Embodiment Construction
[0023] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.
[0024] Such as figure 1 As shown, the present embodiment provides an identification method based on a fault indicator false alarm signal, which specifically includes the following steps:
[0025] Step S1: The distribution automation master station system establishes the memory topology of the primary equipment and the secondary equipment of the distribution network through the topology model of the distribution network; and records the topology relationship between the primary equipment and the secondary equipment before power failure;
[0026] Step S2: the master station system of distribution automation communicates interactively with the fault indicator, and obtains the data information of the operation of the distribution network terminal in real time, and the data information includes telemetry data and telesignal data;
[0027] Step S3: When the ...

The invention discloses an identification method based on a fault indicator false alarm signal, comprising steps of establishing internal memory topology of a primary / secondary device of a power distribution network through a power distribution network topology model in a power distribution automatic master station system, recording history topology relations before device power outage, obtaining an alarm signal of a fault indicator on a feeder by the power distribution master station system when power outage happens to the feeder, identifying a real effective alarm signal of the fault indicator according to a designed logic algorithm by the power distribution master station system, and recording a whole analysis process and all data related in the whole analysis process by the power distribution master station system. The identification method based on the fault indicator false alarm signal can greatly improve working efficiency of network scheduling and emergency maintenance of the power distribution network.
Description
technical field [0001] The invention relates to the field of power system distribution automation, in particular to an identification method based on false alarm signals of fault indicators. Background technique [0002] With the continuous advancement of the construction of the power system distribution network system and its practical functions, higher and higher requirements are put forward for the distribution network dispatching and emergency repair work, especially for the timeliness and accuracy of power outage fault handling. sexual indicators. [0003] It is mainly aimed at the distribution network automation terminal - the fault indicator. The working mode of the fault indicator is generally: when the fault indicator detects a sudden change in the load current of the running feeder, it will generate an alarm message and send it to the distribution automation master station. The single automation master station analyzes the alarm signal sent, and will determine the...
