Description
Technical field
The utility model relates to the logic testing device of microcomputer type protection control module in a kind of power supply-distribution system.
Background technology
In power supply-distribution system, traditional relaying protection secondary control loop all adopts pure hardware such as auxiliary relay, the time relay to build, and realizes the logic control and the condition locking of various defencive functions.In system debug or maintenance process; the reaying protection test personnel must be at the scene; the various failure conditions and the abnormal running state of simulation power supply-distribution system; the operating characteristics of all kinds of protection relays in the test macro; and carry out the operation of high-voltage switch gear on the spot; operate the test position as high-voltage switch gear; working position; ground connection cutter and higher level's mains switch close; the separating brake position; and to relevant secondary singal; operating powers etc. are operated on the spot; just can carry out the linkage test of relaying protection, thereby judge the correctness and the integrality of relaying protection secondary control loop in the power supply-distribution system.
In recent years, along with development of computer, the relaying protection secondary control loop has been widely applied microcomputer type protection control module (also claiming complex protection device) in the power supply-distribution system, the secondary control loop of power supply-distribution system relaying protection is progressively changed into by programmable protection logical program in the microcomputer type protection control module by the mode of building of pure hardware in the past realizes that building of relaying protection secondary control loop realized software implementation; And, can protect also that control simulation able to programme realizes in the control module by microcomputer type to the judgement that high-voltage switch gear closes, whether the operation of separating brake and operating condition satisfy.
Logic testing to microcomputer type protection control module in the power supply-distribution system at present mainly contains following several scheme:
Scheme one:
Use special-purpose relay-protection tester device; the various faults and the abnormal running current/voltage value of simulation power supply-distribution system; current/voltage is imported microcomputer type protection control module, by the defencive function and the operating characteristics of special-purpose relay-protection tester device test microcomputer type protection control module self.
The method of microcomputer type protection control module can only be carried out the test of microcomputer type protection control module autoprotection function and operating characteristics value in the special-purpose relay-protection tester device test of the above-mentioned utilization power supply-distribution system; as test the operating value of overcurrent protection; return value, operate time etc.If microcomputer type protection control module inside also has programmable protection logic OR control logic, then use special-purpose relay-protection tester device to test.
Scheme two:
At on-the-spot relay-set place of power supply-distribution system or high-voltage switch gear place, use special-purpose relay-protection tester device, give and be installed in the on-the-spot microcomputer type protection control module input simulation various faults of power supply-distribution system or the current/voltage of abnormal running, in order to the protection operating characteristics of test microcomputer type protection control module and the correctness of high-voltage switch gear trip(ping) circuit; Also the simulation of various signals be can carry out at the scene, the closing of high-voltage switch gear, separating brake control test carried out.

Cause the high-voltage switch gear deciliter harmful effect that brings repeatedly for fear of repeatedly relaying protection linkage test; before high-voltage switch gear is not finished debugging or under the control DC power supply of high-voltage switch gear and protection, the signal power source situation about not dropping into; adopt special-purpose " circuit breaker analogue means ", be used for whole group of intertrip test of relaying protection function.This scheme needs special-purpose relay-protection tester device equally, moves needed current/voltage signal to produce defencive function.
This scheme can be finished the defencive function and the operating characteristics test of microcomputer type protection control module; Can finish the linked switch test of relaying protection function; But can not protect the FPGA (Field Programmable Gate Array) of control module to carry out system testing to microcomputer type.Auxiliary equipment signal and extraneous signal were simulated inside the Pass special-purpose " circuit breaker analogue means " can not be split, and its main purpose is branch, the combined floodgate of simulated high-pressure switch, avoided the protection linkage test of repetition to cause the harmful effect that switch divides repeatedly, crossed belt comes.
In the power supply-distribution system, can whether the interior logical program establishment of microcomputer type protection control module be correctly extremely important, determined the relaying protection function realize, determined that also high-voltage switch gear closes, the fail safe of sub-switching operation.Therefore extremely important to the logic testing of microcomputer type protection control module, and above-mentioned each testing scheme is had relatively high expectations to the technical ability of testing crew, the ordinary test personnel are difficult at the scene fast, expertly finish test, and need long interruption duration; The risk of on-the-spot actual test is higher simultaneously, is unfavorable for the safe operation of power supply-distribution system; Owing to be subjected to the influence of actual production, some specific functions or the outer signals condition of power supply-distribution system can't satisfy in addition, and therefore the effective sex ratio of test is relatively poor at the scene.
