Embodiment Construction
[0022] The core content of this patent is to carry out the line selection and cutting operation through the line selection state of the arc suppression line selection device until the bus grounding signal is reset, and cut off the grounding line with the minimum power failure cost. At the same time, part of the data in the setting sequence is also continuously passed from The power grid acquires data update iterations, and the specific implementation will be further described below in conjunction with the accompanying drawings and embodiments.
[0023] The following will describe in detail the embodiment of the method for selecting and cutting the line grounding of the 10KV arc suppressing coil grounding system provided by the present invention.
[0024] Such as figure 1 As shown, the 10KV arc suppressing coil grounding system line grounding selection method provided by the embodiment of the present invention, the method includes the steps:

The invention provides a 10 KV arc suppression coil grounding system line-to-ground selection and disconnection method. The 10 KV arc suppression coil grounding system line-to-ground selection and disconnection method comprises the steps of: receiving a grounding signal uploaded by a bus; acquiring a line selection state of an arc suppression and line selection device; and performing line selection and disconnection until a grounding signal of the bus is reset according to the line selection state of the arc suppression and line selection device. The 10 KV arc suppression coil grounding systemline-to-ground selection and disconnection method selects an optimization strategy to perform line selection and disconnection until the grounding signal of the bus is reset according to the line selection state of the arc suppression and line selection device, disconnects the line under the condition of reducing power failures of users, improves the processing efficiency of the grounding problem, and solves the problem that large-scale power outages and low efficiency are likely to be caused by performing selection and disconnection only depending on a dispatcher's experiences under the existing bus grounding condition.
Description
technical field [0001] The invention relates to the technical field of electric power engineering, in particular to a method for selecting and cutting a circuit of a 10KV arc suppressing coil grounding system. Background technique [0002] As a common 10kV grounding device, the arc suppression coil can provide inductive current to compensate the short-circuit current when a single-phase ground fault occurs in the line, which improves the reliability of power supply to a certain extent, but when the ground current is large, it will generate overvoltage, threatening personal and The grid equipment is safe, so the ground fault line should be cut off as soon as possible. The existing processing method is to directly cut off all suspicious lines, which has a great impact on large-scale power outages, and the efficiency of dealing with problems is low. Contents of the invention [0003] In order to solve the above technical problems, the present invention provides a method for ...
