Abstract

The invention discloses a failure processing method and device of a voltage and current hybrid line. The failure processing method of the voltage and current hybrid line comprises the steps that whether the power grid hybrid line has a failure or not is judged; if it is judged that the power grid hybrid line has the failure, a failure section of the power grid hybrid line is detected; whether a load transfer section exists or not is judged; whether a load transfer path exists or not is retrieved; if it is judged that the load transfer section exists, and the load transfer path is retrieved, transfer processing is carried out on the load of the failure section. Through the failure processing method and device of the voltage and current hybrid line, the problem that the failure of the voltage and current hybrid line is hard to effectively process is solved.

Description

Technical field [0001] The invention relates to the field of power grids, and in particular to a method and device for processing voltage and current hybrid line faults. Background technique [0002] Traditional distribution lines can be divided into voltage-type lines and current-type lines according to accident handling methods. [0003] When an accident occurs on a voltage-type line, it relies on the function of the terminal itself to realize the isolation of the accident section and the transfer of the load in the non-accident section; when an accident occurs on a current-type line, DAS relies on the collected fault signal on the current-type terminal, and the DAS system makes the accident section judgment. It also provides solutions for isolation of accident areas and load transfer in non-accident areas. [0004] Because voltage-type and current-type line accident handling mechanisms are fundamentally different, when voltage-type switches and current-type switches are mixed on ...
