描述了最近开发的采用负序电流进行远程后备保护的数字距离继电器的配置和性能。由于远方后备保护继电器是针对远方故障而设计的，受电流分布因素的影响，输入继电器的故障电流较小。这反过来又使继电器对负载电流的影响敏感。为了解决这个问题，采用负序电流的距离继电器被开发出来并投入使用。该继电器的特点是：（1）负载电流的影响减小，故障时继电器很少因负载电流而误动作； (2)对负分量进行计算的数字继电器的硬件配置简单，相对无误差。 >
The configuration and performance of a recently developed digital distance relay using negative sequence current for remote backup protection are described. Since relays for remote backup protection are designed for remote faults, the fault current that is input to the relay is small due to the influence of current distribution factors. This in turn makes the relay sensitive to the effects of load current. In order to resolve this problem, a distance relay using negative-sequence current has been developed and put into use. The characteristics of this relay are: (1) the effects of load current are reduced, so the relay rarely maloperated due to load current during a fault; and (2) the hardware configuration of a digital relay that performs calculation on a negative component is simple and thus relatively error-free. >
