Fault Diagnosis Simulation of Light High Voltage Direct Current Transmission System

Light System ◽

Hvdc Light

High Voltage Direct Current (HVDC) system was often the link between major power grids. In order to ensure the safe operation of HVDC, fault diagnosis method was studied. The system structure of HVDC Light system was analyzed, and the normal and fault conditions of the transmission system were simulated in the Matlab platform. This method was very convenient and simple, and it could restore the real situation. The use of simulated waveform could effectively identify the fault types of actual situation, and then it was a flexible, efficient and practical method of fault diagnosis in HVDC Light system.

The reliability of UHVDC (ultra-high voltage direct current) transmission system is significant to the development of power grid. The paper selects dual 12-pulse converters on each pole to model and analyze the UHVDC transmission system. Firstly, the system is divided into six subsystems to evaluate the reliability by the fault tree analysis method. Then based on the fault frequency and the repair time of each subsystems bottom components, the paper calculates the fault frequency and the repair time of each subsystem. Using the frequency and duration method, the paper calculates the fault probability, fault frequency and repair time of the whole system. Finally, it is validated by the actual data of typical lines.
