Abstract

The invention relates to an excitation regulator which is connected to an excitation power module and a generator. The excitation regulator comprises a first control system, a threshold setting systemand a second control system. The first control system is connected to the generator and is used for receiving a feedback signal outputted by the generator and outputting a logic signal for magnetization or demagnetization. The threshold setting system is connected to the first control system and is used for receiving the logic signal for magnetization or demagnetization and outputting a manual orautomatic mode threshold signal. The second control system is connected to the excitation power module and is used for outputting a trigger pulse signal according to the feedback signal and the manual or automatic mode threshold signal, and the trigger pulse signal is used for adjusting an excitation current signal outputted by the excitation power module. The problem that a traditional thresholdsetting system relies on the mutual cooperation of mechanical components to realize the magnetization or demagnetization operation of the generator and a set value cannot be automatically adjusted issolved.

Description

technical field [0001] The invention relates to the field of excitation control of nuclear power plant generating sets, in particular to an excitation regulator and an excitation system. Background technique [0002] The excitation system is the key control equipment of the diesel generator of the nuclear power plant emergency diesel generator set. By providing the excitation current to the generator rotor, the output voltage and reactive power of the generator are controlled to ensure the stable operation of the unit. The excitation system is mainly composed of an excitation power unit and an excitation regulator. The excitation regulator receives the feedback signal provided by the generator, and after processing, outputs a trigger pulse signal to control the SCR of the excitation power unit to provide excitation current for the excitation winding of the generator. [0003] The threshold setting device is a key component of the excitation regulator, which is responsible f...
