Embodiment Construction
[0024] refer to figure 1 , the embodiment of the present invention provides a control method for reactive power compensation, including step S110, collecting grid data; step S120, processing the grid data to obtain a power factor; step S130, comparing the power factor with a set value, according to Comparing the results, perform the switching operation of switching first and switching first; step S140, judging whether the capacitor branch is good or bad, and correspondingly calling the backup branch operation according to the judgment result. By judging the quality of the capacitor branch and automatically calling the backup branch, not only the stability and reliability of the capacitor bank are improved, but also the service life of the compensation device is extended and the maintenance cycle of the reactive power compensation device is shortened.
[0025] In another embodiment, the set value includes input set value and cut-off set value. When the power factor is less than...
