Abstract

In order to provide a method for regulating a reactive power compensator, which is connected to an alternating current line having multiple phases, wherein for each phase an actual voltage V12, V23 and V31 present thereon is detected and from the actual voltages V12, V23 and V31 a counter system actual fraction is calculated. A control circuit suppresses the counter system actual fraction. A feedback loop determines the level of suppression of the counter system actual fraction with the help of controlled parameters. The method enables an adjustment of the counter system that is largely independent from operating staff. Accordingly, a comparator unit compares the counter system actual fraction to the counter system target fraction and defines the controlled parameters as a function of the comparison.
