Abstract

The invention relates to an online state monitoring system for series compensation device, comprising a series compensation state monitoring information integration platform, a series compensation platform power supply, a spark gap state monitoring subsystem, a voltage limiter state monitoring subsystem and a capacitor bank state monitoring subsystem. The technical solution provided by the invention helps to timely discover and eliminate the threat posed by the safe and stable operation of the power grid due to the deterioration of the equipment state, and ensures the safe, stable and reliablepower supply of the power grid.

Description

technical field [0001] The invention relates to the field of an online monitoring system for the state of an ultra-ultra-high voltage series compensation device, in particular to an online monitoring system for the state of a series compensation device. Background technique [0002] At present, some ultra-high voltage series compensation devices put into operation in China have been in continuous operation for many years. Although the overall operation is stable, there have been many cases of oil leakage or bursting of capacitors, false triggering of spark gaps, and metal oxide voltage limiters (referred to as voltage limiters). Faults such as the pressure release of the device MOV) and the damage and misoperation of the control and protection equipment lead to the withdrawal of the series compensation, which affects the safe and stable operation of the power grid and causes the loss of transmission capacity. In the 500kV series compensation project that has been put into op...
