一种高压直流输电控制系统Profibus现场总线故障诊断方法
摘要：
本发明涉及一种高压直流输电控制系统Profibus现场总线故障诊断方法，包括：S1、提取Profibus现场总线传输的信号；S2、基于S1中所提取到的信号，对高压直流输电控制系统Profibus现场总线故障进行诊断。所述S1中所提取的信号包括Profibus现场总线传输的报文信号和电气信号。所述S1中提取信号的方法为：选取提取报文信号和电气信号的辅助工具；将所选取的辅助工具连接至Profibus现场总线接口和计算机；在计算机内打开所述辅助工具所对应的应用程序，完成所述报文信号和电气信号的提取。使直流输电技术人员能够及时掌握总线网络运行状态并排除设备故障，保障直流输电系统可靠运行。
摘要（英）：

The invention relates to a high voltage dc (direct current) transmission control system Profibus field bus fault diagnosis method, comprising the steps that S1, Profibus field bus transmission signals are extracted; and S2, based on the signals extracted in S1, a high voltage dc transmission control system Profibus field bus fault is diagnosed. The signals extracted in S1 include a Profibus field bus transmission message signal and a Profibus field bus transmission electrical signal. The signal extraction method in S1 comprises the steps that an auxiliary tool for extracting the message signal and the electrical signal is selected; the selected auxiliary tool is connected to a Profibus field bus interface and a computer; the application program corresponding to the auxiliary tool is started in the computer, and the extraction of the message signal and the electrical signal is finished. The dc transmission technical personnel can timely master the running state of a bus network and troubleshoot the equipment fault, so that the dc transmission system is enabled to run reliably.
