摘　　要：用AREVA公司的Micom P140系列数字继电器,实现了实用化配电线路无通道保护.介绍了该保护的硬件结构以及软件实现过程.大量的实时数字仿真（RTDS）试验结果表明,该保护用于单断路器的配电线路中,能够实现不对称故障快速有选择性的从两端切除,从而为尽快恢复对健全线路的继续供电提供了必要的条件.这对进一步推进配电线路无通道保护的实用化和配电自动化的实现具有重要意义.Based on the principle of practical non-communication protection for distribution feeders, the function is implemented using Micom P140 series numerical relays manufactured by AREVA T＆D Ltd. Company. This paper presents the hardware and software structures of the relay. A great deal of RTDS （real time digital simulator） testing results show that the relays can remove the fault fast and selectively from both ends in single circuit breaker distribution feeders so that it＇s possible to restore the power supply to the healthy lines. This is very significant to both the more practical application of non-communication protection for distribution feeders and the realization of distribution automation.
