摘　　要：面向低压电网的小型户用光储一体系统,存在构网型与跟网型两种控制结构,常规的光储逆变器和控制器无法实现两者的兼容。为了解决不同应用场景下对两种控制结构的需求,提出光储一体系统的硬件设计方式,实现单相光储一体系统的构网控制与跟网控制的灵活切换。硬件设计综合考虑计量、控制、保护、通讯及显示功能要求,并在实际运行环境中进行构网运行和跟网运行下的性能测试。The small household photovoltaic storage integrated system for the low-voltage power grid includes grid-constr ucting control str ucture and grid-following control structure.However,it is hard for the conventional photovoltaic storage inverter and controller to realize compatibility.In order to meet the requirements of the two kinds of control structures in different practical application scenarios,the hardware design method of the photovoltaic storage integrated system is proposed to realize the flexible switching between network building control and network following control in the single-phase photovoltaic storage integrated system.This hardware design comprehensively considers the functional requirements of metering,control,protection,communication and display.The performance test is always conducted both under the network construction operation and network following operation in the actual operation environment.
