Background
At present, the national power grid field actively promotes the construction of the smart power grid, and the intelligent feeder automation terminal based on the three-remote foundation is the important equipment for implementing the smart power grid. Wherein remote signaling is an important component of three remote.
Feeder automation terminal equipment is usually used in cooperation with a switch, the feeder automation equipment mainly collects the remote signaling state of the switch, and remote signaling signals are important components of power grid dispatching and reflect the actual operation conditions of the field terminal equipment and the switch. In combination with the actual use condition on site, the quick-break protection is usually used more, the switch acts quickly, the time is often quick, the time is usually second-level or even millisecond-level, and under the condition, the accurate acquisition of the remote signaling signal is an important task of the feeder terminal. Because the jitter condition often exists during the switching action, if the feeder line terminal can not accurately identify the signals with jitter, the scheduling personnel can not make corresponding countermeasures in time, and wrong basis is brought for the analysis afterwards. Since these jitters are a defect existing in the electrical device itself, it is necessary to eliminate this defect by software.
The anti-shake function is a necessary function for each manufacturer, and the anti-shake function means that the remote signaling is kept for a certain time and then is regarded as an effective remote signaling signal. But the practice of each family is somewhat different.
