Embodiment 1
[0041] Embodiment 1. A method for locating faults in a station area based on the integration of operation and distribution includes the following steps:
[0042] Inject the pulse signal from the end of the line branch, and receive the perception confirmation message and its identity sent by each fault indicator on the line in response to the pulse signal; according to the message and identity sent by each fault indicator on the line and the branch line The position of the exit circuit breaker determines the hierarchical relationship of the network topology; the network node relationship of each fault indicator and circuit breaker on the line is determined according to the network topology;
[0043] Based on the determined network node relationship, the fault is located according to the fault data sent by each fault indicator and circuit breaker when the fault occurs, and the fault location result of the station area is obtained.
[0044] The fault indicator described in this e...
Embodiment 2
[0046] Embodiment 2. On the basis of the embodiment, this embodiment optionally further includes the following step after identifying the network topology level: generating event alarms such as device change and topology update according to the identification result.
Embodiment 3
[0047] Embodiment 3. This embodiment provides a station area fault location method based on the integration of operation and distribution, including:
[0048] The pulse signal is injected from the end of the line branch, and the intelligent distribution transformer terminal receives the perception confirmation message and its identity sent by each fault indicator on the line in response to the pulse signal;
[0049] Determine the network topology hierarchy according to the message and identity sent by each fault indicator on the line and the position of the outlet circuit breaker on the branch line;
[0050] Determine the network node relationship of each fault indicator and circuit breaker on the line according to the network topology;
[0051] Based on the determined network node relationship, the fault is located according to the fault data sent by each fault indicator and circuit breaker when the fault occurs, and the fault location result of the station area is obtained. ...
