摘　　要：新投变电站和新投线路时,必须要进行相关试验,试验验证正确后,才可投入电力系统运行。介绍一次定相、一次核相、异源二次核相试验的方法,可验证电力系统一次系统接线的正确性;介绍同源二次核相试验的方法,可验证电压二次回路接线的正确性。针对线路间隔新投、两卷变压器主变压器新投、三卷变压器主变压器新投、牵引站出线新投的情况,需进行二次回路保护测相量工作,画出正确的相量图,以此验证相关的电流回路接线正确性。通过该方法验证新投设备是否符合投运的要求。When new substations and lines are put into operation,relevant tests must be carried out,and the power system can be put into operation only after the test being verified correct.It introduces the methods of primary phasing,primary nuclear phase and heterogenous secondary nuclear phase tests,which can verify the correctness of the primary system wiring of the power system.The method of homologous secondary nuclear phase test is introduced,which can verify the correctness of voltage secondary circuit wiring.In view of the new operation of the line interval,the new operation of the main transformer of the two winding transformer,the new operation of the main transformer of the three winding transformer and the new operation of the outgoing line of the traction station,the phasor measurement of the secondary circuit protection need to be carried out.The correct phasor diagram is drawn to verify the correctness of the relevant current circuit wiring.Through the method verifying,whether or not the new equipment meets the requirements of operation.
