Abstract

Provided are an off-grid start method and system for a new energy power generation system. The method includes: gradually boosting the voltage of a master according to a plurality of preset voltage given values, and slaves determining, by means of measuring a voltage of the load of a system, a target voltage given value used by the master; and the master determining, by means of monitoring an output current of the master itself, that a slave is successfully connected in parallel, and then continuing to boost the output voltage until all the slaves run in parallel. Therefore, according to the solution, no upper-layer synchronous control is required during a black-start process, and no communication between a master and slaves is required.
