摘要
光学电子式电压互感器的暂态特性需要深入研究以保证继电保护等自动化设备的正确运行,并促进新的保护原理的应用。在理论分析光学电压互感器数学传感模型的基础上建立了一套暂态仿真系统,探究了在一次侧不同相角下的短路和带滞留电荷重合闸暂态过程中,影响光学电压互感器暂态特性的相关因素及影响度。建立了一套光学电压互感器暂态特性测试系统,研制了测试系统硬件平台和功能软件,对实际的光学电压互感器产品进行了暂态测试,为光学电压互感器的工程应用提供了一套实用的检测手段。
Transient characteristics of optical voltage transformer need the in-depth study to ensure the proper opera- tion of automation equipment, such as relay protection, and to promote the application of new protection principle. Based on the theoretical analysis of mathematical sensing model of optical voltage transformer, a set of transient simu- lation system is established. To explore the short circuit at different angles and with trapped charges of reclosing tran- sient process, factors related to optical voltage transformer transient characteristics and effects. A set of transient char- acteristic test system of optical voltage transformer is established, including hardware platform and application soft- ware. Transient test of the actual optical voltage transformer product is conducted, which provides a set of practical detection method for engineering application of optical voltage transformer.
