The fault simulation is a separately available module, which trains operators in locating and resolving faults. This involves 'unknown' faults in the network. The operator commnunicates with the network by receiving automatic and telephone notifications, remote control and station actions. At a station, the operator can view the protection relays photographically. Time records are kept of the actions performed. Fault consumption minutes are also recorded. This quantitative appreciation of the resolution process gives fault simulation a competitive element.
Fault simulation uses the following inputs:
•a Vision network
•images of protection relays'
•an image information file.
Network file
The network file contains the utilities required for displaying the images:
•The short name of a protection relay must match a name in the image information file
•In a differential protection and short-circuit relay, this name must be added as a value to the 'type' attribute.
In the network file, voltage transformers can be specified in the details of a node: 'voltage transformer=TRUE' or 'voltage measurement transformer=50', where the number defines the sign location at the node.
