Technical Transformation of Grid Friendly Power Control System for Doubly-fed Induction Wind Farm
In response to the high penetration rate of new energy installed capacity in China's power grid,there is an urgent need for photovoltaic power stations and wind farms deeply participating in grid peak shaving and voltage regulation.This paper analyzes the current situations of the power control system of doubly-fed wind farms,which has a complex structure,overlapping functions,multiple information transmission links,high failure rate,and outdated control strategies.It also demonstrates the necessity and possibility of technological transformation of grid friendly power control systems in doubly-fed wind farms,and proposes various improvement measures,including optimizing the system structure,improving control strategies,simplifying communication networks,and fully leveraging the excellent active/reactive power control capabilities of doubly-fed wind turbines.An example of the technical transformation of the doubly-fed wind farm power control system is given as an explanation.At the same time,the paper discusses whether it is necessary to install reactive power compensation devices in new energy power stations.The acceptance test shows that the technical indexes of the modified wind farm power control system are superior to the national technical standards.The successful application of this technology is conducive to the safe,stable and economic operation of the power grid.The promotion of new wind power plants can reduce expensive one-time investment,reduce operating losses,and have great social benefits and considerable economic benefits.
