Abstract

The invention relates to an automatic device for an excitation regulating characteristic test. The automatic device comprises an operating table, a DCS (distributed control system) intermediate relay, a time relay, a power analyzer and an excitation cabinet. The time relay comprises an instant closed open contact, a delay closed open contact and a coil of the time relay, the operating table is connected with a coil of the DCS intermediate relay which is connected with the coil of the time relay, the instant closed open contact is connected with the power analyzer, and the delay closed open contact is connected with the excitation regulation cabinet. Compared with the prior art, the automatic device for the excitation regulating characteristic test has the advantages of complete recording, low energy consumption, economized time and the like.

Description

technical field [0001] The invention relates to an excitation adjustment device, in particular to an excitation adjustment characteristic test automation device. Background technique [0002] The automatic excitation adjustment device controls the output of the excitation power unit according to the change of the terminal voltage of the generator, so as to achieve the purpose of adjusting the excitation current. [0003] The automatic excitation regulation system of the synchronous generator plays an important role in the normal operation and accidental operation of the generator. An excellent excitation regulation system can not only ensure the safe operation of the generator, provide qualified electric energy, but also improve the stability of the power system. [0004] After the unit is put into operation or the unit is overhauled, an excitation characteristic test is required to test whether the characteristics of the automatic excitation adjustment system meet the opera...
