Abstract

The invention provides an excitation adjustment system and method for a nuclear power station generator. The adjustment system comprises an input / output module with two input / output plates, an excitation logic control module with three control signals including onsite input, excitation switch switching-on and excitation input, and a grid connection logic control module with signals indicating the state of a breaker at a generator outlet. A part of input signals in the input / output module are redundant arranged on the two input / output plates, and the logical operation relation of the excitation logic control module and the grid connection logic control module in the excitation adjustment system is changed. The excitation adjustment system and method overcome design defects of an excitation adjustment system in the prior art in multiple aspects, adjustment means is improved, the good operation state is guaranteed, and accordingly long-term safe and stable operation of a nuclear power station generator set is guaranteed.

Description

technical field [0001] The invention relates to an excitation system, in particular to an excitation adjustment system and method applied to a nuclear power plant generator. Background technique [0002] As the key equipment of generators in million-kilowatt nuclear power plants, the main function of the excitation regulation system is to establish the space magnetic field necessary for power generation for the excitation current of the generator. Therefore, the state of the excitation regulation system is directly related to whether the generator set can operate normally. Once the excitation adjustment system fails, it may cause damage or even burning of the entire exciter and generator, resulting in shutdowns and other events, which will affect the safe and reliable operation of the generator set. Therefore, the excitation adjustment system requires long-term safe and stable operation. Reliable design and easy maintenance. [0003] In the prior art, there are many design ...
