Design of Distributed Synchronous Data Acquisition System for HVDC Corona Current
In order to collect the corona current in multiple locations of HVDC transmission lines,a distributed synchronous data acquisition system is designed and implemented.The system comprises a time server and a plurality of subsystems,the time server and the client computers in subsystems form a local area network through a switch.The distributed synchronous data acquisition system is designed based on NTP(Network Time Protocol),the Client/Server work mode is used in the system.At regular intervals,the time synchronization between clients and server is executed,the server sends collection command to each subsystem.The synchronization scheme of the corona current measurement system is realized by the software programming of the server and the client,and the synchronization precision can reach 1.725ms,which provides a solution for the large-scale distributed synchronous data acquisition.
