为了研究安装于电网的静止无功补偿器特性及其对电网的影响,需要对SVC进行建模并进行电磁暂态仿真,为了达到电磁暂态研究的有效性,需要建立和实际SVC设备高度一致的仿真模型。通过实际案例介绍了通过ATP仿真软件建立和实际SVC设备高度一致模型的方法,对于应用于电网的SVC的控制方法及建模方法进行了详细的阐述,详细介绍了低电压控制、自适应增益、通过线性拟合求解触发角等功能和方法。并将所建ATP模型的仿真结果和实际装置的RTDS(real time digital power system)仿真结果进行了对比,结果表明二者的波形非常接近,表明所建ATP模型能够充分反映SVC的实际特性,对于通过ATP仿真软件进行电磁暂态研究提供了有效和可信的手段。

For studying the feature of static var compensator(SVC)installing in the power grid and its influence on the power grid,it’s necessary to model the SVC and perform electromagnetic transient simulation.The simulation which is high identical to the real SVC equipment is needed with purpose of studying the effectiveness of electromagnetic transients.The method which is high identical to the real SVC equipment is set up by ATP(alternative transients program)simulation software is introduced through an actual case.The control and modeling method of SVC for the grid is described in detail.Such functions and methods as low voltage control,adaptive gain and firing angle by linear fitting are introduced in detail.The simulation results of the built ATP model and that of RTDS(real time digital power system)of actual device are compared,showing the waveforms of both are very close.It is shown that the built ATP model can fully reflect the characteristics of actual SVC and provide effective and credible means for the study of electromagnetic transient through ATP software.
