摘要:
阻容网络理论根据避雷器实际结构和具体的设备配置建模,对避雷器传统的三相单节对称相间干扰分析模型作出了较大改进,但未总结具体建模的合理性。基于避雷器阻容网络理论,选择500 kV智能变电站三相避雷器系统建立3种阻容网络进行仿真分析。总结阻容网络仿真结果与所选择模型(导体数量)的变化规律,与监测数据结合,讨论阻容网络建模合理性。结果表明,典型500 kV智能变电站三相避雷器系统的阻容网络,避雷器需分节,需考虑相邻电压互感器及上端水平母线等影响,仿真结果才能与现场监测数据有更好的一致性。进而根据最合理的阻容网络模型对监测数据进行分析计算,诊断避雷器状态。
Abstract:
On the basis of the actual structure of the lightning arrester and the specific equipment configuration, the theory of the resistance capacitance network has made a great improvement on the traditional three-phase single node symmetric Interphase Interference Analysis Model of the lightning arrester, but it does not sum up the rationality of the concrete modeling.Based on the theory of arrester resistance capacity network, this paper chooses three phase arrester system of 500 kV intelligent substation to build three kinds of resistance capacitance network for simulation analysis. The change rules of resistance capacitance network and the selected model(conductor quantity)are summarized and combined with monitoring data. The rationality of capacitive resistance network modeling is discussed. The results show that the resistance capacitance network of the typical 500 kV intelligent substation three-phase lightning arrester system, the lightning arrester needs to be segmented, the influence of the adjacent voltage transformer and the upper level bus line should be considered, and the simulation results can be better consistent with the field monitoring data. Then, according to the most reasonable resistance capacitance network model, the monitoring data are analyzed and calculated to diagnose the state of arrester.
