建立准确高效的静止同步补偿器（STATCOM）数学模型是电力系统动态无功补偿研究的重要基础。电力电子开关器件的应用使得STATCOM模型超出了准稳态的假定，传统的正弦稳态模型难以满足仿真速度和精度兼顾的要求。针对这一问题，将动态相量法引入到 STATCOM建模中，在数学模型基础上推导了对应动态相量模型，利用MATLAB对所提模型进行了测试。结果表明动态相量模型能快速准确反映STATCOM的动态无功补偿特性，为含STATCOM装置的大型电力系统仿真提供了有力支持。%Establish an accurate and efficient static synchronous compensator (STATCOM) mathematical model is an important foundation for power system dynamic reactive power compensation research. Application of power electronic switching devices makes STATCOM model beyond the assumed quasi-steady state, the traditional sinusoidal steady state simulation model can not meet the requirements of both speed and accuracy. To this problem, introduces dynamic phasor method to STATCOM modeling, corresponding dynamic phasor model is derived based on mathematical model , the proposed model is tested using MATLAB. The results show that dynamic phasor model can quickly and accurately reflects the characteristics of dynamic reactive power compensation STATCOM, provides strong support for large-scale power systems simulation with STATCOM device.
