摘　　要：新能源场站(如风电场和光伏电站),作为可再生能源发展的主要形式,其接入电网不仅提高了能源利用效率,还促进了绿色低碳经济的发展。然而,新能源场站发电的随机性、波动性和分布性使得并网点的电压控制变得更加复杂。电压控制的核心目标是通过合理的设备配置和运行策略,保持电压稳定,提升电网的安全性与经济性。从新能源场站电压控制的基本原理出发,详细探讨了无功补偿、逆变器控制、变压器调压和电压/无功自动控制系统等关键技术,并分析了集中式与分布式电压控制策略的适用场景及优势。结合现代电力系统发展需求,进一步提出了新能源场站电压控制现存问题及发展方向,能够有效提升电网的稳定性与调节准确度,推动智能电网的发展。As the main form of renewable energy development,the integration of new energy stations,such as wind farms and photovoltaic power stations,not only improves energy efficiency,but also promotes the development of a green and low-carbon economy.However,the randomness,fluctuation and distribution of power generation at new energy stations make the voltage control of grid-connected points more complex.The core goal of voltage control is to maintain voltage stability and improve the safety and economy of the power grid through reasonable equipment configuration and operation strategies.Based on the basic principle of voltage control of new energy stations,this paper discusses in detail the key technologies such as reactive power compensation,inverter control,transformer voltage regulation and voltage/reactive power automatic control system,and analyzes the application scenarios and advantages of centralized and distributed voltage control strategies.Combined with the development needs of modern power system,this paper further puts forward the existing problems and development directions of voltage control of new energy stations,which can effectively improve the stability and regulation accuracy of power grids and promote the development of smart grids.
