Adopt NetMeter3.0 software to carry out the network traffics monitoring, the network traffics when continuing two minutes after the system start-up are as follows:
After bus-bar fault takes place, continue two minutes network traffics such as following table:
Can find out that from above data during long-range associative simulation training, data traffic generally can not surpass 500KB/S (scale according to transformer station changes slightly) on the network; When breaking down, the network traffics peak value is just bigger than normal a little than normal value, and the network average discharge also has certain decline than normal value; This is because just often, mainly is the variation that the electrical network electromechanical transient of transmission calculates flow state on the network, and during fault; Because in the failure process; Substation simulation only need be known the value of instant of failure, the quick change procedure of electric network swim when the student need not see fault in failure process, and the trend in the transmission fault does not change; Therefore the network average discharge reduces on the contrary, and this mode can be economized the action status information variation that more time is handled protective device.
Present technique scheme comprehensive simulation the key link of the 500kV electrical network power transmission and transformation operation of grid company under the applicant; Realized the distributed three-dimensional artificial training of 500kV transformer station; Can correctly reflect transformer station, complex automatic system and electrical network interaction, influence each other, improved the authenticity and the correctness of whole simulation training system.
This analogue system can be controlled the training that a plurality of student's platforms carry out identical or different content simultaneously through the instructor console, can satisfy the requirement that scale training and technical ability are identified.
This analogue system is the system of the be distributed in various places of a novel opening, in transformer station's man-machine interaction, adopts virtual reality technology, has realized three-dimensional substation simulation, and is easy to operate, vivid, and the student can walkaround inspection and pseudo operation in three-dimensional scenic.
The present invention can be widely used in the training field of transformation and distribution system.
