摘要
利用PSASP的用户程序接口(UPI)功能,在Windows环境下,采用动态链接库交换文件数据信息,实现将一种牵引负荷模型接入电网进行暂态稳定仿真计算。对比牵引负荷模型与传统负荷模型对系统暂态稳定计算的影响,结果表明:牵引负荷模型对电压扰动的敏感度大于恒阻抗模型而小于感应电动机模型;牵引负荷模型的功角阻尼特性优于恒阻抗模型而次于感应电动机模型,且随着牵引负荷比例的提高,阻尼比增大,故障极限清除时间减小;与感应电动机模型相比,采用牵引负荷模型时的暂态稳定性更高。
The UPI（User Program Interface） function of PSASP is adopted to embed the traction load model into power grid for the calculation of transient stability simulation in Windows environment by exchanging the file and data information with the dynamic link library. Its impact on system transient stability is compared between traction load model and conventional load model,and results show that,the sensitivity of traction load model to voltage disturbance is bigger than that of constant impedance model while smaller than that of inductive motor model;the power-angle and damping characteristic of traction load model is superior to that of constant impedance model while inferior to that of inductive motor model;along with the increase of traction load penetration,the damping rate raises while the critical clearance time decreases;the transient stability calculated with traction load model is higher than that calculated with inductive motor model.
