Abstract:
One embodiment of the present invention provides a system for performing a real-time, in-the-field switching-sequence simulation for a power system that includes a plurality of switching devices. During operation, the system receives, at a hand-held device, topology information associated with the power system, a set of user-definable rules, and a request to perform an operation on a switching device in the power system. In response to the request, the system identifies the switching device from the plurality of switching devices, obtains instant status information associated with the plurality of switching devices, and runs a simulation based on the topology information, the user-definable rules, the status information, and the identified switch device. The system determines whether the operation is allowed based on an outcome of the simulation.
Abstract:
A smart interlock system and a working method thereof. The smart interlock system includes a lock (1), an unlocking device (2) and a logic generator (3). The logic generator (3) comprises a logic generation module and a logic communication module. The logic generation module generates identity identification logic and state identification logic of the lock, and the two kinds of logic are sent to the unlocking device (2) through the logic communication module. The lock (1) comprises a lock tongue (102), a lock head (106) and an identity and state converting module (104). The unlocking device (2) comprises an unlocking module for starting the lock head to move, an identity identifying module (201) and a communication module. The identity identifying module (201) of the unlocking device identifies the identity of the lock, receives an identity label information which is transferred from the identity and state converting module (104) of the lock, recognizes the state of the lock tongue (102), and judges whether to unlock the lock or not according to the identity identification logic and state identification logic of the lock which are received from the logic generator (3). The smart interlock system works flexibly and enables electric anti-misoperation to be reliable and intelligent.
