[0024] Example 1
[0025] figure 1 It is shown that an electrified railway non-phase through power supply system is composed of: the traction transformer in the traction substation S is a three-phase-two-phase balance transformer T, and the three-phase-two-phase balance of each traction substation S The primary three phases A, B, and C of the transformer T are all connected to the three phases A′, B′, and C′ of the same utility grid P, and the power flow controller PFC is connected to the two output phases of the three-phase-two-phase balance transformer T Between α and β, one of the two output phases α and β supplies power to the locomotive; and each traction substation S uses the same phase ( figure 1 The middle is α-phase) to supply power to the locomotive.
[0026] Figure 4 It shows that the power flow controller PFC of this example is composed of a single-phase isolation transformer one T1, a voltage source inverter one NB1, a DC coupling capacitor C1, a voltage source inver...
