Abstract

The invention discloses a DC system real-time detection method for a transformer station. The DC system real-time detection method comprises the steps of: enabling a storage battery to operate in a floating charge mode; enabling a control and detection unit to reduce charging voltage and starting a self-detection interruption system; enabling the control and detection unit to detect the storage battery and controlling the on-off state of a storage battery discharge circuit; increasing the charging voltage of the storage battery in order that the storage battery enters an equalizing charge mode. The method strengthens the real-time self-detection of the storage battery and intensifies the connection to a DC system. The self-detection mode of the storage battery can automatically detect the advantages and disadvantages of the storage battery in real time in a normal floating charging operation mode and verify the integrity of the DC circuit through the readings of an ammeter. Compared with a conventional storage battery checking charge and discharge test, the method is safe and reliable, saves time and labor, and prolongs the service life of the storage battery.

Description

technical field [0001] The invention relates to the technical field of substation safety control, and more specifically relates to a real-time detection method for a DC system of a substation. Background technique [0002] The DC system not only provides reliable DC power for substation relay protection, automatic devices, control, signal and emergency lighting, but also provides reliable operating power for daily switching operations. Whether it is reliable or not directly plays a vital role in the safe operation of the substation. [0003] When the entire substation loses voltage and the charger stops working, the battery pack is the last barrier for the safe operation of the substation. Whether it can provide reliable DC power for the substation is of great significance. Accidents such as power outages and equipment burnouts in substations. Therefore, real-time and reliable online monitoring of batteries is of great significance to the entire substation and even the pow...
