Modelling and Optimization of Wind Turbine Electromechanical Transient Characteristics Using Magnitude Phase Motion Equations
摘要
Abstract
The impacts of wind turbines on the power system (synchronous generator) transient stability increase with their increasing penetration level.It is thus of importance to understand the characteristics of these devices and optimize them to achieve a higher transient stability level.Most understandings nowadays are deduced from simulation results based on simulation models,with little from mechanism analyses based on physical models.The paper first established the magnitude phase motion model of GE wind turbine in electromechanical timescale,then analyzed and optimized the wind turbine characteristics.The study reveals that the wind turbine in terms of electromechanical characteristics during grid-fault only responds to the system voltage magnitude dynamics,and does not respond to angle dynamics.The occasional incapability of voltage magnitude in reflecting the dynamics of synchronous generators during grid-fault restricts the support that wind turbine can provide to the transient stability improvement of synchronous generators.The paper overcomes the restriction by introducing system frequency dynamics into the wind turbine current limiting control.Simulations on two area four machine system show an improved synchronous generator transient stability with the optimization.关键词
