Abstract
The features and design of real time database server for real time supervision of power system are introduced,several key techniques of which are analyzed,such as multi-thread,OCI (Oracle Call Interface),Socket and select function.The communication protocol adopts TCP with connection,the software design applies blocking mode and OCI technique,and the function SELECT()is used to disrupt the blocking for error redundant processing.Site test proves that this design meets the demand of phase angle measuring system for real-time data processing.
