摘　　要：分布式新能源因具有清洁、可再生性、成本低以及发电便捷等优势,逐渐成为电力行业的主流发电方式。与传统发电方式相比,用户对新能源电力系统运行的安全性与稳定性提出了更高要求。在电力系统维护过程中,自动电压无功控制对提高电力系统的输送电压质量以及降低电网损耗,促进电力系统调节的自动化信息水平的提高具有重要意义。基于此,为了改进分布式电力系统的无功电压的调节方式,提出了一种新型的无功电压自动调节技术。该技术的核心是对功率因数的优先控制,通过构建无功电压自动控制系统,对新能源电力系统电压、无功进行实时监视,从而进一步控制电力系统的输送电压,这在一定程度上等效实现了电力系统自动调节的功能。经实验验证,所构建的自动电压无功控制功率因数优先补偿技术在新能源电力系统维护中的应用优势明显。Distributed new energy sources have gradually become the mainstream power generation methods in the power industry due to their advantages of cleanliness,renewability,low cost,and convenient power generation.Therefore,compared with traditional power generation methods,users have put forward higher requirements for the safety and stability of the operation of new energy power systems.Automatic voltage and reactive power control is of great significance in improving the quality of transmission voltage and reducing grid losses,and promoting the improvement of automation information level in power system regulation.Based on this,in order to improve the regulation of reactive power and voltage in distributed power systems,this paper proposes a new type of automatic reactive power and voltage regulation technology.The core of this technology is the priority control of power factor.By constructing a reactive power and voltage automatic control system,the voltage and reactive power of the new energy source power system can be monitored in real time,thereby further controlling the transmission voltage of the power system.To a certain extent,it effectively realizes the function of automatic regulation of the power system.And it has been experimentally proven that the automatic voltage reactive power control power factor priority compensation technology constructed in this paper has significant advantages in the maintenance of new energy power systems.
