基于信号特征的在线故障分析和智能诊断研究

摘要

The Petri network automatic fault diagnosis technology based on signal characteristic is studied. The switch telecommunicating displacement, SOE information, protection signal and soft message information are through online acqui- sition. Through logical, systematical and effectuation analysis, the functions of power grid online analysis, identification and intelligent diagnosis are implemented.%研究开发基于电网故障信号特征自动生成电网故障诊断Petri网络的技术。通过在线获取调控一体系统的开关遥信变位、SOE信息、保护动作信号和微机保护软报文信息,对信号综合进行逻辑化、条理化、有效化分析,实现电网故障在线分析、辨识和智能诊断。
