| 摘 要： | 含附加频率控制的风电机组可响应电力系统的动态行为,同时也对系统的动态特性存在影响。首先基于惯性中心等效理论(center of inertia,COI),分析了大规模含附加频率控制系统双馈风电机组接入电网后,系统暂态特性的变化,并推导了惯性中心同步机转子运动方程;其次基于双馈风电机组自身运行特性,分析了其运行极限与运行模式对响应系统动态行为能力的影响;将上述分析结合得出含附加频率控制系统双馈风机对系统暂态稳定性影响的关键因素。最后在电力系统综合程序PSASP中,搭建接入双馈风机的IEEE-3机9节点电力系统模型,验证上述结论的正确性。

| Abstract: | Wind turbines with additional frequency control respond to the dynamic behavior of the grid and have some impacts on the dynamic behaviors of the system. This paper analyzes the changes of the transient characteristics of power system based on the Center of Inertia(COI) theory when large-scale doubly-fed induction generators(DFIG's) with additional frequency control system are integrated to the grid. And the rotormotion equation of the synchronous generator at COI is deduced. Secondly, based on the DFIG's operation characteristics, the capability of the DFIGs response to system dynamic behavior is analyzed. From the above analysis, the influential factors are given on the transient stability of the system integrated with DFIGs with additional frequency control. Finally, IEEE 3-gen 9-bus system model with DFIGs is built in PSASP and the theoretic conclusions are verified by simulation results. |
