Some embodiments of the present application, instead of all the embodiments.Based on the embodiment in the application, those of ordinary skill in the art
Every other embodiment obtained without making creative work, shall fall in the protection scope of this application.
Referring to FIG. 1, Fig. 1 is a kind of process signal of the excitation method of excitation system provided by the embodiment of the present application
Figure；With reference to Fig. 1, which includes:
S101: monitoring the set end voltage of generator and judges whether set end voltage is less than the specified generator terminal electricity of preset ratio
Pressure；
Specifically, will lead to excitation system misidentification since voltage disturbance occurs for measurement circuit during excitation system excitation
For excitation success, and enter the logical program of normal soft excitation, and the collection value of the set end voltage of generator is always during this period
It is zero.As a result, in the application excitation system can real-time monitoring generator set end voltage, to be sentenced according to the set end voltage of generator
Whether the excitation for the first time of disconnected excitation system fails, and is less than the voltage rating of preset ratio as excitation using the set end voltage of generator
System carries out the Rule of judgment of second of excitation.It should be noted that above-mentioned excitation system excitation is unsuccessfully by measurement circuit hair
Caused by raw voltage disturbance, it is different from and is failed by excitation system excitation caused by relevant electrical component failure.
Wherein, unique restriction is not done for specific value the application of above-mentioned preset ratio, can according to actual needs into
The setting of row otherness.Since the set end voltage of generator after the failure of excitation for the first time is zero always, therefore above-mentioned preset ratio can be set
It is set to a lesser numerical value, for example, can be set to 10%, it is corresponding, that is, judge whether the set end voltage of generator is less than
10% specified set end voltage.
S102: if set end voltage is less than the specified set end voltage of preset ratio, judge that monitoring system issues excitation system
Whether excitation system, which meets, after the first preset duration after investment instruction is moved back excitation system condition；
S103: if excitation system satisfaction moves back excitation system condition, excitation system excision instruction is sent so that excitation system
It exits；
Specifically, monitoring system issues after excitation system investment instructs, (excitation system investment instruction can keep a timing
It is long) the i.e. transmittable excitation system investment instruction in excitation system inside, thus excitation system investment.In the generator terminal electricity for judging generator
Pressure is less than on the basis of the specified set end voltage of preset ratio, this step further judges that issuing excitation system in monitoring system throws
Whether excitation system, which meets, after the first preset duration after entering is moved back excitation system condition.
Wherein, for the specific value of above-mentioned first preset duration, the application equally without limitation, in conjunction be actually needed into
The adaptable setting of row.Enter soft excitation operation after a certain period of time due to being mistakenly considered excitation success in excitation system
(usually 12 seconds), soft excitation terminates, and excitation system, which can be reported by mistake, encourages limitation and rotor inverse-time overcurrent limitation movement, because
This, the first preset duration can be set in conjunction with time of above-mentioned soft excitation, the case where being such as 12 seconds for the soft excitation time,
First preset duration can be set to 15 seconds etc. greater than 12 seconds, certainly, it is contemplated that the factor of available machine time, the first preset duration
It should not be too large, to ensure the efficiency that is switched on.
Since interference voltage is accidental instantaneity interference, excitation system excitation is caused to fail when interference voltage occurs
Afterwards, if putting into again after excitation system is exited, excitation system can normal excitation again again.Based on this, when judging excitation
System satisfaction is when moving back the basis of excitation system condition, i.e., the operation that implementable excitation system exits.Specifically, in excitation system
Portion sends excitation system excision instruction, exits excitation system.
Wherein, in a kind of specific embodiment, above-mentioned excitation system condition of moving back may include receiving excitation system
The control mode of investment instruction and excitation system be automatic running mode and without excitation failure signal and set end voltage be less than it is default
The specified set end voltage of ratio.I.e. when above-mentioned each condition is all satisfied, excitation system excision instruction is issued inside excitation system, with
Exit excitation system.It should be noted that above-mentioned excitation failure signal leads to excitation system excitation for electrical component failure
Generated excitation failure signal when failure.If showing that there are electrical component failure, excitation systems with the presence of excitation failure signal
System still can not normal excitation, therefore, excitation failure signal can be used as the barring condition of secondary excitation, i.e., once there are excitation mistakes
Signal is lost, just will not implement secondary excitation again.
