| Abstract: | The energy management system!(EMS) of Guangdong Provincial Dispatching Center adopts a new type front--endcommunication system. Its hardware design has a characteristic of double equipment. including double computers. doublepower sources, double satellite clocks and double Ethernets. Another feature of its front--end system is to change thecommonly used double (main and reserve) front--end computers switching mode to the new double channels switching mode byonly switching the fault communication port mutually. The front--end system also has some characteristics on its linkingmodes of the double channels, supporting the party--line communication of multiple protocols and synchronous/asynchronousmodes. and acquiring the power energy by dialing telephone and so on. |
