摘要:
为了提高变流器电网适应性、解决电网三相瞬态断开又重合闸时并网双馈风力发电机组的孤岛穿越难题,文章详细分析了孤岛运行机理并建立相应数学模型,探讨了机组孤岛运行模式下的电网频率、电压特性并进行了电网稳定性分析,在此基础上提出了一种基于虚拟同步控制的并网双馈风电机组孤岛穿越技术方案。通过搭建2.0 MW 双馈风电机组的变流器- 发电机Matlab 模型,仿真实现了电网断电又重合闸时并网型双馈风电机组孤岛穿越全过程运行,结果验证了该方案的有效性和可行性。该方法不仅适用于单台机组孤岛穿越工况,还可用于整个风电场或相邻风场的孤岛穿越工况。
Abstract:
In order to improve the converter adaptability of grid, and address the island-through technical problem of grid-connected doubly-fed wind turbine when the three-phase instantaneous break and auto-reclosing faults happened to the grid, it presented an islandthrough technical solution based on virtual synchronization. Firstly, the operation mechanism of isolated island was analyzed and its mathematical model was established, meanwhile the characteristics of frequency and voltage of power grid and stability of the doublyfed wind turbine in the isolated island operation mode were discussed. As a consequence, Matlab simulation model of converter-generator for 2.0 MW double-fed wind turbine was built, in which all kinds of operations for the double-fed wind turbine were fulfilled. Finally, the effectiveness and feasibility of the scheme was verified by virtue of a 2.0 MW back-back test bench. The method can be applied to not only single wind power unit, but also whole wind power plant.
