Abstract

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.

Description

technical field [0001] The invention relates to the technical field of power supply devices, and relates to a mixed energy energy buffering and balancing microgrid for drilling rigs. Background technique [0002] With the rapid development of science and technology, many intelligent, networked and automated equipment are widely used. However, due to many reasons, many old equipment with high pollution, high energy consumption and low efficiency are still in use, especially the mechanical drilling equipment powered by diesel engines, which have been in service for a long time and run in harsh environments. High-power lifting traction equipment and large inertia rotating equipment often have large power fluctuations during operation. Each single equipment will cause impact on the mechanical transmission system and power system at the moment of starting and stopping. Therefore, it has to be equipped with a larger The high-power diesel engine is used to deal with the impact loa...
