Study on a small‐signal analysis method for PMSG considering LVRT control and frequency regulation

نویسندگان

چکیده

In a high proportion of new energy grids or 100% source power grid, the dynamic performance PMSG under fault conditions is very important. However, current small signal model lacks detailed and deep analysis permanent-magnet synchronous generator (PMSG)-based wind generation LVRT control. Here, pre-fault, after failure recovery stages are established. This paper employs linear analyses to characterize PMSG-based system control practical characteristics. particular, conflict between frequency regulation discussed based on constructed model. On this basis, impact dc-link bandwidth during stage discussed, active damping method analysed improve stages. Finally, time-domain simulations utilized verify models discussed. The research results in helpful promote conditions.

Equivalent modeling of PMSG-based wind power plants considering LVRT capabilities: electromechanical transients in power systems

Hardware protection and control action are two kinds of low voltage ride-through technical proposals widely used in a permanent magnet synchronous generator (PMSG). This paper proposes an innovative clustering concept for the equivalent modeling of a PMSG-based wind power plant (WPP), in which the impacts of both the chopper protection and the coordinated control of active and reactive powers a...

A New Control Method for Smoothing PMSG-based Offshore Wind Farm Output Power

Nowadays, propagation of wind turbines make challenges to supply safe power to the grid. Because of wind speed changes, supervisors are concerned to wind turbines, be able to produce appropriate electric power during the wind speed changes. As a matter of fact, investors are mostly like to invest on offshore wind farms, because of their more stable and continuous wind speed rather than onshore ...
