摘　　要：输电线路电流保护和电压保护分别作为电力系统保护原理和手段之一,是十分重要的保护类型。该设计分别对电力线路的过压、欠压以及过流进行实时的监测与控制。同时采用相间短路的电流/电压保护和接地短路的零序电流/电压保护。这里利用计算机的高速处理能力性能,达到了对输电线路进行复杂多方式监测,复杂多方式控制与保护的目的。Curren protection and voltage protection in transmission line as one method and principle of electric power system,they are very important protection. The overvoltage, undervoltage and overcurrent of transmission line are controlled and monitored in real- time by the design. At the same time,the current and voltage protection of phase- to- phase short circuit, and zero sequence current/voltage protection of ground short circuit are both adopted. Using high processing of computers, the complex multi- mode monitoring, control and protection for transmission line are realized.
