Problems solved by technology

In the DC system, the battery is the last safety barrier of the entire DC power system. Once a problem occurs, the protection will fail, the switch will refuse to operate, and the channel will be interrupted. The consequences will be unimaginable.
[0003] Current electric DC system batteries generally adopt the following method for online discharge test: close the DC output of the charger, and use the battery to supply the DC load of the entire power plant or substation, so as to realize the discharge capacity test of the battery, but because the DC load is generally relatively large Small and uncertain in size, it cannot meet the constant current discharge requirements of the battery; the constant current discharge load is connected in parallel with the DC load to discharge the battery, which solves the problem that the current of the DC conventional load is too small, but due to the large size of the DC load OK, still unable to meet the constant current discharge requirements of the battery

Description

technical field [0001] The invention relates to the technical field of power storage battery testing, in particular to a DC testing system and testing method for power storage batteries. Background technique [0002] The DC power system is one of the core equipment of the power grid. It provides reliable DC power for control, signal, relay protection, automatic devices and emergency lighting in the substation, and also provides reliable operating power for operations. The reliability of the DC system plays a vital role in the safe operation of the substation and is the guarantee for the safe operation of the substation. In the DC system, the battery is the last safety barrier of the entire DC power system. Once a problem occurs, the protection will fail, the switch will refuse to operate, and the channel will be interrupted. The consequences will be disastrous. [0003] Current electric DC system batteries generally adopt the following method for online discharge test: clos...
