Abstract The energy management system (EMS) is the important part of substation automation system．An embedded energy management system based on the computer network is presented and developed．The system is designed of the embedded processor and the real time operating system(RTOS)．The communication part of the system is based on the TCP/IP protocol via the Ethernet port or embedded modem ．Thus this system has high reliability and good real time performance．The system design，hardware design，software design，and the practical operating results are discussed in detail．
