According to the situation where distributed high-power wind turbine generators are connected to the low-capacity distribution network of Liaohe Oilfield

it focuses on the impact of wind turbine cut-in/cut-out

sudden load change and short circuits on the transient stability of the power system.Utilizing Paladin Design Base simulation software

it analysizes based on the grid topology structure of one 6.25 MW doubly-fed wind turbine connected to the low-voltage side of the self-owned substation through the collection line

and completes the transient analysis of the power system in combination with the main electrical wiring diagram of the wind farm.Based on the actual production

it proposes relay protection strategies with the objectives of enhancing grid robustness and improving the stability of the distribution network after the integration of a high-proportion wind turbine system.It provides references for the research and practice of integrating new energy power generation into other low-capacity distribution networks.
