52、均要接地。(2) 自耦型和有绝缘要求的其它变压器，其中性点必须接地。(3)T 接于线路上的变压器，以不接地运行为宜。(4) 为防止操作过电压，在操作时应临时将变压器中性点接地，操作完毕后再断开，这种情况不按接地运行考虑。1.1.3 线路运行方式选择原则(1) 一个发电厂、变电站线线上接有多条线路，一般考虑选择一条线路检修，另一条线路又故障的方式。(2) 双回路一般不考虑同时停用。1.2 本次设计的具体运行方式的选择电力系统运行方式的变化，直接影响保护的性能。因此，在对继电保护进行整定计算之前，首先应该分析运行方式。现结合本次设计具体说明如下，系统的最大运行方式是所有设备全部投入运行；系统的最小

53、运行方式为发电机 G1或G2y and cutue, a nd tousm, eemets, I gh sa-r ccugtpaly orgta ciy Li u, and ja de are Xa AO, model vlagevice Ciy set has benchmark Four sequal be mote sarig, ccordi nated development of vai sealu-rt - n.投入。对保护501而言，其最大运行方式应该是在系统最大运行方式；保护 501 的最小运行方式应该是在系统的最小运行方式。所有变压器星型侧接地。2故障点的选择和正、负、零序网络的制定如图3.1所示，在整个系统中选择了 4个短路点di、d2、d3、d4。之所以 选这四个点是因为本系统需要零序电流保护， 通过这四点算出最大最小零序电流 为后面的零序电流整定奠定基础。图 3.2、3.3、3.4是d1短路时的正、负、零序网络图，由于篇幅所限，其他短路点的网络图这里没有画出来。.
