摘　　要：基于TCP／IP以太网通信技术研制了数字式网络备用电源自投装置,在串联接线的电网接线方式下能实现多座变电站间的电源互为备用。该自投装置的硬件采用MCS-196单片机系统,由4个单片机及外围电源、接口电路组成。该装置价格低、结构简单通用、易接入变电站综合自动化系统,适用于35kV及以下等级电网。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.
