Grid Type Optical Storage Power Supply and Control Strategy in Water Transmission Engineering
The use of a grid type optical storage system to supply power to important loads in water transportation pro-jects is cost-effective and reliable.In order to address issues related to power supply continuity,voltage support,and surge current that may occur during the process of off grid and grid connected mode conversion in the photovoltaic storage sys-tem of water transmission engineering,this paper proposes a fast switching control strategy for electronic converters.The SCR forced shutdown method during the process from grid connected power supply to off grid power supply is theoretically analyzed,and the grid connected current shutdown time is calculated within different load voltage amplitude ranges.In ad-dition,the feasibility of the connection-separation seamless switching strategy for the networked optical storage system is verified through experimental results.
