摘要
通过分析南方电网的区域功率振荡模式以及对采用不同直流调制方式的系统进行时域仿真,设计了可以有效抑制南方电网内区域功率振荡的直流调制控制器,并将其应用于贵广直流工程中,从而提高了南方电网交直流并联系统运行的稳定性。
By means of analyzing regional power oscillation modes in Southern China power grid and simulating the systems which adopt different HVDC modulation modes, an HVDC modulation controller which can effectively suppress the regional power oscillation within Southern China power grid is designed and is applied to HVDC system from Guizhou to Guangdong, thereby the stability of AC/DC hybrid system in Southern China power grid will be improved.
