摘　　要：智能终端是智能变电站自动化系统过程层的重要设备。选相控制技术是解决高压断路器投切负载瞬时电磁效应的有效措施。本文将二者有机融合,提出了一种具有选相控制功能的智能终端的实现方案。简单介绍了选相控制技术的基本原理,对所提方案设计需求进行了简要分析,并对该方案主要部分的实现进行了深入研究和详细阐述。通过对样机试验验证,该新型智能终端既能作为常规智能终端使用,又能提供良好的选相控制功能,具有较强的实用性。Intelligent terminal is a primary process device in digitalized substation automation system. Phase-controlled switching is an effective means to instantaneous electromagnetic effect in switching the power loads with high voltage circuit breakers. A combined realization scheme of intelligent terminal with phase-controlled switching function is proposed. The basic principle of phase-controlled switching is briefly introduced. Then design requirement is succinctly analyzed, and the main parts of the scheme are researched deeply and explained in detail. Depending on the experimentation of pre-industrial prototype, the new device has high practicability. It can not only used as the normal intelligent terminal, but also provides favorable phase-controlled switching function.