S104: whether excitation system is full after judging the second preset duration after monitoring system issues excitation system investment instruction
Put into excitation system condition enough；Wherein, the second preset duration is greater than the first preset duration；
S105: the system condition if excitation system satisfaction puts into excitation, the system that puts into excitation carry out excitation system excitation.
Specifically, judge monitoring system issue excitation system investment instruction after the second preset duration after excitation system whether
Meet the system condition that puts into excitation, that is, after judging that excitation system exits, whether excitation system meets the system condition that puts into excitation,
With when excitation system satisfaction puts into excitation system condition, excitation system is put into again again.Specific excitation system is meeting investment
When excitation system condition, inside can send excitation system investment instruction so that excitation system put into.
Wherein, it is betided after excitation system exits since excitation system is put into again, the second preset duration is greater than the
One preset duration.And for the specific value of the second preset duration, the application is without limitation.For example, being set in the first preset duration
In the case where being set to 15 seconds, the second preset duration be can be set to 23 seconds.
In addition, the above-mentioned system condition that puts into excitation may include: to receive monitoring system in a kind of specific embodiment
Unite the instruction of excitation system investment and excitation system that issue control mode be automatic running mode and without excitation failure signal and
Set end voltage is less than the specified set end voltage of preset ratio.
Further, in a kind of specific embodiment, which can also include: to judge that monitoring system issues to encourage
Whether excitation system meets excitation failure alert if after third preset duration after magnetic system investment instruction；Wherein, third is pre-
If duration is greater than the second preset duration；If excitation system meets excitation failure alert if, excitation system excitation failure is carried out
Alarm.
Specifically, in the present embodiment, still if being disturbed voltage influence when excitation system progress second of excitation operation
Excitation failure, then carry out excitation and unsuccessfully alarm, unsuccessfully remind to carry out excitation in time.Specific is to judge that monitoring system issues to encourage
Whether excitation system meets excitation failure alert if after third preset duration after magnetic system investment instruction；If excitation system is full
Sufficient excitation failure alert if, then carry out excitation system excitation and unsuccessfully alarm.Wherein, above-mentioned third preset duration can refer to second
Preset duration carries out adaptable setting, and such as the second preset duration is set as 23 seconds, third preset duration is set as 32 seconds.This
Outside, above-mentioned excitation failure alert if may include: that set end voltage is less than the specified set end voltage of preset ratio and loses without excitation
Lose signal.
Further, in a kind of specific embodiment, if the excitation method can also include: to receive under monitoring system
Hair moves back excitation system instruction, then excitation system exits；Excitation failure signal if it exists then carries out excitation system excitation and unsuccessfully reports
It is alert.The excitation system of moving back that i.e. excitation system once receives that monitoring system issues instructs, and excitation system will exit.Once excitation
System receives excitation failure signal, and excitation system just will do it excitation and unsuccessfully alarm.In addition, excitation system carries out excitation failure
It can also be sent after alarm and cut off excitation order existingly, unsuccessfully alarmed with resetting excitation, and the excitation that monitoring system issues at this time
The holding duration of system investment instruction terminates, i.e., there is no the excitation system investment instructions that monitoring system issues at this time.
In conclusion the excitation method of excitation system provided herein, introduces the operation of secondary excitation, and with hair
Condition of the set end voltage of motor as secondary excitation, by monitoring the set end voltage of generator, when judging that set end voltage is less than
When the load voltage value of preset ratio, i.e., when voltage disturbance occurring and excitation for the first time is caused to fail, provided herein is risen
The method of encouraging exits excitation system after moving back excitation system condition judging excitation system satisfaction, and is judging excitation system satisfaction
