Abstract

The invention discloses a double salient generator voltage regulation control device and method with anti-disturbance capability. By detecting the output voltage of the generator, constructing a third-order linear state observer, and using the output voltage reference value and the parameters of the linear state observer to establish the control rate of the switching tube of the voltage regulator, the prediction and correction of the generator output is realized, and the generator is improved. The dynamic response reduces the static error, realizes the self-disturbance rejection function, and overcomes the shortcomings of the traditional control technology. The realization of the control method of the present invention needs to be combined with relevant hardware circuits. The required hardware circuit structure is simple, and the control method mainly relies on the microprocessor to execute related algorithms. The overall scheme uses fewer devices, lower production costs, and has strong anti-disturbance performance. and output voltage static difference.

Description

technical field [0001] The invention specifically relates to a double salient generator voltage regulation control method with anti-disturbance capability. technical background [0002] The doubly salient motor is a new type of reluctance motor developed in the 1990s. It has the advantages of simple structure, reliability and high-speed operation. According to different excitation methods, doubly salient pole motors are divided into doubly salient pole permanent magnet motors (DSPM), doubly salient pole electric excitation motors (DSEM) and doubly salient pole hybrid excitation motors (DSHEM). DSEM and DSHEM are suitable for generator operation due to the existence of electric excitation windings, the excitation adjustment is very convenient, and it is convenient to de-excite when a fault occurs. Although the excitation regulator (i.e. generator voltage regulator) for electric excitation and hybrid excitation doubly salient generators has been proposed and applied very earl...
