Hybrid power system with variable speed genset

摘要

A hybrid power system is disclosed. The hybrid power system may include a primary power source configured to provide a primary power, and an energy storage device coupled to the primary power source, the energy storage device configured to store excess primary power provided by the primary power source. The hybrid power system may further include a variable speed genset, the variable speed genset including a secondary power source configured to operate at a variable rotor speed to provide a secondary power responsive to power requirements of a load. The hybrid power system may also include a central controller communicatively coupled to the primary power source, the energy storage device, and the variable speed genset, the central controller configured to control the primary power source, the energy storage device, and the variable speed genset based on the power requirements of the load.

1. A hybrid power system, comprising:
a primary power source configured to provide a primary power; an energy storage device coupled to the primary power source, the energy storage device configured to store excess primary power provided by the primary power source; a variable speed genset, the variable speed genset including a secondary power source configured to operate at a variable rotor speed to provide a secondary power responsive to power requirements of a load; and a central controller communicatively coupled to the primary power source, the energy storage device, and the variable speed genset, the central controller configured to:
control the primary power source, the energy storage device, and the variable speed genset based on the power requirements of the load,monitor the power requirements of the load and a power output of the variable speed genset,use a subtractor node to determine a difference between the power requirements of the load and the power output of the variable speed genset, andadjust a rotor speed of the variable speed genset so that a magnitude of an adjustment to the rotor speed depends on a magnitude of the difference; and wherein the hybrid power system is configured to supply at least one of the primary power and the secondary power to a telecommunication system.
