风气互补发电系统与电力系统相互影响的研究

为研究风气互补发电系统对电网的影响,首先搭建了由风电机组、燃气轮机、电网线路、静止无功补偿器、电力系统稳定器和大型水力发电机组成的仿真系统,并对该系统的负载侧和电网线路中部节点进行了稳定性分析。仿真结果表明,电网在加载了风气互补系统后运行能保持稳定,并能在发生短时故障后恢复到原来状态。该文为进一步研究风气互补系统与电网的相互影响提供了良好的模型基础。

STUDY ON INTERACTION IMPACT BETWEEN WIND/GAS TURBINE HYBRID POWER SYSTEM AND POWER GRID

The wind/gas turbine hybrid power system can repair the randomicity and uncontrollability of wind power generator system. In order to study the influence of wind/gas turbine hybrid on power grid, a simulation model combined wind/gas turbine generator system with electrical network, SVC, PSS and large hydro power plant was built in the paper. The transient stability for the nodes of the load and middle of the line were studied. The simulation results that the power grid can maintain stability after the windlgas turbine hubrid power system is connected with the network, and the power grid can restore stable after transitory malfanction happening. The simulation results provide a theoretical model for the further detail research.
