摘要
随着大规模的新能源场站建设投产,其有功功率随机波动给电力系统带来了全方面的严峻考验,高渗透率的新能源并网将引起系统频率偏差变大,电力系统的频率控制能力建设显得愈发重要。研究了风电场的有功功率控制策略,分析了风电场参与一次调频的基本原理,并基于相关标准要求,对风电场站的关键技术进行研究并进行优化。现场试验结果表明,通过优化后的控制逻辑及技术具有实际有效性,能够提升场站的一次调频支撑能力。
With the construction and production of large-scale new energy stations,the random fluctuation of active power has brought severe tests to the power system in all aspects.The grid-connected new energy with high permeability will cause greater frequency deviation of the system,and the construction of frequency control capacity of the power system becomes more and more important.In this paper,the active power control strategy of the wind power plant is studied,the basic principle of the wind power plant participating in primary frequency regulation is analyzed,and the key technologies of the wind power plant are studied and optimized based on the relevant standard requirements.Field test results show that the optimized control logic and technology have practical effectiveness and can improve the primary frequency regulation support ability of the station.
