| In the past,most of the current grid is in the form of a centralized grid,however this form of power grid already can’t easily track real-time changes in load within power system.Since the original single power supply system becomes a multi-power supply system,and combining distributed power supplies with large power grids becomes more and more complicated,which will change the distribution of the network and in the event of failure when the fault point of short-circuit current and voltage.The above situation will have a negative impact on relay protection and automatic devices.In the study of the impact of wind power generation on relay protection and automatic devices,the article is classified according to the location of wind power in the distribution network,and analyzes the different effects of different access positions on the short circuit current.According to these impacts,relay protection setting and setting value are readjusted to make the protection device more reliable and safer.In view of this,this paper presents a method of rapid switching based on wind power generation,and simulates the change of motor voltage and speed and wind turbine speed in four kinds of switching modes for fast,capturing and residual pressure,Can be seen from the results,the article proposed method to a certain extent,weaken the impact of the adverse effects,improve the success rate of switching. |
