The invention provides an energy storage module testing device relating to the field of electric power and electric network. A first energy storage module, a first charging and discharging module, a second isolating transformer, a second charging and discharging module and a second energy storage module are sequentially electrically connected, a first isolating transformer, the second isolating transformer and the first charging and discharging module are sequentially electrically connected or the first isolating transformer, the second isolating transformer and the second charging and discharging module are sequentially electrically connected, the first energy storage module, the first charging and discharging module, the second energy storage module and the second charging and discharging module can be taken as a load and a power supply mutually, so that a charging and discharging test is carried out mutually; and electric energy is fed back to an electric network by virtue of the first isolating transformer or the electric energy is acquired from the electric network, so as to adjust electric quantity of the first energy storage module or the second energy storage module to meettesting standards, thus a risk that the first energy storage module or the second energy storage module is damaged when being accessed to the electric network is reduced, debugging time after grid connection is shortened and impact of the energy storage modules on the electric network in a testing process is also reduced.
Description
technical field [0001] The invention relates to the field of power grids, in particular to an energy storage module testing device. Background technique [0002] The whole composed of substations of various voltages and transmission and distribution lines in the power system is called the power network. It includes three units of power transformation, power transmission, and power distribution. The task of the power grid is to transmit and distribute electric energy and change the voltage. When a large amount of power is injected into the grid or absorbed from the grid, it will cause fluctuations in the grid. The existing megawatt-level energy storage system serving the grid has huge power, and there is no condition to conduct a comprehensive test before connecting to the grid. Because it cannot be fully tested before connecting to the grid, the risk of connecting the energy storage system to the grid is increased, and the debugging time after grid connection is also increa...
