Research On Cable Fault Detection Methods Of Daqing Oilfield Based On Traveling Wave

With the further development of Daqing oilfield and sustainable development, Power network is more and more perfect covering oilfield, cable in the totalline length ratio is increasing year by year, the cable buried in the ground, when the power cable faults affect the normal power supply, cable fault finding difficulties, Increased the impact of power of oil production. This subject comes from the Daqing oil field electricpower cable operation and maintenance management in the process of practical problems. At present, a variety of power cable detection technology, in accordance with the cable running situation of Daqing oil field, what should use the principle of detecting technology in Daqing oilfield, the environment,whether the detection technology of typical need for adaptive parameter adjustment are going to study in this paper.This paper analyses the basic principle and application of power cable fault detection technology, starting from the origin and classification of power cable fault, expounds the principle of voltage, current traveling wave in the cable line, Based on the analysis of a fault location technique based on the theory of traveling wave fault location, in determining the detection method in Daqing oilfield cable fault at the same time, also in view of the present situation and parameter of the oil field operation of cables, calculate the key parameters of cable fault location, To find out the suitable for Daqing oil field power system characteristics, 35 k V the following at all levels of power cable fault detection at lightning pressure limit, for the reasonable selection of parameters detection system provides an important reference set, Employees can quickly and accurately locate to the point of failure, while reducing the impact on the test cable, extension cable service life, improve the management level of power grid operation and maintenance.
