Review of reactive power compensation in wind turbine



Different aspects of reactive power regulation problem in wind farms are presented in this paper. In the first part some background of the reactive power control in Wind Park is presented, including motivations for its use and methods that can be used. In general, there are active (wind generator, compensator) and passive methods (L, C) of reactive power compensation. The wind park model ( the model of doubly fed induction generator (DFIG) based wind turbines, crowbar circuit, battery storage system, transformers, cable lines between wind farm and PCC, control system) has been shown in the proposed methods. In wind farm the crowbar protection, changes from reactive power source to reactive power load with the rise of low voltage and then burden of fault power system is aggravated. In order to solve the problem a new strategy is formed where a new real time coordinate control system (RTCCS) is built. Based on reactive power compensator the STATCOM synchronizes with wind power system and the grid STATCOM exchanges the perceptual reactive and capacitive reactive which restrain system voltage fluctuation and maintain the stability of the system voltage at fault times. Wind power system and STATCOM control and reactive power control strategy are discussed with the help of basic working principle and relevant models and the simulation of actual system had been done with the help of PSCAD. The simulation result shows that STATCOM maintaining the system improves the wind power system voltage
