Small Disturbance Stability Limit Dynamically Dominated by Phase-Locked Loop of Doubly-Fed Wind Turbine
针对锁相环动态主导的并网双馈风电场小干扰稳定性问题,提出了一种双馈风电场小干扰失稳的判定方法.首先建立了单台双馈风机二阶线性化模型,其次根据单机等值模型将推导的二阶线性化模型推广至并网双馈风电场.最后依据劳斯-赫尔维茨定理(the Rausch-Hurwitz theorem)推导出锁相环动态主导的并网双馈风电场小干扰稳定极限,解释了风机有功出力、电网连接强度、锁相环控制参数及风机数量对锁相环动态主导的并网双馈风电场小干扰稳定的影响规律及内在机理…查看全部>>
Aiming at the problem of small disturbance stability of grid-connected doubly-fed wind farms dynamically dominated by phase-locked loop,a method for determining small disturbance instability of doubly-fed wind farms is proposed.Firstly,a second-order linearization model of a single doubly-fed wind turbine is established.Secondly,the derived second-order linearization model is extended to grid-connected doubly-fed wind farms based on the single-machine equiva…查看全部>>
