular, change all be in the past monitoring modular acquisition mode, improve the reliability of protective module, reduce power grid and equipment breakdown.
Description
Technical field
The present invention relates to Relay Protection Technology in Power System fields, are specifically related to a kind of distribution protection module monitors side
Method.
Background technique
Integrated automation converting station is respectively mounted a protective module to every route or main transformer, measure and control device, due to protection
Outmoded, individual protective modules meeting failures or the crash of module, but these modules data show, and operation maintenance personnel is difficult when making an inspection tour
It was found that this defect.The protective module of substation, cannot once crash or failure, protection normally can not alert or issue alarm signal
The requirement for guaranteeing reliability, may cause power grid and equipment breakdown.
Summary of the invention
In order to solve the above technical problems, the present invention provides a kind of distribution protection module monitors method.
The object of the present invention is achieved in the following manner:
A kind of distribution protection module failure monitoring method, including the protective module being connect with measure and control device, the guarantor
Shield module failure monitoring method includes the following steps:
Step 1: situation id signal is periodically formed after protective module movement and is sent to monitoring modular；
Step 2: comparing whether id signal changes, and protective module has movement, and id signal is " 1 ", if protective module
Not operating, id signal is " 0 "；
Step 3: after monitoring modular receives situation id signal, and the situation id signal received with last time is compared
Compared with；
Step 4: after relatively, if id signal is consistent twice, monitoring modular parses the data packet after id signal, and
Information in updated data package is corresponding protective module last state, if id signal is inconsistent twice, by protective module
State is updated to last situation id signal, while monitoring modular carries out inspection to protective module, if protective module is no different
Often, then situation id signal is continuously formed, if there is abnormal, protective module failure, cutting power control circuit power supply.
The situation id signal includes id signal and data packet.
It include the monitoring information of protective module in the data packet.
Protective module of the invention mutually ties active upload status information to monitoring modular with passive acquisition to monitoring modular
Close, change in the past be all monitoring modular acquisition mode, improve the reliability of protective module, reduce power grid and equipment thing
Therefore.
Detailed description of the invention
Fig. 1 is flow chart of the invention.
Specific embodiment
To further illustrate the technical scheme of the present invention below with reference to the accompanying drawings and specific embodiments.
A kind of distribution protection module failure monitoring method, including the protective module being connect with measure and control device, the guarantor
Shield module failure monitoring method includes the following steps:
Step 1: situation id signal is periodically formed after protective module movement and is sent to monitoring modular；
Step 2: comparing whether id signal changes, and protective module has movement, and id signal is " 1 ", if protective module
Not operating, id signal is " 0 "；
Step 3: after monitoring modular receives situation id signal, and the situation id signal received with last time is compared
Compared with；
Step 4: after relatively, if id signal is consistent twice, monitoring modular parses the data packet after id signal, and
Information in updated data package is corresponding protective module last state, if id signal is inconsistent twice, by protective module
State is updated to last situation id signal, while monitoring modular carries out inspection to protective module, if protective module is no different
Often, then situation id signal is continuously formed, if there is abnormal, protective module failure, cutting power control circuit power supply.
The situation id signal includes id signal and data packet.
It include the monitoring information of protective module in the data packet.
What has been described above is only a preferred embodiment of the present invention, it is noted that for those skilled in the art,
Without depart from that overall concept of the invention, several changes and improvements can also be made, these also should be considered as of the invention
Protection scope.
Claims (3)
1. a kind of distribution protection module failure monitoring method, including the protective module being connect with measure and control device, it is characterised in that:
The protective module fault monitoring method includes the following steps:
Step 1: situation id signal is periodically formed after protective module movement and is sent to monitoring modular；
Step 2: comparing whether id signal changes, and protective module has movement, and id signal is " 1 ", if protective module is not moved
Make, id signal is " 0 "；
Step 3: it after monitoring modular receives situation id signal, and is compared with the situation id signal that last time receives；
Step 4: after relatively, if id signal is consistent twice, monitoring modular parses the data packet after id signal, and updates
Information in data packet is corresponding protective module last state, if id signal is inconsistent twice, by the state of protective module
It is updated to last situation id signal, while monitoring modular carries out inspection to protective module, if protective module is without exception,
Situation id signal is continuously formed, if there is abnormal, protective module failure, cutting power control circuit power supply.
2. distribution protection module failure monitoring method as described in claim 1, it is characterised in that: the situation identifies letter
Number include id signal and data packet.
