南方电网交直流混合输电系统动态潮流仿真计算

针对调度员培训系统的仿真要求,根据直流系统分层的特点建立了系统和极两层对象,在直流系统这一层次上建立了其接线方式的描述,用以控制直流系统电气方程的建立.可以实现对直流系统不同运行接线方式的模拟以及分层控制的模拟,基于动态潮流的原理对直流系统进行建模,考虑了高压直流的频率特性,实现了基于动态潮流技术的交直流联合系统的仿真,为调度人员提供了逼真的交直流联合输电系统的培训环境.

Study on Dynamic Power Flow Simulation for AC/DC Hybrid Transmission System of China Southern Power Grid

In accordance with the demand to dispatcher training simulator (DTS), a model with system layer and pole layer is constituted for HVDC power system based on its layered character. A modeling method to describe the line connection modes on the system layer is supposed, which can be used to establish electrical equations of HVDC system. So the simulation to 'different operation modes, as well as the layered controls, can be realized. This modeling method considered both the principle of dynamic power flow and frequency character of HVDC. It can be used to achieve united simulation of AC/DC system based on the dynamic power flow technology and a living training environment is provided for dispatchers.
