[Abstract]:Power cable has a wide range of applications, involving power, construction, communications, manufacturing and other power supply and auxiliary systems, closely related to national economic development and people's lives. In order to improve the operational reliability of the power system. It is an important problem of power system to reduce the occurrence of power failure and obtain the operation state and fault information of power cable timely and accurately. It is also the basic guarantee to improve the reliability and safety of power supply. As the mainstream product of high-voltage cable, XLPE cable has been more and more widely used. In order to realize the on-line operation monitoring of XLPE cable, understand the potential hidden trouble in operation in time, and master the running state of equipment. Therefore, the corresponding measures can be taken to reduce the power network accidents caused by sudden situation and improve the reliability of power supply. Aiming at the partial discharge problem of XLPE cable, the on-line monitoring system of running cable is built. Application in practical engineering. The main research work includes: 1) on the basis of investigating various defects that may exist in the production, installation and operation of XLPE cables, the typical types of defects in actual production are determined. The typical fault of XLPE cable is simulated and the typical defect model is made. 2) based on the partial discharge detection circuit model, the cable line detection system is built, and the various typical cable fault models are tested in laboratory to verify the correctness of the local discharge acquisition circuit. The whole construction of on-line monitoring system for XLPE cable is carried out. The concrete work includes the collection of partial discharge signal of the cable, the selection and construction of transmission circuit; The application and working standard of XLPE cable distributed optical fiber temperature measurement system; The function of background monitoring software for XLPE cable multi-parameter on-line monitoring system is analyzed, and the corresponding monitoring software is developed. The real engineering construction of 220 kV HV cable on-line monitoring system is carried out. A real-time on-line monitoring system with partial discharge and operating temperature is built, and the remote access and monitoring of monitoring data are realized. It provides technical guarantee for real-time analysis of cable running state.
