Detailed description of the invention
Fig. 1 is the logic chart of relay protection apparatus control method in embodiment of the present invention method；
Fig. 2 is that the schematic diagram for enabling broadening is jumped in mutation in embodiment of the present invention method.
Specific embodiment
Technical solution of the present invention is described further With reference to embodiment.
Embodiment of the method:
The present embodiment provides a kind of relay protection device control methods, judge relay protection using multiple relay protections instruction
Whether equipment, which needs, acts, to guarantee the reliability of relay protection.
Relay protection device control method provided by the present embodiment, decision logic is as shown in Figure 1, specific steps are as follows:
(1) the corresponding relay protection instruction for same protection act is obtained from least three data sources.
Data source is the data source instructed for same protection act relay protection, i.e., can by these data sources
Obtain the relay protection instruction whether same protection act needs to be implemented.
(2) judge whether each relay protection instruction exception occurs.
Judge each relay protection instruction with the presence or absence of abnormal method are as follows: to instruct corresponding data source to set each relay protection
It is standby to be tested, if there is the corresponding data-source device of relay protection occurs overhauling inconsistent, acquisition abnormity, device power loss, number
Situations such as according to chain rupture, is then judged as the relay protection instruction exception obtained according to the data-source device.When relay protection instruction is deposited
When abnormal, relay protection instruction is marked to enable 0 for invalid jump；When relay protection instruction is not deposited when abnormal, label should be after
Electric protection instruction enables 1 for effectively jump.
(3) if each relay protection instruction is abnormal without occurring, when the relay protection instruction of more than half is effective
When instruction, control relay protection instruction outlet；
There is exception if there is relay protection instructs, then when the relay protection instruction within half is effective instruction, control
Relay protection instruction processed outlet.
As got m relay protection instruction altogether, wherein m is the positive integer not less than 3, then when in above-mentioned steps (2)
When judging each relay protection instruction without occurring abnormal, judge how many item is effectively to refer in this m relay protection instruction
It enables；
It is effective instruction that being located in this m relay protection instruction, which has n item, if n is greater than m/2, controls relay protection and refers to
Outlet is enabled, acts relay protection device, to prevent relay protection device from malfunction occur；
When judging in above-mentioned steps (2) has relay protection instruction to occur abnormal, judge in this m relay protection instruction
How many item is effective instruction；
It is effective instruction that being located in this m relay protection instruction, which has n item, if n is less than m/2, controls relay protection and refers to
Outlet is enabled, acts relay protection device, to prevent relay protection device from tripping occur.
Further, relay protection device control method provided by the present embodiment further includes that control relay protection device is hard
The step of part self-test, when relay protection device hardware check exception, control relay protection device locking is not succeeded electric protection and is referred to
It enables, does not also judge whether to need to be implemented relay protection movement.
The hardware check of relay protection device is abnormal, occurs internal processes when referring to relay protection device self-test from detection
Wrong, definite value self-test error, FLASH self-test error, outputs circuit breaking, outputs the failures such as loop breakdown RAM self-test error.
In order to guarantee the reliability of relay protection device movement, it is provided with to be mutated in relay protection device and jumps order broadening,
Mutation, which jumps to enable broadening, refers to there is the effective trip signal of of short duration mutation in data source signal, carries out reliability and acts at least 40ms, mistake
Journey signal as shown in Fig. 2, specifically: the mutation that end 1 receives 1ms, which is jumped, to be enabled, that is, is inputted a value and be 1, continue the mutation of 1ms
Jump and enable, then 50ms is broadened by the broadening element of front, hold 2 be value be 1 and holding when a length of 51ms instruction, i.e., simultaneously
The instruction of a length of 51ms when holding 4 value to be 1 and keep, is arranged a delay cell between end 2 and end 3, and the value at end 2 is
When 1, value is just 1 after 3 delay 40ms of end, i.e., preceding 40ms value is 0, i.e., through negating logic at end 3,40ms value is 1 before becoming, together
When and end 4 carry out logical ANDs, obtain end 1 at broadening jump enable 40ms.
When the prolonged mutation jump of 1 reception of end one enables, end 5 is directly walked, long-term jump is obtained at end 6 and is enabled.
Installation practice:
The present embodiment provides a kind of relay protection device control device, including memory and processor, stored on memory
There is the computer program for executing on a processor；Processor is realized as above when executing the computer program stored on memory
State relay protection device control method provided in embodiment of the method.
Specific embodiment of the present invention is presented above, but the present invention is not limited to described embodiment.
Under the thinking that the present invention provides, to the skill in above-described embodiment by the way of being readily apparent that those skilled in the art
Art means are converted, are replaced, are modified, and play the role of with the present invention in relevant art means it is essentially identical, realize
