Analysis Of Reactive Power And Voltage Coordination Control For DFIG Wind Farm Cluster Connection

With the increasing scale of wind power generation and the increase of large-scale wind power Grid-connected capacity,reactive power compensation and voltage stability problems caused by large-scale wind power Grid-connected are becoming more and more prominent.Reactive power and voltage control after large-scale wind power Grid-connected is a problem to be solved at present.Most wind farms in China usually adopt centralized grid-connected mode.Wind farm clusters consisting of several wind farms with different capacities are close to each other in space and have close electrical connections.These wind farms can be integrated into a centralized substation for overall coordinated control.Through the establishment of coordinated control mode and unified control coordination,the voltage stability and loss reduction in wind farm cluster area will be significantly improved,thus further enhancing the power grid's ability to accept wind power.First,at the end of the fishing year,as an example of the modelling and simulation of wind energy production systems;solid capacitors with SVG and a combination of compensation strategies for compensation and research;SVG and solid capacitors under the Joint Reaction Action and under the SVG Compensation Effect most reactive effect to compensate for the effect of simulation voltage.Secondly,the control of the wind power in a state of tension using a dual strategy,a control area of the first and second tension level,a mathematical model for a wind energy for the control of the reaction force in wind farms,revive target power control research and electromagnetique.bonjour.groupe gts of fixed capacitors and methods of compensation on the basis of the region,it is a wind turbine on the basis of the center voltage regulation and voltage regulation,the centre has developed a strategy for optical control of the coordinati layer the reaction field of the duplex..Finally,according to a study of the voltage compensation strategy,double fault of capacitor voltage failure and svg and fixed order on the basis of the strategy,the network connection of]arge wind turbines can't use characteristics,and to analyze the characteristics of the failure of eoliennes.systeme flow power network voltage and the control voltage of two strategic analysis of wind wind power and network analysis on the area of concentration of defects,the validity of the strategy of the strategy of tension compensation and voltage control of the double checking nearly.
