摘要
随着新能源的大量接入,阻抗分析法在新能源并网次同步振荡中得到了广泛应用,但是针对新能源与火电打捆系统,现有方法在机电耦合的阻抗建模方面仍存在模型适用性问题。为此,提出了一种基于状态空间的阻抗分析法(IMBSM),将电力系统非电气元件耦合到电气元件的动态特性,以导纳函数的形式统一建模。为配合IMBSM的应用,提出了一种新的串联谐振判据,该判据通过拾取源、网子系统的视在谐振点,计算系统的谐振频率。IMBSM不仅包含了系统特征值等关键信息,并且具有比阻抗扫描法更高的精度。最后,基于IEEE次同步振荡第一标准模型及风火打捆经串补送出系统模型,验证了IMBSM及所提串联谐振判据在次同步振荡分析中的准确性和可行性。
        Impedance analysis method has been widely used in the sub-synchronous oscillation of power systems integrated with large scale renewable energy connected to the grid.However,for the renewable energy and thermal power bundled system,the current methods still have adaptability problems in the modeling of electromechanical coupling components.An impedancebased method based on state space models(IMBSM)is proposed to aim at sub-synchronous oscillation studies.The dynamic characteristics of non-electric components coupled to the electrical components are modeled in the form of admittance functions.In order to cooperate with the IMBSM,a new criterion for series resonance is presented,it computes resonance frequency by the apparent resonance points in source and grid subsystem.The IMBSM not only contains eigenvalues,which are vital for system analysis,but also has more accuracy over frequency scan method.In the end,the IEEE first benchmark model is used to demonstrate the accuracy and feasibility,concerning the method and criterion proposed above.
