Open source ship shore power hybrid microgrid scientific research test platform

Abstract

The invention relates to an open source ship shore power hybrid microgrid scientific research test platform comprising a real-time simulation controller and a fan simulator, and the real-time simulation controller is connected with a PC, a shore power simulator, a photovoltaic simulator and a battery simulator. The photovoltaic simulator and the battery simulator are connected to a direct current bus through a DC-DC converter, the direct current bus is further connected with a first DC-AC converter in a hanging mode, and the alternating current bus is connected with the shore power simulator through a grid-connected switch; the fan simulator is connected with a second filter through two second DC-AC converters which are connected back to back, signals of the fan simulator are sent out by the real-time simulation controller through a signal adapter plate, and grid-connected switch signals are accessed to the real-time simulation controller through the signal adapter plate. According to the method, the defects in the prior art are overcome, and the real-time simulation controller and the digital signal switching system based on the SIMULINK graphical programming mode are introduced to carry out defect processing so as to solve the problems that an open-source comprehensive platform is low in development efficiency and has potential safety hazards.

Description

technical field [0001] The invention relates to the technical field of open-source scientific research and testing of micro-grids, in particular to an open-source ship shore power hybrid micro-grid scientific research and testing platform. Background technique [0002] With the depletion of fossil energy and the increasing attention of governments to environmental pollution, electricity and new energy are gradually introduced into the ship energy system. The state encourages ships to use shore power after berthing, and has issued regulations and policies to support it; at the same time, the efficient and reasonable use of new energy in ship power supply systems through energy storage equipment and power electronic devices has gradually attracted research at home and abroad. attention. However, most of the traditional experimental platforms do not have the conditions for shore power research and mixed load power supply for independent ships, and most of the more complex plat...
