This paper addresses a detailed design of a windpower plant and turbine slope voltage control in the presence ofcommunication delays for a wide short-circuit ratio range operation.The implemented voltage control scheme is based upon thesecondary voltage control concept, which offers fast response togrid disturbances, despite the communication delays, i.e., this conceptis based on a primary voltage control, located in the wind turbine,which follows an external voltage reference sent by a centralcontroller, called secondary voltage control, which is controllingthe voltage at the point of connection with the grid. The performancehas been tested using PSCAD/EMTDC program. The plantlayout used in the simulations is based on an installed wind powerplant, composed of 23 doubly fed generator wind turbines. The resultingperformance is evaluated using a compilation of grid codevoltage control requirements. The results show that fast responseto grid disturbances can be achieved using the secondary voltagecontrol scheme, and the fulfillment of the design requirements canbe extended for a wide range of short-circuit ratios.
