Research Of Single-Board Prime Machine System In Distribution Automation

With the demand for high quality of electric energy is increasing,as the mostimmediate part to the consumer,distribution network'S efficient and reliableoperation is very important．As the result,new distribution automation equipmentwith high performance is inevitable．Prime machine system,as data collectionand processing subsystem of DMS,provides communication of kinds ofinformation between control center and RTUs．It'S reliability,real—time abilitvand stability affect the SCADA system directly．To solve the disadvantage of theexisting system,whose channels are dependent,a new proj ect of single board system is brought forward and its hardware and software are designed．With highperformance chip of communication,independence of channels is realized．Basicfunction of system is realized,and faster reposition and expansibility of the single chip is fully applied．...
