分析了一种用于测量电力系统三相电流的光学电流互感器系统,用矩阵光学方法建立了既具有旋光效应又具有线性双折射效应的三相光学电流互感器系统的数学模型.对理论结果进行了仿真实验,指明了线性双折射效应对三相光学电流互感器系统在灵敏度、线性度、稳定性等方面的影响.从而说明,限制系统性能的主要因素是不能避免线性双折射的影响
An optical current transformer system for measuring three-phase current in power system is analyzed, and a mathematic model of three-phase optical current transformer system with both optical rotation effect and linear birefringence effect is established by using matrix optics method. A simulation experiment is conducted to show the influence of linear birefringence on the sensitivity, linearity and stability of the three-phase optical current transformer system, which shows that the main factor that limits system performance is the unavoidable influence of linear birefringence
