    摘 要:要實現(xiàn)高壓直流輸電線路的安全穩(wěn)定運行需要為其提供充足的無功功率。提出將同步調(diào)相機配置在高壓直流輸電線路換流站中,對其進行無功補償以提升擾動或者故障時高壓直流輸電線路的逆變側(cè)交流電壓?;赑SCAD/EMTDC軟件搭建了同步調(diào)相機與高壓直流輸電線路模型,對同步調(diào)相機的無功補償能力進行仿真分析,并針對同步調(diào)相機補償過程中出現(xiàn)的電壓波動不能立即平穩(wěn)的問題,提出一種針對同步調(diào)相機的勵磁機的優(yōu)化控制策略,實現(xiàn)了電壓的快速穩(wěn)定。

    Abstract: To achieve the safe and stable operation of high voltage direct current(HVDC) transmission lines, it is necessary to provide sufficient reactive power for them. This paper proposed that the synchronous compensator was put into the converter station of HVDC transmission lineand reactive power compensation was used to improve the AC voltage at inverter side of the HVDC transmission line when the disturbance or fault occurred.The synchronous compensator and HVDC transmission line modelswere built based on PSCAD/EMTDC,and the reactive power compensation capability of synchronous camera was carried out simulated analysis.Aiming at the problem that the voltage fluctuation in the compensation process of synchronous compensator can’t be immediately smooth, an optimal control strategy of synchronous generator is proposed to realize the fast and stable voltage.
    Key words: high voltage direct current transmission; synchronous compensator (SC); disturbances; voltage stability control
