The Design And Experiment Of AVC System In Wind Farm

Countries with the strong support of the wind power generation, wind power generation in recent years the rapid development in our country, the installed capacity has improved significantly, but the power system structure of our country cause grid energy absorption ability was limited, and the wind and the size is not controllable, so the grid voltage, the wind power without put forward higher requirements regulating ability. In order to meet the requirements of real-time scheduling of grid, each sub station to improve the efficiency of staff on duty, to develop wind power automatic voltage control system.This system embarks from the actual demand of my work unit, with the experimental research, numerical analysis method for wind farm needs analysis, automatic voltage control system design and implementation, system testing. Methods through theoretical and practical automatic voltage control system is different from the traditional voltage control system, with wind power characteristics.The design of this system adopts B/S mode, using SQLSERVER2003 and C# language, through numerical analysis, logic circulation, logic judgment to realize automatic voltage control of wind farm. Through the study and research of traditional automatic voltage control system operation principle, combined with the actual characteristics of the unit has been put into operation and wind farm wind climate characteristics is located, automatic voltage control system mainly uses the numerical analysis method to develop wind power adaptation. Through the historical operation data, to accumulate through the form data system a lot of learning experience, on this basis, numerical weather prediction with the wind farm is located, the voltage level of prediction, analysis, adjustment of wind farm, in order to meet the requirement of the system.
