ABSTRACT:
A network emulator capable of emulating an entire restoration network improves the process of testing a centralized system for monitoring, restoration, and control of the system. The network emulator has a segmented process architecture such that emulation of the aspects of the restoration network is realized with discrete process components, including an alarm generator, an alarm feeder and a communications emulator. The alarm generator reads in a user-defined network event, analyzes network topology data to determine the impact of the event, and generates an alarms file specifying the alarms generated by the emulated network in response to the event. The alarm feeder reads additional user input specifying the nature of the event, reads the alarms file and determines the sequencing and timing of each alarm. The alarm feeder then feeds the alarms, in specific order and time intervals, to the communications emulator. The communications emulator emulates the actual communications of a network with the centralized system being tested. The communications emulator receives the sequenced alarms from the alarm feeder, formats the sequenced alarms into data messages in accordance with the specific type of devices being emulated, and transmits the messages to the centralized system being tested using an appropriate communications protocol.
