For example: Nan Ruiji protects PCS-931, and the optical fiber phase-splitting is differential:
The pretest inspection channel status: no error code, error code, channel delay confirm that less than 16ms passage is normal, do not send out channel alarm information.
Offside is sent out and is allowed the condition of signal to have:
1, protection of this side and difference element start;
2, this side is jumped the position and is not had stream;
3, weak feedback logic;
Pilot project:
1, this side switch closes the position, and the offside switch is closing the position, and the both sides relay-protection tester inserts gps clock, IRIG-B sign indicating number clock respectively; Add fault current; When fault current during greater than the differential protection definite value, the tripping operation of this side protection step switch, the tripping operation of offside protection step switch.
2, the weak feedback of simulation function: the both sides relay-protection tester inserts gps clock, IRIG-B sign indicating number clock respectively, and the offside switch is closing the position, and the main protection pressing plate drops into; Add normal this phase voltage 34V, less than 65%Un but greater than TV broken string alarm voltage 33V, device nothing " TV broken string " signal; This side switch is closing the position; Intend various faults at this side form, when fault current during greater than the differential protection definite value, equal would trip is protected in both sides.
3, the far away jumping tested, and makes this side switch close the position, and when this side " was far jumped and received this side control=0 ", offside made protective device have tripping far away to go into, this side protection transfer trip.When this side " was far jumped and received this side control=1 ", when offside made protective device have tripping far away to go into, this side protective device started, the transfer trip of this side defencive function.
Advantage of the present invention:
Intellectuality of the present invention and conventional substation optical-fiber longitudinal difference protection passage united test method, intelligent transforming plant protecting adopt light IRIG-B sign indicating number synchronously to the time mode, conventional substation adopt GPS to the time mode; Utilize above-mentioned two kinds of clocks to accomplish and the synchronized sampling of protecting synchronized sampling and triggering both sides tester; Accomplish the multiple spot synchronous acquisition, trigger test, assurance both-end digital protecting tester is exported the fault sampled value simultaneously and is given tested protective device, realizes the test to both-end fibre-optic current longitudinal difference protection; The action definite value and the action logic of protective device have promptly been verified; Also verified the correctness of the optical fiber link of two ends protections, test method is easy, and data are accurate.
