摘要
高压断路器关系到电力系统的安全运行,对断路器状态进行在线监测有助于提高系统的可靠性.首先给出断路器故障诊断所需监测的项目,根据这些监测项目,提出了一种基于DSP和CPLD的断路器在线监测系统,然后具体分析了断路器各状态参数的检测方法及采用的传感器、DSP、A/D转换器、CPLD、通信接口等系统各环节的工作原理及作用.利用系统中DSP强大的信号处理功能,完成复杂的故障诊断运算,为断路器状态监测提供较好的硬件平台.
High voltage breaker plays an important role in the security of an electric power system. Online monitoring of high voltage breaker helps improve the system reliability. In this paper items to be monitored are first introduced, and then based on DSP and CPLD, a system which can monitor these items online is given, The principles and functions of each part of the system such as the sensors, DSP, A/D converter, multiplexer, CPLD, communication port etc. are described in detail, Owing to its capability of signal processing, the DSP in the system can accomplish complex failure diagnosis, thus it provides a good hardware platform for online monitoring of the operation of high voltage breaker.
