以风电为代表的新能源电源经远距离交流输电线路,将清洁能源送往用电负荷中心。弱电网下并网直驱风电机组可能因其网侧换流器和锁相环动态交互发生宽频振荡失稳风险。为提升直驱风电机组在极弱电网下的宽频振荡稳定性,首先推导考虑直流电压和交流电流时间尺度的并网直驱风电机组全阶框图模型。然后,综合考虑直流电压以及交流电流两种时间尺度,提出了弱电网条件下网侧换流器和锁相环矢量控制系统以及同型直驱风电场的参数整定原则,使得并网直驱风电机组在短路比大于1的条件下始终保持稳定运行。最后结合单台直驱风电机、同型直驱风电机组并网系统实例,通过特征值分析法和非线性仿真对所提控制参数整定方法的有效性进行验证。
Renewable energy power sources

deliver clean energy to load centers via long-distance AC transmission lines. The dynamic interaction between grid-side converters and phase-locked loops may lead to wide-frequency oscillation instability for grid-connected direct-drive wind turbines in extremely weak grid. To improve the stability of wide-frequency oscillations of permanent magnet synchronous generators in extremely weak grid
in this paper we firstly derive a full-order block diagram model of grid-connected PMSG considering the time scales of DC voltage and AC current control. Subsequently
the principle of parameter tuning of grid-side converter and phase-locked loop vector control system in extremely weak grid conditions is proposed
considering the time scales of DC voltage and AC current. As a result
the grid-connected PMSG can always maintain stable operation under the condition that the short-circuit ratio exceeds 1. Finally
the effectiveness of the proposed control parameter tuning method is verified through eigenvalue analysis and nonlinear simulation with an exampled single grid-connected PMSG system.
