Abstract: A method of reducing cold startup time of a genset which includes an engine and a generator for providing a requested power to a utility grid or load comprises determining if the generator is electrically coupled to a utility grid or load. In response to determining the generator is electrically coupled to the utility grid or load, a speed bias value is controlled in response to the power being produced by the genset. The speed bias signal represents a difference between a target power output and a current power output of the genset. The power of the engine is controlled using the speed bias value.

Abstract: A method of reducing cold startup time of a genset includes providing a lubricant to the genset at predetermined time intervals before a genset startup. The lubricant is heated to a predetermined lubricant temperature using an external heating system. A high temperature coolant of the genset is heated to greater than a predetermined high temperature coolant temperature. The speed of the engine is ramped to a target speed continuously without pausing at a speed lower than the target speed. Genset electrical parameters of the genset are synchronized to utility grid or load electrical parameters of the utility grid or load. The genset is electrically coupled to the utility grid or load such that the synchronizing and electrically coupling are performed within a predetermined synchronization time. A fueling rate and a spark timing is adjusted based on a power being produced by the genset.

Abstract: Systems and apparatuses include a control unit structured to communicate with a first generator set, a second generator set, and a third generator set, operate the first generator set as an output generator in an exercise mode, and operate the second generator set and the third generator set as load generators in the exercise mode to use electrical power produced by the first generator set. The second generator set uses a second genset portion of the electrical power and the third generator set uses a third genset portion of the electrical power.
