构网型储能与调相机的暂态过电压抑制能力对比研究
Comparison of transient overvoltage suppression capability of grid-forming con-verter and synchronous condenser
摘要
Abstract
When faults such as blocking and commutation failure occur in a high-voltage direct current(HVDC)transmission system,they can cause transient voltage fluctuations near the sending-side converter station and lead to the disconnection with power grid.Firstly,the operating principles,response characteristics,and key parameter in-fluences of the grid-forming energy storage open-loop control strategy are analyzed.Then,the reactive response char-acteristics of the synchronous condenser are analyzed,and a comparison is made between the grid-forming energy storage reactive power control model and the excitation regulation control model.Finally,a semi-physical simulation system is established,including EHVDC,photovoltaics,synchronous condenser,and grid-forming energy storage,to conduct comparative experiments on the effect of suppressing AC transient overvoltage under DC commutation failure.The results indicate that grid-forming energy storage and distributed synchronous condenser with the same capacity can achieve similar effects in terms of reactive transient response speed and the ability to suppress AC tran-sient overvoltage.关键词
