Embodiment Construction

[0026] The technical solutions of the present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0027] On the A, B, and C phases at the same location of the overhead line, install the A-phase fault indicator, the B-phase fault indicator and the C-phase fault indicator respectively, and install a communication terminal on the power tower close to the fault indicator. 433MHz or 2.4GHz wireless communication modules are installed in the terminal, A-phase fault indicator, B-phase fault indicator and C-phase fault indicator, and each fault indicator communicates with the other two fault indicators and communication terminals through wireless communication. Module communication; each fault indicator has an indicator power supply voltage detection circuit to monitor the power supply voltage of the fault indicator in real time; the radio frequency transceiver chip of the wireless communication module has a rece...

Abstract

The invention discloses a fault indicator energy management method, comprising the following steps: respectively installing three fault indicators on three-phase lines; obtaining the relative time drift and initial Time offset; optimize the transmission power as the fault indicator of the wireless data sender; select the fault indicator of the cluster head, and the fault indicator of the cluster head receives the sampling information of the fault indicator of the non-cluster head, and synchronizes the time scale of the sampling point by using After synchronization, the sampling information of the non-column head fault indicator, the sampling information of the columbine fault indicator and the fault judgment algorithm are used to judge whether a fault occurs. The invention improves the accuracy rate of fault judgment of the fault indicator, greatly reduces the communication power consumption of the fault indicator, solves the problem of low false alarm and false alarm rate in the existing fault indicator, and greatly improves the automation level of the feeder.

Description

technical field [0001] The invention belongs to the technical field of fault location of electric power distribution network, and in particular relates to an energy management method of a fault indicator. Background technique [0002] In the distribution network system, there are many branches and complex operation conditions. When a short circuit or ground fault occurs, it is difficult to determine the fault section, which brings great difficulties to the maintenance work, especially in remote areas, and it takes time and effort to find it. With the advancement of distribution automation and rural power grid transformation in my country, fault indicators, as one of the technical means of distribution fault location, have been put into use in large quantities. Since the fault indicator is installed on the overhead line or in the cable trench, it is inconvenient to replace and maintain. Generally, energy harvesting CT and battery are used for power supply. The service life i...
