Research On Clusters Control Technology Of Multiple Types Wind Farm

With the continuous progress of wind power technology. Single wind turbine's capacity is increasing, and The construction of wind farms are greatly accelerated the process. The grid power Increased by installed capacity of wind farms, Wind power generation system and grid are getting closer. This paper focuses on heterogeneous wind farms into power on the grid system and the impact of wind turbines. Study the heterogeneous grid wind farm active power and frequency of access to coordinated control strategy and the reactive power and voltage of the coordinated control strategy.Power quality is caused by wind power becomes more and more to highlight. It is particularly important to Research power quality problems caused by wind power.This paper analyzes the wind power generation system theory, mathematical model and control strategy of permanent magnet synchronous generator.Squirrel-cage Induction generator and double fed induction generator Wind Power Generation System. And Wind farms and network simulationed by Software of PSCAD. Compared the three different types of variable speed constant frequency wind power generation system with characteristics, which provides the basis for the stability of wind farm study.Second, build a small wind farm model. And research the simplified model of a small wind farm.The capacity of a single wind turbine and Multiple small-capacity wind farm simulationed to Compare the Power System Stability and effects of wind farm collector, which provides the basis for the stability of wind farm study.Finally, build a wind farm model of heterogeneous by PSCAD software, Consider the randomness of wind speed, ground fault, etc. Analysis the Grid system voltage and frequency stability base on heterogeneous wind farms. And conducted a heterogeneous wind farms into power after the cluster control technology. Analysis of the grid voltage drops, Multiple types types of wind turbine reactive power and voltage control strategy.
