Description
Technical field
The present invention relates to a kind of complete adjustment method of breaker protection function.
Background technology
For in transformer station, chopper is primary equipment, and it is arranged between Generation Side and electricity consumption side, is for control line
The visual plant of road transmission or not, is generally located on open air；Secondary device refers to relevant parameter when being energized by monitoring breaker
(electric current and voltage), reaches to pass by online and flows or the equipment of automatic tripping chopper when short circuit, mainly include measure and control device
And protection device, the master control being generally located on transformer station is indoor.
The information (observing and controlling information and protection act information) reflected when chopper is because of fault trip is electric power system dispatching personnel
Carrying out the important evidence of accident analysis, observing and controlling information spinner to include switching separating brake information, switch combined floodgate information and control loop template
Information, protection act information spinner overcurrent tripping to be included information, short circuit tripping operation information and reclosing information；Inaccurate or incorrect
Circuit breaker failure information dispatcher can be caused to judge by accident, send false command, cause larger range of power outage.
In transformer station, protection act information is sent message, then the monitoring being transferred in transformer station by network by protection device
Computer；Switch point, closing a floodgate and the information such as control loop template sends message by measure and control device, the interior network that is transferred to stand is sent out again
Deliver to the monitoring computer in transformer station.
Conventional adjustment method: individually carry out the separating brake of chopper, combined floodgate, protection act, reclosing, control loop template
Debugging etc. function.
This kind of adjustment method can not judge the sequence of movement of various information during circuit breaker trip.Particularly in transformer station
Under GPS correction device abnormal conditions, during the Time Inconsistency of measure and control device in transformer station and protection device, chopper can be caused
The various information sequence error of course of action, causes dispatcher to judge by accident when accident analysis, and this situation is a plurality of in transformer station
The impact that dispatcher carries out when tripping in the line-breaker short time accident analysis simultaneously is the most serious.
Summary of the invention
The present invention is to solve the problems referred to above that prior art exists, it is provided that a kind of complete adjustment method of breaker protection function.
The technical solution of the present invention is:
The complete adjustment method of breaker protection function, it is characterized in that:
1, by protection act information and switch separating brake information through logical "and" door, composite signal is entitled, and " this chopper is responsible for line
Road has an accident "；
2, set the switch separating brake information of chopper, switch combined floodgate information and control loop template information to be sent by measure and control device；Set
Overcurrent tripping information, short circuit tripping operation information and reclosing action message are sent by protection device；
3, by chopper by open position to closing position or by the transient state in the middle of closing position to open position, the most neither dividing
Gate position is not defined as control loop template state in the state of closing position, when chopper is in this state, and measure and control device
Send " control loop template " information；
4, using chopper run into transient fault tripping again by protection device start coincidence function whole process as reference, sequentially
Formulating the observing and controlling information that reflected and protection act information, this order is normal sequence: this chopper be responsible for circuit have an accident,
Protection act, switch separating brake, control loop template, reclosing action, switch close a floodgate；
5, run into the environment of above-mentioned transient fault with electric current voltage analog testing stand mimic-disconnecting switch, measure and control device and protection device send
The information that chopper is reflected, is transferred to monitor computer, and the information reflected by monitoring computer recording by network in station
Before and after order；
If before and after 6 information reflected by monitoring computer recording, order is consistent with normal sequence, it is believed that chopper possesses power transmission bar
Part, can carry out power transmission；When difference, before and after the information that will reflect, order is compared with normal sequence；
If 7 lack " this chopper is responsible for circuit and is had an accident " information, then check the synthesis condition of supervisory control of substation computer；
If 8 lack " protection act " information, then checked that the corresponding function of protection device is the most just in transformer station by field maintenance person
Often；
If 9 lack " switch separating brake " information, then checked that the corresponding function of measure and control device is the most just in transformer station by field maintenance person
Often, check that whether chopper is in relevant position；
If 10 lack " control loop template " information, then checked that transformer station's inner breaker is the most normal and becomes by field maintenance person
In power station, the corresponding function of measure and control device is the most normal；
If 11 lack " reclosing action " information, then checked that the corresponding function of protection device is in transformer station by field maintenance person
No normally；
If 12 lacking " switch closes a floodgate " information, then checked in transformer station the corresponding function of measure and control device whether by field maintenance person
Normally, check that whether chopper is in relevant position；
If the information order reflected during 13 breaker actuation is inconsistent with normal sequence, then checked by field maintenance person
The time of measure and control device and protection device whether strict conformance in transformer station, when checking the school in transformer station, equipment is the most working properly；
If during 14 is whole, information is without lacking and identical with normal sequence, then explanation circuit-breaker status is normal, meets power transmission bar
Part.
The invention has the beneficial effects as follows: present invention basically comprises the full detail that chopper is likely to occur under accident, monitoring is complete
Face, can carry out rapidly fault location, and accurate positioning, available existing current/voltage simulator stand, it is not necessary to additionally set
Standby investment, brings great convenience to dispatcher, enables dispatcher accurately grasp circuit abnormal information in the state of accident,
And the most correctly process, reduce the loss of supply.
Accompanying drawing explanation
Fig. 1 is the system diagram of the present invention.
Detailed description of the invention
This complete adjustment method of breaker protection function, it has main steps that:
1, using chopper run into transient fault tripping again by protection device start coincidence function whole process as reference, sequentially
Formulating the observing and controlling information and protection act information reflected, this order is normal sequence (being shown in Table 1): this chopper is responsible for circuit
Have an accident, protection act, switch separating brake, control loop template, reclosing action, switch close a floodgate；
2, run into the environment of above-mentioned transient fault with electric current voltage test platform mimic-disconnecting switch, measure and control device and protection device send open circuit
The information that device is reflected, before being transferred to monitor computer, and the information reflected by monitoring computer recording by network in station
Rear order；
If before and after 3 information reflected by monitoring computer recording, order is consistent with normal sequence, it is believed that chopper possesses power transmission bar
Part, can carry out power transmission；When difference, before and after the information that will reflect, order is compared with normal sequence, it is judged that stand
Which device interior is abnormal.
