The genset is running, when a unit with overloading, after closing for the other units of power sharing, because of the need to transfer more load, if do share transfer directly can cause the shock of the two units and big speed fluctuation, so the load transfer process needs soft loading process. Due to the response of unit and the controller is inconsistent, it can lead to the soft loading process after the completion of the units is still volatile, so the controller uses the ladder soft loading, it can increase delay point when soft loading and to get early ease for over regulation or under regulation.
The specific process is as follows:
When the circuit breaker of genset closing, the genset power gradually rise, the power to set the power delay points or delay point integer times, delay after a period of time, continue to increase power until soft loading process is complete.
For example: delay loading point is set to 10%, loading time delay is set to 10 seconds, pause loading after genset power gradually rising to 10%, after the expiration of 10 seconds delay, continue to load, pause loading after power up to 20%, after the expiration of 10 seconds delay, continue to load, pause loading after power up to 30%, after the expiration of 10 seconds delay, continue to load until soft loading process is complete, begin to the normal load sharing after reaching share power.
