【Abstract】 A TCP/IP based digital device to automatically switch the emergency substation power source is developed. Using this device the power source of each substation can be used as the reserve power source for other substations under the serial connection mode of power network. In the hardware of the device the MCS-196 single chip microprocessor system is adopted, including four single chip microprocessors, interface circuits and peripheral power supplies, etc. This device is suitable to 35kV and lower substations and its advantages are simple structure, lower cost and easy to integrate with substation automation system.更多还原
