摘要
开发了一套完整的电力系统自动定相装置。分析了二次定相法并对其进行改进,设计了自动定相装置的软硬件,对现有的定相工作管理流程进行优化。应用结果表明,该装置可提高电压互感器二次定相的效率及可靠性。
An integrated power system auto-phase identification device was developed. The method of secondary phase identification was analyzed and improvement. The hardware and software of the device were designed, and the existing flow of phase identification was optimized. The application results showed that the device could im- prove effect and reliability of VT＇ s secondary phase identification.
