The test system disclosed by the invention can be used for carrying out simulation test on the protection system in advance and has the capability of finishing upgrading of the protection system under the condition of not powering off.
Description
Technical field
The present invention relates to the substation protection system, relate in particular to the test macro of substation facilities protection system.
Background technology
The large-scale transformer and distribution station of China is built in the eighties in last century more, can not satisfy the needs of modern power systems management mode far away to its means of relay protection now, therefore must upgrade to original protective device.Be because the power supply object of large-scale electric substation all is some important production unit and places; For the economic loss that house of correction is produced minimizes; Just must in that do not have a power failure or short as far as possible power-off time, upgrade to protective relay; Otherwise just necessary power down process will cause very big influence to worker, civilian electricity.
Summary of the invention
The present invention is intended to address the aforementioned drawbacks, and a kind of substation facilities relay protection system simulated testing system is provided.The present invention can carry out simulation test to protection system in advance, can not accomplish the upgrading of protection system with cutting off the power supply.
A kind of substation facilities relay protection system simulated testing system; It comprises protective device to be tested, relay-protection tester and one couple together protective device to be tested and relay-protection tester through the wire harness cable junction box, and said test macro also comprises:
A prepackage has the terminal of dependence test software, and this terminal connects said relay-protection tester through CAT5E UTP cable;
A Programmable Logic Controller, it is connected with described terminal through fieldbus, is connected with the wire harness cable with the junction box, is connected with the wire harness cable through fieldbus with protective device to be tested.
The present invention can simulate the practical operation situation behind the protective device upgrading truly, be convenient to find in advance to design and equipment in the problem that exists, and solve.
Description of drawings
Below, in conjunction with accompanying drawing, the present invention is further described
Fig. 1 is a synoptic diagram of the present invention.
Embodiment
As shown in Figure 1; A kind of substation facilities relay protection system of the present invention simulated testing system; It comprises protective device to be tested 1, relay-protection tester 2 and one couple together protective device 1 to be tested and relay-protection tester 2 through wire harness cable 10 junction box 3, and said test macro also comprises:
A prepackage has the terminal 4 of dependence test software, and this terminal connects said relay-protection tester 2 through CAT5E UTP cable 11; A Programmable Logic Controller 5, it is connected with described terminal 4 through fieldbus 12, is connected with wire harness cable 10 with junction box 3, is connected with wire harness cable 10 through fieldbus 12 with protective device 1 to be tested.Described test macro also comprises a power supply of supplying power to test macro incessantly.
Embodiment
Simulator program is write
Combined floodgate logic and the separating brake logic of using Programmable Logic Controller (S7-300) to come analog switch; According to actual switch once with secondary hardware device, and its branch, closing locking condition; Establishment one cover soft logic program, thus reach purpose to the emulation of relay protection logic testing signal system.Below provided " branch, the combined floodgate logical design thinking of isolating switch commonly used ".
The establishment of MI picture
Through Siemens SIMATIC WINCC human interface software; Write the pictures such as status surveillance, fault alarm, Data Detection of cover electric substation each equipment in conjunction with electric substation's actual motion state, simulation realizes internal data communication tests such as the remote control, remote measurement, remote signalling of electric substation.
Analogue means inserts
After having accomplished work such as programming in logic and the establishment of HMI picture, just can carry out the access test of analogue means, whether the test simulation loop can true(-)running, and detects the degree of compatibility of tested device for original system.Fig. 4 is the line chart of analogue means.
Realistic simulation signal for high-voltage switch gear one action condition, secondary singal and operating power etc. passes through the simulation test junction box, realizes the switching value simulation.Each section busbar voltage, line voltage distribution, electric current and signals such as meritorious and reactive power are realized the analog quantity simulation through the relay protection tester.
The network signal test
Through the S7-300 programming software, detect the correctness of protective relay to HMI picture signal, and the consistance of each protective relay terminal address and the corresponding station of picture.
The present invention improves substation protection system update upgrading safety of construction; Substation protection system upgrade in the past; Only do the monomer test of protection equipment early stage; Chain and internal data communication all must be tested after equipment replacement to the logic between the protection system, if run into design mistake or with the unmatched situation of legacy system interface signal, very easily cause electric substation's tripping operation accident.Our this cover simulation device; Can under off-line case, accomplish complete analog simulation test to protection equipment; And all signal transfer of the device that can be replaced needs through the bypass switching way can improve online construction to greatest extent and transform accuracy and safety coefficient to the model test device.
The present invention shortens the power off time that substation protection system update upgrading construction is transformed; Because signal testing must carry out at the construction field (site) in the past; The transformation time of such covering device need be used 3～5 days; Use the analogue means test signal, the renewal update time of single cover facility only just can be accomplished with 2～3 days at present.
