Description of the drawings
Fig. 1 is the method for the present invention flow chart.
Specific embodiment
The present invention is described in detail with specific embodiment below in conjunction with the accompanying drawings.The present embodiment is with technical solution of the present invention
Premised on implemented, give detailed embodiment and specific operating process, but protection scope of the present invention is not limited to
Following embodiments.
As shown in Figure 1, a kind of grid equipment electriferous state method for verifying correctness based on multi-data source includes：
Step S1：Power supply point, earth point, the state of switchgear and ground connection board are set as grid equipment electriferous state
Boundary condition factor, grid equipment include cut-off kind equipment and bus equipment.
Power supply point is configured respectively according to power plant and interregional grid；
In power plant, in the case of power plant is covered in administration of power networks in PMS systems, according to power plant's primary connection figure and fortune
Line mode safeguards the degree that becomes more meticulous, and becomes by generator, boosting, priority carries out power supply point setting to power plant's outlet successively；
In interregional grid, power supply point is arranged on the transregional circuit in interregional grid.
Setting holding of the setting of ground wire with being grounded board is synchronous.There is " ground wire " model, according to implementation in PMS systems
Specification, ground wire needs to safeguard in power station, and ground wire has ground connection attribute and behavior.Meanwhile there is " ground connection " mark in PMS systems
Know board, after work on the spot mounting is grounded, dispatcher synchronously carries out the board operation of mounting ground in systems, and being grounded board has ground connection
Property and behavior.
Step S2：Electriferous state and ground state are obtained according to grid equipment topological structure.
21) obtaining step of electriferous state is：According to grid equipment topological structure, since power supply point, traverse and cut-off
The equipment that the state of kind equipment cut-offs board to disconnect or hanging, then stop traveling through, and the part traveled through is electriferous state, is not traveled through
Part is non-charged state.
In ergodic process, " powering " situation is run into, and processing rule is as follows：
When transformer identity becomes for boosting, then it is normal to sentence knowledge, continues to travel through；
When transformer identity becomes for non-boosting, then it is abnormal to sentence knowledge, stops traversal；
When transformer does not identify, then continue to travel through, and form warning matters, prompt staff do further sentence knowledge,
Confirm.
When charged calculating runs into " looped network " situation, record ring dot location (can check looped network by client utility
Information).
22) calculating of grid equipment ground state is similar with charged calculating.Therefore, the obtaining step of ground state is：Root
According to grid equipment topological structure, since earth point, traverse and cut-off the state of kind equipment to disconnect or hanging the equipment for cut-offfing board,
Then stop traveling through, the part traveled through is non-charged state, and the part not traveled through is electriferous state.
Step S3：The electriferous state of acquisition with telemetry intelligence (TELINT) is mutually verified, while by the electriferous state of acquisition and is connect
Ground state is mutually verified, and obtains the electriferous state check results of correctness.It is specifically described below：
31) the step of electriferous state of acquisition and telemetry intelligence (TELINT) being carried out and mutually verified be：
For cut-offfing kind equipment, the telemetered signal for cut-offfing kind equipment is obtained, telemetered signal includes power or electric current, when cut-offfing
The state of kind equipment is disconnects, and when the amplitude of power or electric current is more than drift limit value, sentences knowledge to be abnormal, forms thing to be confirmed
, it accordingly cut-offs kind equipment and is labeled as abnormal main body；
For bus equipment, when the state of bus equipment is not charged, and bus equipment voltage magnitude is limited more than drift
During value, knowledge is sentenced for exception, forms item to be confirmed, and respective bus bars device flag is abnormal main body.
32) the step of electriferous state of acquisition and ground state being carried out and mutually verified be：Same grid equipment occurs charged
When state and ground state conflict, sentence knowledge to be abnormal, form item to be confirmed, closest to earth point grid equipment labeled as different
Normal main body.
What is primarily solved using virtual reality technology is to inform that each level personnel equipment has electricity condition, by one point data
Differentiate that instruction is often influenced be subject to other equipment operation characteristic in power grid, such as ground wire, ground connection board, earthing switch blade are set
It is standby.Therefore the mode that joint judges must be taken to be corrected the final data loaded to device model.The main face of the present invention
Correctness verifying function is shown for virtual reality power grid platform device electriferous state, goal in research is by company to object
The various information systems such as SCADA, DSCADA, PMS, load control system, marketing management system are come the fortune that obtains and summarize power grid
Row data, these data include the remote signalling data of power system operating mode, the telemetry of operation of power networks state and operation of power networks and
The electric degree data of operation of power networks benefit.It fully understands the operation logic of all kinds of grid equipments, data is combined with operation logic,
So as to improve the accuracy of equipment live state.
In application, to telemetering, remote signalling (off-state and closure state) in each electric loop etc. in power network GIS platform
Real time information establishes the software of a set of method of calibration of the present invention, by multiple system real-time verification, carrys out proving correctness and can
By property.Finally, the result loading of method of calibration is being needed to indicate each position of charged equipment, so that it may equipment belt be explicitly indicated
The situation of electricity strong has electric prompting to staff is a kind of.
