Problems solved by technology

[0003] At present, the analysis of the reliability of the communication network is mainly measured by various reliability indicators, among which the research on the invulnerability index has received more and more attention, but there is no research on applying the invulnerability to the WAMS communication network structure. Literature or reports; the transient parameters of the generator are still an important factor affecting power oscillation and system stability. However, the accurate identification of the parameters of the synchronous generator, especially the transient reactanc

Abstract

The invention discloses a synchronous generator parameter identification and control method based on a WAMS. An improved saturated cutset algorithm is adopted in a communication network framework of the WAMS, a method based on time domain transformation is adopted in parameter identification of a synchronous generator, and excitation backstepping control based on a neural network is adopted in control over the synchronous generator. The improved saturated cutset algorithm of the communication network framework of the WAMS, synchronous generator parameter identification of the method based on time domain transformation and the synchronous generator excitation backstepping control method based on the neural network are combined together, and therefore the system has euryzonal performance, intellectuality and reliability.

Description

technical field [0001] The invention relates to a method for parameter identification and control of a synchronous generator based on WAMS, which performs parameter identification and excitation control for a synchronous generator in a wide-area electric power system, and belongs to the technical field of electric engineering. Background technique [0002] WAMS system (Wide Area Measurement System) is developed on the basis of synchrophasor measurement technology, and it is a system for dynamic monitoring and analysis of power systems with a wide area. The WAMS system provides a dynamic information platform for the smart grid, which will promote the development of smart grid operation planning and control technology. It can monitor the state quantity of the power system in real time, identify the disturbance of the power system, and predict the problems of the system in advance, and has an extremely wide range of applications. [0003] At present, the analysis of the reliab...
