Embodiment 3: the emulation of micro_computer five_proof surveillance
Transformer station's micro_computer five_proof surveillance emulation is the 3rd function in the 500 kv substation analog simulation training systems of the present invention.Primary equipment simulation operations five-defence block imperfection in the domestic existing substation simulation training system product report, different with the five-defence block mode that use at the scene, can not supervise the automatic contraposition of system with the robotization backstage as five-preventing system, can not carry out the simulated operation preview, simulated operation can not be previewed step is transferred in the Electrical key, the order of operation and the mode of operation function of restriction primary equipment can not be free be thrown five anti-devices and are moved back etc.500 kv substation analog simulation training systems of the present invention for this reason carry out simulating developer to transformer station's micro_computer five_proof surveillance, the micro_computer five_proof surveillance function of using in the present electric network synthetic automating power substation is simulated, with the fidelity of enhancement training environment, the enhancement training effect.
" five anti-" computer anti-misoperation and lockout simulation system is according to actual " five is anti-" apparatus function, based on the system development of Simulation Substation human-computer interaction interface.Form by analogue simulation dish, artificial electronic lock, artificial electronic key etc.Have to throw and move back blocking device, the contraposition of mimic panel element, the simulated operation preview is write down automatically and is shown the preview content, to simulated field primary equipment transmit operation ticket, functions such as the order of operation of restriction primary equipment and mode of operation.
Each function is described in detail as follows:
(1) system of moving back is thrown in the emulation of micro_computer five_proof surveillance.
By the switching controls of man-machine interface, can realize the input of anti-error system and withdraw from.Under anti-error system input state, must carry out simulated operation in strict accordance with the anti-error rule of " five is anti-", and functions such as the order of operation of primary equipment and mode of operation. When anti-error system withdraws from, just can arbitrarily carry out the operation of simulated operation and primary equipment, this moment as generation maloperation; to produce consequence; relevant protection, switch will move, and under this state, use when desiring to know the maloperation consequence when generally being used for training and examination or during the Student Training.
(2) micro_computer five_proof surveillance analogue simulation operation.
By starting the analog functuion on the mimic panel, can realize the element on the mimic panel, automatic contraposition with on-the-spot primary equipment state, if once the physical location of equipment takes place inconsistent with the position of the analog element on the mimic panel, on the liquid crystal indication of mimic panel, point out out the title of each inconsistent equipment in position successively, revise the state of element on the mimic panel for the operator.Contraposition can be carried out the simulated operation on the mimic panel after finishing.
(3) contraposition is forced in the emulation of micro_computer five_proof surveillance.
Confirming can to use pressure to bit function under the situation of physical location with the position consistency of the analog element on the mimic panel of primary equipment, above omitting to bit function, to save time, like this, can carry out the simulated operation on the mimic panel immediately.
(4) emulation of micro_computer five_proof surveillance shows preview.
Start display simulation operation note function, can when carrying out simulated operation, see equipment and the mode of operation operated.Can close this window, cancellation shows; Also can when carrying out the primary equipment operation, provide contrast and reference.
(5) the automatic record of micro_computer five_proof surveillance emulation.
When mimic panel was operated, system got off operation process recording automatically.
(6) micro_computer five_proof surveillance emulation transmit operation ticket.
Finish at simulated operation, through confirm errorless after, by starting the transmit operation ticket function, the primary system operation order that generates is sent on the once on-the-spot five-defence block device, form a virtual artificial electronic key simultaneously, there is the identical operations ticket the inside.
(7) micro_computer five_proof surveillance emulation blocking function.
After operation order sends end, just can carry out the operation of primary equipment.Operation must be carried out release and operation in strict accordance with the order of simulated operation.If go to the wrong way at interval, perhaps draw wrong disconnecting link etc., block sytem can successfully realize anti-misoperation locking, and provides the correct prompting that should operate.
By adopting technique scheme, the on-the-spot micro_computer five_proof function of using of analog synthesis automating power substation has improved the fidelity of Training Environment, makes result of training better than in the past.
