doi:10.12096/j.2096-4528.pgt.19160

Abstract

Abstract:

Aiming at the problem of low voltage ride through (LVRT) of the generation side uncontrollable rectifying permanent magnet wind turbine in the low voltage microgrid, the operating characteristics of the permanent magnet synchronous generator (PMSG) wind turbine during the grid voltage drop were researched. Based on the analysis of the DC link voltage instability mechanism, a LVRT control strategy was proposed combined operation method of the maximum current output of the grid side converter and chopper circuit. After judging the operating status of the wind turbine, the chopper circuit and the grid-side converter were coordinated controlled. In the case of full load, the DC link voltage was controlled by the chopper circuit, and the grid-side converter outputs the maximum current. In the case of light load, the DC link voltage was controlled by a conventional voltage loop, and the residual current capacity of the grid-side converter was used to transmit reactive power. The simulation results of the system show that LVRT can be achieved effectively by the generation side uncontrollable rectifying permanent magnet wind turbine under two working conditions.

Key words: low voltage microgrid, wind turbine, low voltage ride through (LVRT), chopper circuit, maximum current output
