摘要
等值风电机组功率暂态响应参数优化,能够有效提高电力系统暂态过程的稳定性能。传统仿真软件缺少准确的风力发电系统暂态参数及其控制模型,在一定程度上影响了分析大规模风电接入后电网暂态过程响应特性的准确度。文章提出一种计及特定风速条件下风电机组有功和无功输出限制的风电系统功率暂态控制模型。该模型由风电系统有功出力控制、无功出力控制及功率极限优化控制3部分组成。利用ADPSS仿真平台搭建了针对风电系统暂态过程的控制模型,并对风电与火电并网系统进行仿真分析。仿真结果表明,该控制模型能够有效地提高大规模风电接入条件下的电力系统暂态响应特性。
The optimization of the power transient response parameters of the equivalent wind turbine can effectively improve the stability of the power system transient process. The traditional simulation software lacks accurate transient parameters and control model of wind power generation system, which affects the accuracy of response characteristics of power grid transient process after large-scale wind power access. This paper proposes a power transient control model for wind power systems that takes into account the active and reactive output limits of wind turbines under specific wind speed conditions. The model consists of three parts:wind power system active output control,reactive power output control and power limit optimization control. The transient process control model of wind power system is constructed by ADPSS simulation platform,and the wind power and thermal power grid-connected system are simulated. The simulation results show that the control model can effectively improve the transient response characteristics of power system under large-scale wind power access conditions.
