The invention relates to the technical field of
new energy storage, and discloses a liquid leakage detection and collection method for a galvanic
pile of a
flow battery energy storage system, which comprises the following steps of: arranging a
humidity sensor, a gas sensor, a temperature sensor, a visual sensor and a
pressure sensor in a key area of the galvanic
pile to form a high-density detection network of multi-
source data; sensor data are collected and transmitted to a control center in real time, multi-
source data are fused through Kalman filtering, Bayesian
estimation and a
deep learning model, and feature information of liquid leakage is obtained; and based on feature information of multi-
source data fusion, a multi-point interpolation method and three-dimensional space modeling are used to realize positioning of a liquid leakage area. The intelligent grading response and control technical scheme is adopted, and factors such as leakage
diffusion and environmental conditions are dynamically analyzed, so that grading self-
adaptive response of operations such as isolation, cooling,
load shedding and shutdown is realized, and compared with the scheme that only single isolation or shutdown is adopted to cope with a leakage event in the prior art.
