利用直流附加控制方式，即直流双侧频率调制和直流有功功率调制方式来增强系统的稳定性。通过直流线路的闭锁故障和500 kV交流线路的故障对比，分析得出采取多直流协同调制、直流调制与稳控装置的配合方式能增强系统的暂态稳定，并可减少系统故障后稳控装置的切机量，提高电网的经济效益。

a method that using DC added control mode,i?e? DC two sides frequency modulation and DC active power modulation,to enhance the system stability is proposed? through the comparison of power grid under 500 kV AC faults and DC blocking faults, a conclude is reached that Coordination control among multi-DC coordination modulation,DC modulation and stability control equip-ment can enhance the system transient stability,reduce generation shedding quantity and raise the economy benefit of power grid.
