电压源换流器-高压直流（VSC-HVDC）的商业装置现在作为异步链路和水下/地下直流输电投入使用。本文的研究旨在为VSC-HVDC提供同步功率和阻尼功率，以便在暂态之后，在最短的时间内达到稳态。阻尼功率是通过注入增量功率来实现的，增量功率与锁相环测量的频率偏差成比例。同步功率通过以下方式实现：1）在功率测量中引入延迟，以及2）通过在VSC站中结合静态同步串联补偿。通过对一个接入VSC-HVDC的汽轮发电机系统的数字仿真，证明了同步和阻尼功率的有效性。结果表明，与同步功率和阻尼功率，从故障扰动的恢复是非常快的。
Commercial installations of voltage-source converter-high voltage direct current (VSC-HVDC) are now in service as asynchronous link and as underwater/underground dc transmission. The research reported in this paper is directed to providing VSC-HVDC with synchronizing power and damping power so that after a transient, the steady-state is reached in minimal time. Damping power is achieved by injecting incremental power which is proportional to the frequency deviation measured by a phase lock loop. Synchronizing power is achieved by: 1) introducing a delay in the power measurement and 2) by incorporating a static synchronous series compensation in the VSC-station. The effectiveness of both the synchronizing and damping power is demonstrated through digital simulations of a turbine-generator system which is connected to a VSC-HVDC Station. It is shown that with the synchronizing power and damping power, recovery from the fault disturbance is very much faster.
