Abstract:

利用电力系统实时数字仿真系统(real-timedigitalsimulator,RTDS),研究并建立了全光纤电流互感器(fiberopticalcurrenttransformer,FOCT)的实时动态仿真模型。通过对FOCT检测系统中偏差与反馈2部分的合理简化,建立了等效的数字闭环控制系统模型;根据不同温度下,光纤Verdet常数和λ/4波片相位延迟的变化规律,以及探测器接收光强关于λ/4波片参数的数学模型,将可变的温度参数引入到了模型中。通过仿真试验,找到了能够补偿温度误差的λ/4波片初始相位延迟角的范围,证明了所建FOCT实时动态仿真模型是合理的,能够有效模拟FOCT的稳态温度特性,且暂态特性良好,可用于对FOCT性能的深入研究及智能变电站相关设备的测试。
