Abnormal, troubleshooting training, by the emulation of accident in two kinds of situation, a kind of is the accident set, and another is maloperation Accident, this failure triggers naturally in a model；System can analog line, bus, transformer, capacitive reactance device failure, and can be set CT dead-zone faults, overlay region failure, breaker both sides node failure；Switch failure, relay fail, malfunction also can be set to expand Accident scope；System can temper monitoring personnel analysis judgement accident ability；

Defect processing training, safety but not yet constitution equipment exception and accident treatment are jeopardized for training；Realize at equipment deficiency Training is put, the susceptibility of monitoring personnel is tempered, monitoring personnel is strengthened the judgement of power system abnormal signal, root According to various device models, different defect situations can be set in teacher, temper student and reject interference signal in prison disk work, in time Accurately find various defects and carry out respective handling.

9. intelligent grid Dispatching Control System according to claim 1 regulates and controls Integrated simulation experience system, it is special Levy and be：Dispatcher training analog subsystem, monitor's training analog subsystem also include Combined anti-accident maneuver module, are used for The person of being scheduled, the Combined anti-accident maneuver of monitor, improve various accident counte-rplan, to improve by instruction personnel's accident conditions Under quick correct decisions ability and collaboration adaptibility to response, overcome conventional Combined anti-accident maneuver to talk about stratagems on paper, concertedness difference Limitation.

10. intelligent grid Dispatching Control System according to claim 1 regulates and controls Integrated simulation experience system, it is special Levy and be：Regulation and control center emulation module is provided with the integral supporting assembly of regulation and control, Centralized Monitoring component, comprehensive warning component；

First, regulating and controlling integral supporting assembly includes：

1) integral rights management unit is regulated and controled

By all system resources, including executable operation, picture, interface, polymorphic include regulation and control one rights management；Control of authority Two levels of subangle color and user；Business responsibility identical user's group is defined as role, including dispatcher, monitor；The use The user that the public authority of family group is directly authorized under role, role inherits the mandate of affiliated role automatically, simplifies management and safeguards Workload；Personalized customization can be carried out to particular user；

2) information layered differentiated control unit

All items and warning information, including alarm bar, alarm list etc. support authority and zone of responsibility filtering；Only show user Various items and warning information in compass of competency；

3) the man-machine display unit of one is regulated and controled

Regulate and control the function interface of integrated system, tissue is carried out according to user role；After each Role Users login system, opening The function interface centralized displaying role, such as dispatcher, required function；The function that each role can use is configurable 's；Dominant role type includes：Dispatcher, monitor, keeper；

The listed function of role is supported, the board that dispatcher hangs is only displayed in scheduling operator interfaces, and the board that monitor hangs is only displayed in monitoring Operator interfaces, the board that automation personnel is hung is only displayed in the interface of automation personnel；Every kind of board can be operated by which role, at which A little Role Users can be shown after logging in, and which Role Users shielded signal can be customized, by man-machine carry out control of authority；

Support defines the role associated by it for a certain kind equipment on line chart, and then realizes that line chart content role customizes；

2nd, Centralized Monitoring component includes

1) monitoring data processing unit

For the integral operation characteristic of regulation and control, on the basis of original scheduling EMS system analog quantity, quantity of state processing, increase is supported：It is disconnected Road device coherent signal, route protection and control loop coherent signal, main transformer body coherent signal, main transformer protection and control loop phase OFF signal, bus protection and control loop coherent signal, capacitor protection and control loop coherent signal, the collection of common signal Function；

2) zone of responsibility and shunting information unit

The function of system is realized for the definition according to zone of responsibility and carries out refinement segmentation, can be real to specific zone of responsibility object Existing corresponding function privilege, including each functional steps are clearly divided；Can be according to specific zone of responsibility dividing system Distant control function；The shunting information technology according to zone of responsibility is realized, with reference to the transmission information of system, each center monitoring work is realized Stand and only handle the area of responsibility domestic demand information to be processed；Warning information window also only shows the alarm related to the area of responsibility Information, dispatcher, monitor's operation are also only effective to the equipment in area of responsibility, serve information between each workstation nodes Layering and the effect safely and effectively isolated；

3) alarm window unit

Alarm window shows that it is made up of whole station light word figure, interval light word figure and interval detail view for man-machine interface；Three kinds of light words Figure is linked by the three-level completion of falling tree each other, constitutes light word subsystem；Light word figure is according to the secondary model data of system one The signal structure in storehouse is automatically generated, and light word operating state color point is corresponding with the alarm level of signal, can flexibly be set per grade Put；Involution state is set for uniform color；

4) operation and control unit
