Abstract

The invention provides a method for simulating cable failure location by using a bridge method. The method comprises the following steps: building a three-dimensional cable model by using a virtual reality technology, and building a cable core resistance distribution model according to operation parameters of a tested cable; making a virtual three-dimensional shell of a bridge of a cable failure locator by using the virtual reality technology, and setting a three-dimensional key and a three-dimensional dial on the three-dimensional shell; responding to an instruction input by a user through the three-dimensional key, carrying out a failure location simulated test upon a tested cable by using the bridge method; calculating proportion value of resistors of the bridge according to the cable core resistance distribution model, and displaying the proportion value on the three-dimensional dial; calculating a failure spot of the cable according to the proportion value, and displaying the failure spot at a corresponding position on the cable three-dimensional model. With the adoption of the method for simulating the cable failure location disclosed by the invention, visible simulation of cable failure location is realized, important direct reference for removal of cable failure is provided, the safety of power supply is ensured, the efficiency of security work is improved; and the method has very high promotion value.

Description

technical field [0001] The invention relates to power system simulation technology, in particular to a cable fault location simulation method based on an electric bridge method. Background technique [0002] Cables are a key piece of equipment for transporting electricity in large urban power grids. The occurrence of unqualified insulation defects during cable operation will cause the possibility that the cable cannot transmit power normally and cause large-scale power outages. Cable fault location is an important means for power system cable-related technology research, operation defect detection, and condition-based maintenance. [0003] There are many methods for cable fault location, among which the bridge method is one of them. The bridge method uses the cable core resistance and proportional resistance on both sides of the fault point to form a Murray bridge. According to the characteristic that the resistance is proportional to the cable length Perform fault locatio...
