Specific embodiment
With reference to embodiment and accompanying drawing, the present invention is described in further detail, but embodiments of the present invention are not limited to
This.
As shown in figure 1, being that remote automatic bus transfer equipment of the present invention differentiates that the flow process of the prepared auto restart whether successful method of action is shown
It is intended to, comprise the steps:
Distance between s11, detection and open loop point station；
S12, time delay definite value and default neighboring devices fault is waited to cut according to described distance with default judgement prepared auto restart
Except waiting time delay definite value, it is calculated the differentiation successful maximum delay of prepared auto restart；
S13, judge prepared auto restart whether action success according to described maximum delay；
The remote automatic bus transfer equipment of the present embodiment differentiates the prepared auto restart whether successful method of action, the device of different websites with
The distance of open loop website is different, by the distance between detection and open loop point station, according to this distance and default judgement prepared auto restart etc.
Treat that time delay definite value and default neighboring devices failure removal wait time delay fixed value calculation maximum delay, the device of therefore different websites
Corresponding maximum delay value can be obtained with the distance at open loop point station according to it, prepared auto restart can accurately be judged according to this maximum delay value
Whether action is successful.
For the distance between step s11, detection and open loop point station；
In power system, constitute what statements based on collusion transformer station automatic closing was powered by 110kv remote automatic bus transfer equipment
System, in system, each power station is mounted with backup auto-activating device, and the backup auto-activating device in each power station is connected using statements based on collusion mode, when going out
During existing open loop point station, each device detects the distance of its own and open loop point station first.
Wherein in an embodiment, the step of the distance between described detection and open loop point station includes:
The device of open loop website sends its positional information to two devices being adjacent；Wherein, described positional information is
Our station and the distance at open loop point station, the distance of the device of this open loop website is 0；
It is judged as that the device of non-open loop website according to the positional information of the described open loop website receiving and Jia 1 as its position
Confidence ceases, and by its positional information to receive the rightabout another neighboring devices of positional information and send, until last
Individual non-open loop point device；
