The invention relates to the technical field of
simulation systems of
new energy grid-connected power generation, in particular to a photovoltaic grid-connected power generation semi-real object
simulation system; the photovoltaic grid-connected power generation semi-physical
simulation system comprises a simulation
program integration execution platform, a simulation
machine, a real object part,a
signal acquisition
system of the real object part and a simulation photovoltaic power supply, wherein the simulation
program integration execution platform is used for executing a program and transmitting a
signal to the simulation
machine and the
signal is converted into an electrical signal for running the real object part through the simulation
machine; the simulation photovoltaic power supply is used for providing a grid-connected required
energy source for the real object part; and the
signal acquisition system is used for collecting the electrical signals of the real object part and feeding the electrical signals to the simulation
program integration execution platform. According to the system, the cost of a
new energy power generation photovoltaic array and an
electricity storagesystem thereof can be reduced, and the performance of a
new energy grid-connected system can be integrally mastered. According to the system, the problem of
instability caused by inaccurate tracking of the maximum power point of the new energy power generation is fundamentally solved, and the phenomenon of energy waste caused by oversaturation of the photovoltaic array under the actual working state is avoided.
