摘要
将实测数据注入仿真模型中校正模型参数,可以有效提高电力系统动态仿真精度,但工作量较大。为此,提出基于电力系统分析程序包(power system analysis software package,PSASP)的发电机模型参数校正方法,将待校正发电机与系统解耦,通过实测数据计算出冲击负荷扰动量并注入到恒阻抗模型中。利用2015年8月6日吉林省白甜二线大扰动事件的实测数据,对白城发电厂1号发电机模型参数进行校正,验证了该方法是有效的。
It is able to effectively improve dynamic simulation precision for power system by injecting measured data into the simulation model for modifying parameters, but it is a great work. Therefore, this paper proposes a parameter modification method for the generator based on power system analysis software package （PSASP） which decouples the generator for mod- ification and the system, and then works out disturbance quantity of impact load based on measured data and injects into the constant impedance model. According to measured data of large disturbance of Jilin Baitian second line on August 6 in 2015, it carries out modification for parameters of No. 1 generator model, which verifies validity of this method.
