Embodiment Construction

[0032] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0033] like figure 1 As shown, in the embodiment of the present invention, a method for rapidly processing secondary circuit parasitic defects is provided, and the method includes:

[0034] Step S1, when the secondary circuit wiring has a parasitic circuit defect, determine the parasitic phenomenon of the current secondary circuit; wherein, the parasitic phenomenon includes homologous parasitic phenomenon and heterologous parasitic phenomenon;

[0035] It should be noted that the parasitic phenomenon of the current secondary circuit can be determined by looking for the source of the parasitic phenomenon. Due to the heterogeneous parasitic phenomenon, it can be determined by disconnecting the secondary circuit power supply circuit breaker with simple wiring or clos...

Abstract

The invention provides a method for rapid processing of a parasitic defect between secondary circuits. The method comprises the following steps of determining a parasitic phenomenon of the current secondary circuit when the secondary circuit is connected to a parasitic circuit to appear a defect, wherein the parasitic phenomenon comprises a homogenous parasitic phenomenon and a heterogeneous parasitic phenomenon; and determining to enter a homogenous parasitic phenomenon processing mode or a heterogeneous parasitic phenomenon processing mode according to the determined parasitic phenomenon of the current secondary circuit, isolating the defected parasitic circuit and restoring normal operation of the secondary circuit. By applying the method and the system, the parasitic phenomenon between the secondary circuits can be rapidly processed, and the normal functions of the secondary circuit are restored.

Description

technical field [0001] The invention relates to the technical field of power system secondary circuit processing, in particular to a method and system for quickly processing secondary circuit parasitic defects. Background technique [0002] In power plants and substations, the electrical part is usually divided into primary and secondary equipment. The electrical circuit that monitors, controls, regulates and protects the primary equipment is called the secondary circuit, and the failure of the secondary circuit often destroys or affects the normal operation of power production. Secondary circuit parasitic refers to the phenomenon of electricity channeling between different secondary circuits, which is a common phenomenon that causes abnormal function of secondary circuits. If there is a parasitic circuit in the secondary circuit wiring, the primary equipment cannot be monitored correctly, and wrong information is provided to the operation and maintenance personnel, making ...
