Soft Loading Base Load
The SLBL is a close transition soft loading device that parallels a single generator to a single utility power grid.
The controls in the SLBL perform active synchronization of the generator output with the utility power and vice versa during a power transfer process. The SLBL is suitable for a single generator with a single utility application where a close transition transfer with an extended parallel of the two sources is allowed by the utility power company.
The SLBL will operate at a base load (typically 80% of standby rating) so that the generated power will either be utilized by the facility loads or exported to the utility based on the total facility kW loads and the generating capacity.
The SLBL is a good choice for customers who require reliable emergency backup capability and bumpless transfer back to the utility when utility power returns. In addition the SLBL can also be used by customers for peakshaving applications without interrupting power to their critical loads during the peakshaving process. The transfer of power between sources is seamless.
