| Synchronous generator is an important part of power system, its stable operation is directly related to the stability of the entire power system. The various disturbances in power systems will affect stable the operation of synchronous generators. So, the research on various disturbances affects synchronous generators operation and exciter optimal control methods, which is of the urgent problems need to resolve in the actual industrial production.Based on the characteristics of various disturbances, the paper uses a exciter control method of large step disturbance objectives guide and control toward goals, and designs based on the TMS320LF2407 exciter control devices, which can achieve the laboratory step disturbance control experiments.At first,the paper introduces the various disturbances in the power system, analyzes international exciter control research methods, presents purpose and meaning of this paper. Then, introduces about DSP ,which is the basis knowledge of next design Based on DSP exciter control devices . In addition, on the basis of deterministic analytical methods, for the quadric form optimal methods not intended step disturbance voltage stability control process, according to the specific request in the different types of operational disturbances transiting to the new operation point ,this paper takes the target main affecting control results as priority,presents a phased control methods that single target guiding and accurate control of approach targets. To test the effectiveness of this control method, the paper developes the exciter control devices that based on DSP. Finally, on the basis of... |
