Abstract：The new generation of large-scale condenser is widely used in the construction of ultra high voltage power grid due to its two-way and fast dynamic reactive power regulation ability. As an important part of large-scale condenser, the reliable and stable operation of lubricating oil system is very important. In view of the problems such as abnormal oil supply pressure in the actual operation of large-scale condenser lubricating oil system, it seriously threatens the stability of system operation. This paper puts forward a method to improve it by accumulator. Through in-depth analysis of the problems existing in the configuration of the current lubricating oil system, the basic principle structure and selection calculation of the accumulator are described. Taking the actual converter station as a column, the installation of accumulator can greatly improve the reliability of the lubricating oil system of the large-scale condenser, enhance the reliability of the system improve the operation stability and avoid the risk of tripping through field test and comparative analysis, thus providing important reference value for engineering application.
