摘要
针对单调谐与失谐滤波器在参数设计选型、设备结构设计、安装以及运行等环节存在诸多问题,本文提出了一种该类装置运行状态测量与评价方法。论文首先简单介绍了单调谐与失谐滤波器的电路原理及阻抗频率特性,接着对测点进行设置,采用该测量方法测量计算单调谐与失谐滤波器运行参数并进行运行状态分析,最后通过测试实际案例、计算运行参数、搭建系统谐波阻抗模型以及谐波电流系数仿真,对单调谐滤波器串联谐振点的偏移程度、并联谐振峰的大小、过电压、过电流及过容量等运行状态进行分析,以期对装置的优化改造和安全预警提供技术支撑。

Finally,such operation state as the bias degree of series resonance point,peak magnitude of parallel resonance,overvoltage,over current and over capacity of the single tuned filter is analyzed by way of measuring actual case,calculating operation parameters,setting up system harmonic impedance model and tuning harmonic current coefficient simulation,so to provide technical support for the optimization innovation and safe precaution for the device.
