This article relies on the actual example of 1 000 MW unit of a balancing generator equipped with a dual-machine regenerative system that has been successfully put into operation

and conducts research on the practical application of this system in 1 000 MW unit.Through the research on the wiring of the electrical system

combined with the practice in the power plant

its advantages and disadvantages are summarized

and professional suggestions on the equipment configuration and layout of the electrical system are put forward.After systematic analysis

a reasonable and targeted optimization scheme is given

aiming to fully improve the operation efficiency of the dual-machine regenerative system in 1 000 MW unit.
