摘 要
电能是现代社会中最重要，也是最方便的能源。电能具有许多优点，它可以方便地转化为别种形式的能，它的输送和分配易于实现；它的应用规模也很灵活。
电力系统正常运行的破坏多半是由短路故障引起的。发生短路时，系统从一种状态剧变到另一种状态，并伴随产生复杂的暂态现象。所谓短路，是指一切不正常的相与相之间或相与地发生通路的情况。
本设计主要解决了，K点发生a相接地短路和b、c两相短路时故障点电流；b.求K点发生a相接地短路和b、c两相短路时发电机G和系统c分别提供的故障电流(假设故障前线路中没有电流)。

关键词：两相短路 故障点 单相接地 故障电流

Summary Electricity is the most important in modern society, is the most convenient source of energy. Power has many advantages, it can easily be converted into other forms of energy, its transmission and distribution is easy to achieve; it's also very flexible. Power system up and running most of the damage was caused by a short circuit. When a short circuit occurs, the system changes from one State to another State, and have a complex with transient phenomena. So-called short circuit, refers to all the normal phase and phase or between phase and Earth pathways. The design of the main settlement, k-a-phase short-circuit and two-phase short circuit fault current b, c; b. k-phase earthing short circuit a and b and c two-phase short circuit fault current of the generator system c and g respectively (assuming that failed in the first line there is no current).Key words: two-phase short circuit fault single phase to ground fault currents

The electric energy is the most important and the most convenient energy in modern society. Power has many advantages, which can be easily converted into other forms of energy, its transmission and distribution is easy to achieve; it is also very flexible application. The destruction of the normal operation of the power system is mostly caused by short circuit faults. When a short circuit occurs, the system changes from one state to another, and is accompanied by a complex transient phenomenon. The so-called short, refers to the occurrence or pathway and all abnormal phase condition. The design mainly solves the problem that the K point occurs when the a phase short circuit and the fault point current of B and C two phase short circuit; B.For the K point of the occurrence of a phase and phase, C and B two-phase short circuit when the generator C and system G are provided by the fault current (assuming the fault before the line without current). Keywords: fault point
