Jidong Oilfield Machinery Company Microgrid Technology Won the National Invention Patent

On May 14, "A multi-source DC power supply topological circuit" declared by Jidong Oilfield Machinery Company was authorized by the State Intellectual Property Office for invention patent.

The invention patent relates to the field of microgrid technology, which can effectively solve the intermittently and unstable problems existing in the distributed power supply itself, and provides a flexible and efficient solution for distributed power generation in the range of low and medium voltage. By combining the distributed power supply, load, energy storage device and control system and connecting the controllable interface with the large power grid, it can ensure that when the input DC of the multi-source DC is insufficient, it can switch to the energy storage circuit for power supply, and when the energy storage circuit is insufficient, it can access the DC power supply through the external network. The whole process does not need to rely on external software control, rapid and sensitive response, strong stability.

This invention not only improves the operational efficiency and reliability of the microgrid, but also provides a strong technical support for the efficient use of distributed energy and the construction of smart grid. In the next step, the machinery company will continue to devote itself to technological innovation and contribute to the continuous promotion of green transformation.
