The invention discloses a port shore-based alternating-current and direct-current hybrid power supply and a power supply control method. The power supply comprises at least one single-module converter. The single-module converter comprises a rectification module, an AC charging interface device, a DC charging interface device, a photovoltaic power generation system, an energy storage system and a controller. According to the invention, single-module operation independent control, multi-module parallel operation master-slave control and multi-energy coordination control can be realized. According to different ship types, multiple control modes such as ship direct-current power supply, ship alternating-current variable-frequency power supply and converter parallel compatibilization are realized. According to the diversified control method compatible with power supply of different ships, the problem that shore power cannot be used when the ships berth due to a single power supply mode is solved.
本发明公开了一种港口岸基交直流混合供电电源及供电控制方法,该供电电源包括至少一个单模块变流器;单模块变流器包括整流模块、交流充电接口装置、直流充电接口装置、光伏发电系统、储能系统和控制器;本发明可实现单模块运行独立控制、多模块并联运行主从控制以及多能源的协调控制。按照船舶类型的不同,实现船舶直流供电、船舶交流变频供电、变流器并联增容等多种控制方式。本发明兼容不同船舶供电的多元化控制方法,解决供电模式单一带来的船舶停靠无法使用岸电的问题。
