Abstract

The invention discloses a double salient generator voltage adjustment control device and method having anti-interference capability. The method is characterized by, establishing a third-order linear state observer through detecting the output voltage of a generator and establishing switch tube control rata of a voltage regulator by utilizing output voltage reference values and linear state observer parameters, thereby realizing prediction correction of the output of the generator, improving dynamic response of the generator, reducing static difference, realizing auto-disturbance rejection function and overcoming the defects in the conventional control technology. The realization of the control method needs the combination of related hardware circuits. The required hardware circuits are simple in structure; the control method finishes related algorithms mainly by depending on a microprocessor; the overall used devices in the scheme are few; the production cost is low; and the device and method have extremely-high disturbance rejection performance and output voltage static difference.

Description

technical field [0001] The invention specifically relates to a double salient generator voltage regulation control device and 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 applie...
