The invention relates to the technical field of
energy source devices, and discloses a
hybrid energy source energy buffer balanced micro-grid for a drilling
machine. The
hybrid energy source energy buffer balanced micro-grid comprises an energy conversion unit, a power supply access, distribution and conversion
bus coupler unit, main transformation units, a super
capacitor energy storage unit, a load loop
electricity conversion and
bus coupler unit and a master
control unit. The
hybrid energy source energy buffer balanced micro-grid is reasonable and compact in structure, and convenient to use; by a plurality of paths of power supply or various power supply, site resources are utilized to the maximum possible extent; and energy complement and comprehensive utilization are realized. The super
capacitor energy storage unit is provided with charging current by rectifiers of a plurality of main transformation units, so that
capacity sharing is realized. By the plurality of main transformation units, segmental power supply is realized by combining with the
electricity load characteristics. By a complementary work generation device or an
internal combustion engine preheating generation device, the
system power is dynamically adjusted and balanced; the oscillation frequency of the
system and the peak and valley difference value of the load power curve are reduced; and the
hybrid energy source energy buffer balanced micro-grid has the characteristics of being safe, labor-saving, simple, convenient and efficient.
