Simultaneous merging route diagram

Since the vehicle is paralleled at the same time, the generator does not add excitation, and there is no voltage on the generator bus, only residual voltage (about a dozen volts), so
the operation is relatively simple.
    As long as the speed (frequency) of the standby generator rises to a value close to the speed (or
frequency (the difference can be ±2.5%, not necessarily exactly equal), the standby generator will be closed. The main switch of the motor is quickly turned on to the excitation
, so that the standby generator can quickly be synchronized by the system.
    The self-synchronous parallel connection is shown in Figure 7-9; the secondary wiring is shown in Figure 7-9.
