The Application of ATCA Structure for Power Communication Switching System

In order to meet the needs of the power communication device This paper discusses the key technologies of the power switching equipment based on ATCA structure, including network topology selection and rack management system, as well as a system performance test result is given. The test results show that the power switching equipment based on ATCA structure has good rack management ability, and it can monitor and adjust parameters such as system temperature. It can realize hot backup of the system, making the system with high reliability and high transmission bandwidth. I. INTRUCTION Power communication network comes into being in order to guarantee the safe and stable operation of the power system, and it is base of building smart grid. With future grid dispatching automation, network operators, market-oriented, and management of modern development, power communication network is a more important mean to ensure grid security, stability and economic operation, and it is the critical infrastructure of the power system. The future smart grid puts forward higher requirements for power communication network reliability, transmission bandwidth, flexibility and anti-disaster. Power communication network transmission services include the following four points: 1) Transmission of smart electricity transmission information, including line status, tower status, weather condition.
