Methods and systems for operating engine generator sets
First Claim
1. An engine generator set comprising:
- an electrical generator configured to provide electrical energy to a first load rated at a first voltage and a first frequency, and to provide electrical energy to a second load rated at a second voltage and a second frequency wherein at least one of the second voltage is different than the first voltage and the second frequency is different than the first frequency;
a prime mover rotatably coupled to said generator through a shaft, said prime mover configured to rotate said shaft at a first rotational speed when said electrical generator is generating electrical energy at the first frequency and to rotate at a second rotational speed when said electrical generator is generating electrical energy at the second frequency;
an engine generator set control system comprising;
a generator control system communicatively coupled to said electrical generator configured to control an output of the electrical generator;
an engine control system communicatively coupled to said prime mover configured to control a rotational speed of said shaft; and
an output selector communicatively coupled to said generator control system and said engine control system, said output selector configured to modify the output of the engine generator set from the first voltage and the first frequency to at least one of the second voltage and the second frequency; and
an electric motor supplied with electrical power from the output of said electrical generator through a motor protection circuit that includes at least one of an overload and a trip unit communicatively coupled to said output selector such that a trip setting of the at least one of an overload and a trip unit is modified by operation of the output selector.
