摘要
晶闸管换流阀采集设备运行回路,是直流输电系统的核心设备,其运行异常所引发的系统故障时有发生。通过对该回路信号的分析与处理监控晶闸管回路的运行状态,实现异常状态的预警,这对直流输电设备的运维管理有着重大的意义。本文提出的嵌入式晶闸管换流阀信号高速采集系统,包括主控模块、光纤信号采集模块和模拟量采集等模块,其可实现对93个通道、最小脉宽达2μs信号运行实时采集,采集频率为100Hz。通过与上位机的通信,完成数据的存储、运行状态的分析、异常预警等功能。
The circuit signal in the operation process of the thyristor converter valve acquisition equipment is the core equipment of the DC transmission system,and the system malfunction caused by its abnormal operation occurs.Through the analysis and processing of the signal to monitor the operation state of the thyristor circuit,the abnormal state of the warning is realized,which is of great significance to the operation and maintenance management of the DC transmission equipment.In this paper,a high-speed signal acquisition system for embedded thyristor converter valve signal is proposed,which includes main control module,optical fiber signal acquisition module and analog acquisition module.It can realize real-time acquisition of 93 channels and minimum pulse width to 2us signal,and the acquisition frequency is 100 Hz.Through the communication with the host computer,the functions of data storage,operation state analysis and abnormal warning are completed.
