摘　　要：提出了一种新的用于潮流及静态电压稳定分析的STATCOM模型。该模型可以考虑STATCOM功率损耗从而可以更准确的计算其有功及无功输出。通过引入两个增广的母线类型,实现了STATCOM的线性PWM控制及相角控制模式及其交流电流极限处理。给出了模型在牛顿潮流及连续潮流中的详细实现。通过IEEE-30及IEEE-300母线系统验证了该模型的有效性,并研究了STATCOM静态损耗、电流极限及控制模式对潮流解及静态电压稳定的影响。This paper presents a novel STATCOM model for power flow and voltage stability analysis. This model can take into account the realistic steady-state losses of STATCOM if desired, and hence more accurately predict the active and reactive power output of it. Furthermore, by introducing two augmented bus types, PWM control and phase control modes of STATCOM are included, and the ac current limit of it can be enforced easily, by which the dimensions of Jacobian matrix can be remarkably decreased. The detailed implementation of such a model in Newton power flow and continuation power flow （CPF） is presented. IEEE 30 and IEEE-300 bus systems are used to verify the effectiveness of the model. The impacts of the control modes, ac current limit, and steady-state losses of STATCOM on power flow and voltage stability are evaluated.
