Abstract


The excitation regulation system is an important part of the hydroelectric unit , its main task is to provide an adjustable DC current to the field winding of the synchronous generator , control the generator terminal voltage is constant , and need to meet normal power generator , while controlling the generator set between the rational allocation of reactive power to improve the stability of the synchronous generator running in parallel , to meet the needs of the safe operation of the power system . With the generator unit capacity and grid scale increases , generators, and power system excitation control rising demands in terms of rapidity , reliability , versatility , the corresponding excitation control theory and practice are constantly updated , developed and refined. Traditional analog excitation regulator can not meet the need . In recent years , become the mainstream of the synchronous generator excitation regulator Excitation system based on microcomputer control system has been gradually replacing analog excitation regulator . Based on MSP430 microcontroller as the core , integrated analog and digital circuit for a hardware - based , reasonable algorithm by means of physical production , commissioning, to discuss the development of a new kind of generator excitation regulator . This paper is divided into four main parts . The first part is a single-chip microcomputer the excitation system structure , and discusses the basic system structure and the role of the various parts of each other work together . The second part of the MSP microcontroller - based hardware design of microcomputer-based excitation regulator . The third part of the control algorithm research , to discuss the application of PID control excitation device . The fourth part is the implementation and testing of the system , combined with a the actual debugging data to illustrate the usefulness of Excitation regulator .
