针对大规模储能变流器(PCS)并网引发的宽频振荡问题,现有振荡抑制策略未能有效抑制由频率耦合效应造成的多频段谐振。在考虑由锁相环等非线性环节引发的振荡频率耦合特性的基础上,文中提出了一种改进的自适应有源阻尼谐振抑制方法。首先,基于实际电网的复杂拓扑结构,建立PCS并网系统模型,并根据Nyquist稳定判据揭示了互联系统的振荡风险区域。然后,在设计级联陷波器环节时进一步考虑锁相环控制引发的频率耦合效应,并通过实时量测PCS与电网之间的电流、电压信息设置并修正陷波器参数,使得PCS在全频段尽可能提供正阻尼,即相角位于±90°之间,从而适应电网复杂多变的运行方式,实现PCS并网系统的振荡自适应抑制。与现有方法相比,所提方法降低了谐振频率转移的风险。最后,通过PSCAD/EMTDC仿真以及实机实验验证了所提控制方法具有更好的动态性能及谐波抑制效果。
Aiming at the wide-band oscillation issues caused by the large-scale grid-connected power conversion system (PCS)
the existing oscillation suppression strategies have failed to effectively suppress the multi-band resonances caused by the frequency coupling effects. Considering oscillation frequency coupling characteristics induced by nonlinear links such as the phase-locked loop (PLL)
this paper proposes an improved adaptive active damping resonance suppression method. First
based on the complex topology of actual power grids
a PCS grid-connected system model is established
and the oscillation risk areas of the interconnected system are identified according to the Nyquist stability criterion. Then
during the design of the cascaded trap stage
the frequency coupling effect caused by PLL control is further considered. By real-time measurement of current and voltage information between the PCS and the power grid
the trap parameters are set and adjusted
enabling the PCS to provide positive damping across the entire frequency band
i.e.
with the phase angle within ±90°
thus adapting to the complex and variable operation conditions of the power grid and achieving adaptive oscillation suppression in the PCS grid-connected system. Compared to the existing methods
the proposed method reduces the risk of resonance frequency shift. Finally
simulations using PSCAD/EMTDC and practical experiments validate that the proposed control method offers better dynamic performance and harmonic suppression effect.
