本文详细介绍了电力系统中两进线备投逻辑的具体实现方式，包括主供电和备用供电的不同状态判断与切换条件。通过逻辑表达式阐述了如何在主供失效时平滑过渡到备供状态。

1# 主供：

VL1= NOT PVTS_1_3
V1 = VL1 AND P59_1_7 AND P59_1_8 AND P59_1_9
VL2 = VL1 AND I12 AND I21 AND I14 AND I26 AND I24
VL3 = TON(VL2 ,5000 )
V2 = VL3
VL4 = TOF(VL2 ,4000 )
VL5 =P50/51_1_3 AND P50/51_2_3
VL6 =NOT VL5
VL7 = P27/27S_1_3 AND VL6 AND I26 AND I14 AND VL4
VL8 =TON(VL7,500)
V_TRIPCB = VL8
VL9 =TON(VL8,1000)
VL10 =I11 AND I14 AND I26 AND VL9
VL11 =TON(VL10,500)
V3 =VL11

2#备供

VL1= NOT PVTS_1_3
V1 = VL1 AND P59_1_7 AND P59_1_8 AND P59_1_9
VL2 = I26 AND I14
VL3 =TON(VL2,500)
V_TRIPCB = VL3
VL4 =TON(VL9,1000)
VL5 =I11 AND I14 AND I26 AND I21 AND I24
VL6 =TON(VL5,500)
V2 =VL6
