Adaptive control technology of phase current between modules of photovoltaic power generation system
This paper is now proposed photovoltaic power generation system module phase current adaptive control technology.In the case of taking into account the capacity limit of the transformer,the negative sequence current of its margin output is fully utilized to provide zero sequence current for the single-phase traction load while ensuring the full output of the photovoltaic power generation,reducing the asymmetry between the grid access points,so as to realize the adaptive control of the phase current between the photovoltaic power generation system modules without phase sequence isolation.Experimental results:The phase current adaptive control technology between PV power generation system modules can effectively control the balance of the three-phase current in the transmission network,and the current of each phase in the PV power generation system can achieve relative balance through this technology,so as to improve the efficiency and stability of the system.
