The arbitrary and all combination of the Listed Items of pass.
Substation Operating virtual scene update method of the present invention, device and the concrete application of simulation operations training system one
Scape explanation：
Primary system can refer to the high voltage electric equipment for the production process for being directly used in production, conveying and distribution electric energy.It
Generator, transformer, breaker, disconnecting switch, automatic switch, contactor, knife-like switch, bus, transmission line of electricity, electricity can be included
Power cable, reactor, motor etc..It is connected with each other by primary equipment, constitutes and generate electricity, transmission of electricity, distribution or carry out other and produced
The electric loop of journey is referred to as primary circuit or primary connection system.
The work that electrical secondary system can refer to primary equipment is monitored, controlled, adjusting, protecting and being operation, maintenance
Personnel provide the low voltage electrical equipment needed for operating condition or production command signal.Such as fuse, controlling switch, relay, control
Cable processed etc..It is connected with each other by secondary device, constitutes the electric loop for being monitored, control, adjusting and protecting to primary equipment
Referred to as secondary circuit or secondary connection system.
Operation of power networks includes transient state and stable state two states, is stable state when being usually in stable running status, during stable state
The parameters such as voltage, electric current and each equipment it is stable in order；If substation topology structure or fortune under steady state conditions, a reactor
Row state is changed, such as unexpected voltage is raised, increase, equipment catastrophic failure cause electric network state to change suddenly for load,
This moment power network changed has been put into transient process, in this process it is possible that overvoltage, excessively stream, overheat etc.
Situations such as, in the actual motion of transformer station, electrical secondary system meeting starting protection measure after these situations are monitored is cut off once
The faulty line of system and certain related section or a few sections of circuits；Transient process is temporary transient, is elapsed over time gradually
Tend to stable state, therefore reached that stable i.e. transient process terminates to enter steady-state process again through circuit after a period of time.
Specifically, the change of primary system can cause the isoparametric change of voltage on circuit, electric current, electrical secondary system collection
After to the Parameters variation of primary system if protective condition is reached starting protection, control primary system associative operation.
In actual substation operation, certain device fails causes electrical secondary system starting protection mechanism linkage cut-out once
System, field service personnel can carry out fault location, analysis reason and exclusion according to the action of electrical secondary system and the data of record
Failure etc., and traditional electric analog training system can only simulate the local scene and equipment of power system mostly, can only carry
For the outdoor scene roaming of equipment-patrolling, it is impossible to realize the linkage of primary and secondary system, therefore real power station operation can not be realized
Environment and Work condition analogue.
Substation Operating virtual scene update method embodiment 1 of the present invention：
Real power station running environment and Work condition analogue can not be realized in order to solve conventional art, causes to influence actual training
The problem of effect, the invention provides a kind of Substation Operating virtual scene update method embodiment 1；Fig. 1 is power transformation of the present invention
The schematic flow sheet of operation virtual scene update method of standing embodiment 1；As shown in figure 1, may comprise steps of：
Step S110：Confirming that transient process currently occurs in Virtual Substation system or transient process terminates to enter stable state

The operation power parameter of simulation system and secondary simulation system；
Specifically, Virtual Substation system can refer to three based on actual transformer station built using virtual reality technology
Dimension module (i.e. transformer station's three-dimensional simulation system), can realize three-dimensional artificial, roaming and the operation of substation line and equipment；It is empty
Intending transformer substation system includes a simulation system and secondary simulation system；Transient emulation, which can refer to, to be calculated transient process.
When transient process or not up to stable state occurs in Virtual Substation system, transient emulation process is triggered, current system is carried out temporary
State is emulated.
Step S120：According to emulation data, simulation system, a device model parameter for secondary simulation system are changed；
Specifically, can be according to the model object of simulation result and Virtual Substation system (i.e. during emulation
Each model data of underlying model library storage) interact, device model image parameter is changed, and read in next emulation cycle
Enter and using the first and second device model parameter changed.
Step S130：According to default secondary simulation system protective condition, after confirming to change device model parameter
When with secondary simulation system combined operation occurs for simulation system, related primary equipment mould in simulation system of control
Related secondary device model action in type, secondary simulation system；
Specifically, can be by checking that (preferably, related data can be secondary system to the related data in electrical secondary system
The data of each sensor in system) contrasted with the protective condition of electrical secondary system, determine whether there is related first and second combined operation
Situation occurs, and has, controls related first and second device action and update its state, otherwise ensures that current state is constant.
Step S140：Result based on action, updates primary equipment model, the model attributes data of secondary device model；
Specifically, model attributes data can include the product attribute data, status attribute data, connection of device model
Attribute of a relation data and fault attribute data.Because the present invention is emulated to Virtual Substation system, respective virtual is built

Operational factor, obtains Parameters variation data；
Got parms the convergence error of delta data, and Virtual Substation system current transient process is judged according to convergence error
Whether terminate and stable state can be entered.
Specifically, various embodiments of the present invention can confirm that a simulation system (priority setting confirmation primary system) and
Whether electrical secondary system (confirming simultaneously) is in steady-state operation, electrical secondary system if sensor breaks down, at this moment primary system
In stable state, but electrical secondary system is that, in transient state, this transient state will also result in the action of primary system when serious.Such as voltage sensor
It is broken suddenly, 10kV voltage measures 20kV result suddenly, at this moment electrical secondary system will enter transient state, if electrical secondary system
Protection magnitude of voltage is located between 10~20kV, then electrical secondary system will control a circuit trip protection, and this is power station operation
Real situation, and traditional training system does not account for these, it is impossible to realize the combined operation virtual field of primary and secondary system
The renewal of scape.
Fig. 2 be in Substation Operating virtual scene update method embodiment 1 of the present invention once, electrical secondary system combined operation
