Description

Technical field [0001] The invention relates to the field of power grid transmission line control, in particular to an online partial discharge monitoring method and system. Background technique [0002] The safety of equipment is the foundation for the safe, reliable, and stable operation of the power grid. Effective and accurate monitoring and diagnosis of equipment is an important way to improve the reliability of power supply and the intelligent level of grid operation. [0003] Partial discharge is a common phenomenon in the operation of power equipment, and the monitoring of partial discharge can be prepared to reflect the operation of the power equipment. Partial discharge monitoring involves many equipment monitoring manufacturers and equipment types. How to model the PD monitoring data in a unified manner is the information basis for the unified monitoring and management of the primary and secondary equipment of the power system. [0004] Because the equipment involved in p...
