Description
Technical field
The present invention relates to technical field of power systems, and in particular to a kind of realization of substation's main equipment Virtual Reality Demonstration
Method.
Background technology
With the modernization for seeing electric system, its scale is increasing, and operation operation also becomes increasingly complex.To work
The technical merit of personnel, skilful service degree etc. it is also proposed increasingly higher demands, the great deal of investment in electric system
Greatly, maintenance cost is high, it is impossible to and all using material object come to staff training, and equipment in production is for the purpose of safety,
Unlikely it is used for training.At present, electric system major part training means are all to use Training Simulation System, using more training
Instruction analogue system has Power Plant Simulation, the emulation of operation of power networks operating mode and substation simulation.Training on electric power analogue system, to train electric power
For the purpose of system operation, operating personnel, it is desirable to which emulation training environment is as true to nature as possible, it is desirable to operating mechanism, the equipment shape of emulation
State, instrument and signal etc. are identical with real system, student is had sense on the spot in person.
Realize that staff training is one trend of power industry using virtual reality technology, at present the electric power in power industry
The concept of virtual environment oneself recognized extensively.Electric system virtual environment is to generate a virtual scene, field by computer
Scape is either the reproduction or design of real electric system application scenarios and the visualization for building blueprint.Power train
If soil is made of virtual power equipment in system virtual environment, these virtual units either can by virtual operation or
It can visually reflect the result of electric analog.
Power transformer occupies extremely importantly as a kind of crucial main equipment in electric system in electric system
Position.Its influence on system operation the security of electric system, reliability and stability, it is therefore necessary to prevents and reduce transformer fault
Generation, timely State Maintenance is carried out to transformer, incident volume loss late can be reduced, improve the power supply rate of power grid, obtained
Huge economic benefit.
The operation of electric system does not allow arbitrarily to carry out, it is impossible to by the system of operation as trial target, it is impossible to is truly setting
Standby upper progress practical operation experiment, less allows artificially to set some accidents to allow student to observe and be handled.These requirements and
Limitation, makes operations staff be difficult to sufficiently be trained in the normal operating of electric system and accident treatment.
Though traditional transformer Training Methodology served it is certain, due to a lack of the sense of reality and cognition sense, result of training
It is bad.Due to the particularity of electric system so that carry out the training of transformer in the substation of actual motion, it is difficult to allowing
Time in reach satisfied effect, and lose contact with reality environment progress training, it is difficult to improve operation operating personnel in face of burst
The ability for accurately reflecting He correctly handling of accident, especially training contents depart from learning object, field conditions, caused training
Instruct ineffective.
The content of the invention
The purpose of the invention is to provide a kind of implementation method of substation's main equipment Virtual Reality Demonstration, using virtual
Reality technology builds interactive three-dimensional virtual transformer courseware and disassembles operating environment and field working conditions, emulation and multimedia technology
Integrated application can reflect assembling work visual in imagely, disassemble process and each ins and outs, solve traditional training pattern
The problem of result of training caused by middle training contents depart from learning object, field conditions is bad.
To achieve the above object, the implementation method of a kind of substation's main equipment Virtual Reality Demonstration proposed by the present invention, bag

Module, casing assembly are classified, and are resettled all kinds of individually component model storehouses, are called single component model storehouse, diminution is searched
Rope region, does not disturb the data in other component model storehouses, reduces search time.
The above-mentioned technical proposal the step of（Five）In, it must realize that part movement is advised during virtual transformer assembling
Draw, operating personnel will be captured selected part by the assembly technology path of setting, detect whether and other parts are sent out
Raw interference and collision, so as to generate the assembly sequence needed for assemble planning.
Further, in step（Five）In, the method captured to selected part is that operator is in position residing for part
Input handle corresponding information is put, judges whether equipment has with part according to the comparison of handle response position and part model position
Intersect, have intersection pickup part, do not intersect and pick up again again；If have on the sustained height of response position far and near different
Multiple parts intersect with equipment relevant position, can take the part nearest from viewpoint by software design patterns at this time, that is, take foremost
Part；If input equipment cannot reflect depth coordinate value, so the judgement of response position is the XY seats for Entry Interface
Scale value, part position is also the view field at passage XY interfaces, judges that respond coordinate has friendship in this projection domain with regard to explanation
Fork, then determines to be picked part further according to part and view distance.
Further, in step（Five）In, when having there is another part to be picked before new parts pickup, new zero
Part will realize the removing function to old pickup part while pickup, be distinguished part is picked with not being picked part, directly
The timeliness of the reaction picking action of sight, is subject to area with other parts with being picked parts profile line and be rendered to highlight color
Point, if equipment response intersects without with any part, the old pickup part of automatic rejection simultaneously removes highlight color.
Further, in step（Four）In, the planning in laggard luggage sequence ligand and path, fact is assembled parts and is being filled
Dynamic interference examination is carried out with each node in path, realizes the dynamic chek and motion simulation of the operating space of certain assembly tool,
Correct, effective assemble sequence and the description of preliminary assembly path are provided for assembling process.
The present invention carries out substation's main equipment Assembled modeling, and Assembled modeling needs clear and definite each parts of substation's main equipment
Spatial relation, specify the assembling levels of each parts.Then the planning in assemble sequence and path, fact assembling zero are carried out
Component and carry out dynamic interference examination in each node of assembly path, realize the operating space of certain assembly tool dynamic chek and
Motion simulation, correct, effective assemble sequence and the description of preliminary assembly path are provided for assembling process.
The present invention realizes substation's main equipment VR structure disassembly systems, using three-dimensional emulation technology, simulates power transformation
The dismounting cognition of inside transformer of standing structure, real internal structure is shown in virtual simulated world.Different from tradition
Picture and text explanation, mode of learning, substation's main equipment VR structures disassembly system such as on-the-spot record pass through threedimensional model true to nature, structure
Virtual environment is built, three-dimensional artificial is carried out to real equipment, scene；It is combined by Virtual Assembling Technology and VR interaction techniques
On the basis of design and Implement overall transformer Virtual assemble training system, build an assembling process definition and student learn phase
