Detailed description of the invention
Fig. 1 is logical procedure diagram of the invention.
Specific embodiment
With reference to the accompanying drawing, embodiments of the present invention are illustrated.
As shown in Figure 1, being logical procedure diagram of the invention.A kind of control of the converter transformer cooling system of intelligent patrol detection
Method processed, comprising the following steps:
Electricity operation in step 1, converter transformer cooling system；To guarantee the safe and reliable operation of system, when upper electricity operation,
System uses multiple feed, is powered by 2 road AC:380V and 2 road DC:220V, and be able to achieve manual/auto switching when failure.
Step 2, acquisition converter power transformer terminal case operating status, judge whether converter power transformer puts into operation, if put into operation, if
Start cooling system, control each group cooler, if not putting into operation, going to step 2 repetition judgements；
Herein, the mode of connection of cooling control system is designed as cross box conjugation.I.e. by converter power transformer sheet
All detection signals, status signal, the control signal of body are directly connected in converter power transformer control cabinet by transfer box, by changing
Acquisition, the processing of signal and the sending of control command of rheology control cabinet completion signal.Although this method signal wire is relatively more, connect
Line amount is big, but signal link is clear, does not intersect, and facilitates later maintenance and maintenance.
Step 3 judges cooling system for MANUAL CONTROL mode or automatic control mode, under MANUAL CONTROL mode, utilizes
Button on control cabinet panel manually controls the start and stop of each group cooler, goes to step 3 repetition judgements；It is then gone to step under automatic mode
4.The control model of system is divided into manually and automatically two kinds of control modes, and the selection of manual/auto working method passes through selection
Switch is to realize.Under manual mode, PLC is not involved in control.The start-up and shut-down control of four groups of cooling systems is realized by hand push button in cabinet.
Under automated manner, system is controlled by PLC.In addition to automatically controlling according to operating condition, the start and stop of cooling system are also straight by backstage
Flow control protects system control.Under MANUAL CONTROL mode, each group cooler is manually controlled using the button on control cabinet panel；From
Step 4 is then carried out under dynamic model formula.
Step 4, whether entered according to converter power transformer protected mode, whether sample it is abnormal, whether period rotation, whether strong
It throw/moves back by force, whether automatically control, realize the intelligent automatic control of the converter transformer cooling system of intelligent patrol detection, and turn step
Rapid 3 repeat to judge.Specific step is as follows:
Step 4.1 judges whether cooling system enters protected mode according to the signal that direct current protecting unit issues, if
Be, stop the operation of all coolers, the slot signal then obtained according to scanning and put into operation signal the case where control cooling system
It puts into operation and goes to step 4.2, if not, turn in next step；
Step 4.1.1, on scan control cabinet involution button slot signal, if it is, manually reset, if not,
Go to step 4.1.1 multiple scanning slot signal；
Step 4.1.2, putting into operation of scanning that substation backstage provides after reset and is judged signal, if receiving the letter that puts into operation
Number, cooler put into operation, if not receiving the signal that puts into operation, going to step 4.1.2 multiple scanning and put into operation signal.
Herein, backstage signal accesses PLC system, realizes the control to cooling system, and control program is as follows: the change of current, which becomes, to be protected
PLC excision is all air-cooled after shield, and PLC enters automatic control after needing hand resetting PLC, change of current change to put into operation after protection involution again
Molding formula；Change of current change, which puts into operation, cuts stoppage in transit state, air-cooled to be stopped one by one by automatic control logic according to top oil, last group of wind
Cold operation is (configurable) after for a period of time to be stopped；It is strong to throw when the change of current becomes stoppage in transit or MANUAL CONTROL mode or change of current change guard mode
Order ceases to be in force automatically；PLC judges whether cooler has redundancy cooling capacity, and the signal is reached control protection center.
Step 4.2 judges whether sampling abnormal, if it is, then report operation irregularity to spare PLC, and start spare PLC,
And 4.3 are gone to step, if not, turn in next step.
Step 4.3, judge when transformer puts into operation whether period rotation, if it is, rotation start one group it is air-cooled and go to step
4.4, if not, turn in next step.
Step 4.4, judge whether to throw by force/move back cooler by force, if it is, open/stop corresponding cooler and go to step 4.4 weights
Multiple judgement if not, turns in next step.
Step 4.5 judges whether to enter and automatically controls, if it is, stop accordingly according to opening/stop logic and open automatically/accordingly
Cooler；
Step 4.5.1 ,/stop logic and open automatically/is opened according to top-oil temperature and circumstance temperature stops corresponding cooler；
Step 4.5.2 ,/stop logic and open automatically/is opened according to winding temperature stops corresponding cooler；
Step 4.5.3 ,/stop logic and open automatically/is opened according to transformer load stops corresponding cooler.
Herein, automatically controlling logic can configure 3 kinds of top oil, winding temperature and transformer load modes, realize
Automatic start-stop control is carried out to cooler by definite value.
Top-oil temperature and circumstance temperature open/stop logic: when top-oil temperature and circumstance temperature are lower than certain value, blower full cut-off, oil pump continues
Operation；When oil temperature and circumstance temperature are higher than certain value, fan oil pump, which continues to run, stops cooler by definite value when transformer is stopped transport, last
Group stops after operation a period of time, and oil pump or fan any starting failure when starting air-cooled, then this group of cooler startup separator is accused
It is alert；Then return system has redundancy cooling capacity to any group of cooler startup separator.Top-oil temperature and circumstance temperature open/stop the number of logic
Value range is: 45-75 DEG C.
Winding temperature opens, and/stop logic and transformer load opens/stops logic and is same as above.Winding temperature opens/stops the numerical value model of logic
Enclosing is: 55-75 DEG C；The numberical range that transformer load opened/stopped logic is specifically set, transformer according to the difference of each transformer
Its different numberical range are different.
