Abstract


Excitation and governor system model as a grid analysis and calculation of the most important part of the four types of component model , the dynamic characteristics of the power grid analysis has a key role in the power sector in the past often typical parameters difficult to truly reflect the dynamic characteristics of the system , pressing the need for further modeling research work carried out on the two aspects of the structure and parameters of these models , this article is around the grid needs to expand the study to the overall recognition of the excitation and governor systems , mainly following . First, starting from the actual grid demand , were introduced to the development process and the research status of excitation and governor system model and parameter identification technology , discusses the necessity of using intelligent recognition method the whole parameter identification of excitation and governor systems , as well as formation of the urgency of the parameter identification of a higher degree of practical engineering application software , a clear objective of the study . Subsequently, to establish the purpose of the package which needs to build identification with the standard model library is described , from the demand point of view expounded the necessity to build the model library . Not detailed enough for the existing standard model to explain the typical standard model in accordance with the actual physical prototypes , dismantling , and a detailed explanation and description for each part , clear physical meaning of the model parameters , and these parameters are corresponding physical phenomena. Generator link deal with the problem as well as identification of simulation in which the identification of the parameters of the overall process efficiency which derive a simplified model of generator excitation and governor system overall identification and Matlab / Simulink model achieve ; segmented simulation speed up the recognition speed , and improve the recognition efficiency . Finally, we proceed from the practical engineering point of view , the development of the overall excitation and speed control system based on intelligent identification method parameter identification visualization software , two of the main functions of the package is described from the parameter identification and parameter checking , the two parts of functional modules of the actual system parameter identification and verification and validated parameter identification and verification of the accuracy of the results , and by the time domain index .
