The invention provides a system and a method for monitoring the internal resistance of a direct-current power supply valve-regulated lead-acid storage battery pack, and the system comprises the steps: introducing a switch control pair, carrying out the instantaneous direct-current discharge through the opening and closing of an MOS (Metal Oxide Semiconductor) tube, respectively collecting the voltages when the MOS tube is switched on and switched off, and calculating the internal resistance through the ratio of the voltage drop at the two ends of a storage battery to the discharge current. The internal resistance of each storage battery of the storage battery pack is monitored, which is of great significance for reducing the open circuit risk caused by further deterioration of the deteriorated storage battery, and a beneficial reference basis is provided for substation operation and maintenance personnel to prejudge the performance of the whole storage battery pack according to the monitored internal resistance value of the storage battery. Operation and maintenance personnel of the transformer substation can activate the storage battery pack or replace the degraded storage battery in a targeted manner according to the internal resistance monitoring value of each storage battery in the storage battery pack, so that a guarantee is provided for reliable power supply of the storage battery pack, and remarkable social and economic benefits are achieved.
Description
technical field [0001] The invention relates to the technical field of intelligent substation automation, in particular to a system and method for monitoring the internal resistance of a DC power supply valve-regulated lead-acid battery pack. Background technique [0002] When the three-phase AC power supply is normal, the DC bus voltage of the DC power supply system is provided by the normal charger, and the DC bus provides reliable and safe power supply for relay protection, automatic devices, circuit breakers and other units in substations at all levels. backup power. When the three-phase AC power fails or the charger fails to supply power normally, the DC bus voltage is provided by the battery pack to ensure the normal operation of relay protection, automatic devices and circuit breakers. [0003] The open circuit of the battery mainly refers to the state of high resistance and open circuit of some batteries in the battery pack. Generally, the battery is dehydrated and ...
