parallel operation

More than 2 generators supply power to the grid at the same time

Parallel operation, generally important power stations (especially Ship power station ）There are more than 2 Synchronous generator set As the main power supply. Two or more generators supply power to the grid at the same time Generator Set The process of parallel operation of the unit. It is also called input parallel, or parallel, whole step.

Chinese name: parallel operation

Alias: Put into parallel connection

Parallel operation for power generation has the following advantages:

1. Considering that the generator operates with the highest efficiency under the rated load. With two or more generators, the operation mode can be changed according to the load, so that the generator is always in the best operation state.

2. Keep the continuity and reliability of power supply.

Ideal paralleling conditions: the effective value of voltage is the same, the phase of voltage is the same, the frequency of voltage is the same, and the phase sequence of voltage is the same.
