摘要
分析在特高压交直流系统中由于混合系统间的互相影响从而会产生的主要问题;运用基于MATLAB的电力系统分析工具箱PSAT仿真软件,建立简单的3机9节点的特高压交直流系统模型,对其遭受大扰动情况时进行时域仿真,分析系统在大扰动下出现的电压稳定以及功角稳定问题;对交直流混合系统与纯交流系统的时域仿真分析与比较,分析混合系统稳定性的不同之处.
This paper attempts to analyze the main problems arising from the interaction of mixed power systems in UHV AC and DC power system. A model for a three-machine nine-bus UHV AC and DC system is built by using PSAT, simulating software, which is a power system of analyzing toolbox based on MATLAB. The model is simulated in time domain when it is setting large disturbances. The voltage stability and load angle stability are studied according to the simulation. Then, DC-AC-mixed system and pure AC system are stimulated in time domain and compared, so as to explore the difference of stability of mixed system.
