SPS与VB无缝集成的电力系统功角稳定仿真研究

Simulation Study of Rotor Angle Stability of Power System Based on SPS and VB Seamless Integration Method

运用MATLAB电力系统仿真模块集SPS构建了单机—无穷大系统Simulink模型,对电力系统稳定器(PSS)抑制电力系统小扰动低频振荡的效果进行了仿真;对提高电力系统大扰动功角稳定性的措施,如自动电压调节器(AVR)及电力系统稳定器(PSS)、快速切除故障、故障限流器(FCL)、自动重合闸等手段的使用效果进行了仿真验证;并结合单机—无穷大系统的Simulink模型运用ActiveX技术实现SPS与VB的无缝集成,将SPS的仿真结果用VB界面显示,较好地弥补了MATLAB用户界面不友善的缺陷,为《电力系统分析》课程进行CAI设计提供了思路。

MATLAB SPS is used to build a simulink model of single-machine infinite-bus system, and based on the simulink model, sim-ulation on effect of PSS suppressing small disturbances low frequency oscillation is carried on, and some methods of improving power sys-tem transient stability are simulated, including AVR and PSS, short circuit cleared rapidly, fault current limiter and single-phase auto re-close. The study unifies the simulink model to realize MATLAB and VB seamless integration using the ActiveX technology, and demon-strated the MATLAB simulation result with the VB contact surface. This method of MATLAB and VB integration can make up the MAT-LAB contact surface unfriendly flaw and offers a reference for the design for CAI of Power System Analysis course.
