Generalized Equivalent Model Construction Method for Wind Farm with Direct-drive Turbines Based on Single-machine Model Extension
摘要
Abstract
Constructing the dynamic equivalent model of wind farms is the basis for analyzing the grid-connected wind power system.Currently,the commonly used multi-machine equivalent modeling methods for wind farms need to reconstruct the equivalent model according to the clustering indicators for different operation scenarios.When used for online dynamic security analysis,the equivalent model needs to be continuously reconstructed,which affects the efficiency.Therefore,it is necessary to establish a generalized equivalent model for wind farms applicable to any operation scenario.Based on this,a generalized equivalent model construction method for wind farms with direct-drive turbines is presented.First,the neural network structure and input parameters are designed,and a generalized neural network model for the single permanent magnet synchronous generator(PMSG)is constructed.Then,through the equivalent calculation of input parameters,the single-machine generalized model is extended to wind farms,and a generalized equivalent model construction method for wind farms is developed.Finally,a simulation integration method for a generalized equivalent model is studied based on the CloudPSS electromagnetic transient simulation platform,and the effectiveness of the proposed model is verified through simulation.关键词
