Method of automatic setting of continuously and/or discretely tunable quenching choke in electric power system compensated network

摘要

The automatic setting method quenching reactor (9) using the auxiliary signal (14) supplied to the point of non-rotating component electrical system (10). The auxiliary signal (14) comprises a current or voltage having a variable angular frequency and is used for determining the resonant angular frequency .omega..sub.rez.n.aktuálního state of the electrical system (10) that is compared with a basic angular frequency .omega. .sub.sn (10). Quenching reactor (9) is then tuned towards the desired resonant condition L.sub.Srez.n .. The auxiliary signal (14) used for tuning arc suppression (9) may also comprise at least one pair of complementary frequency components with the same high amplitude, whose angular frequency .omega..sub.in, .omega..sub.ii.n.je chosen so that the response, the electrical system (10) to the auxiliary signal (14) for these two complementary angular frequency .omega..sub. in, .omega..sub.ii.n.byla equally large at that point just tuning in, where the circuitry for basic angular frequency .omega..sub.sndosahuje resonance condition. For debugging quenching reactor (9) is utilized (13) comprising a generator (8) of the auxiliary signal connected to the zero point of the system (10), an evaluation unit (11) and a control unit (12), the device (13) is provided with hardware resources and a software module (15) controlling the frequency of the auxiliary signal (14) and evaluating the response of the electrical system (10) for performing automatic setting method quenching reactor (9) according to the invention.
