基于模糊逻辑的电力系统双反馈异步机稳定性的基础研究
发布时间：2021-08-16 22:03
Nowadays electric power systems are becoming more and more complex, and they are often subjected to various stability problems because of the unbalance between the power demand and power supply. Among the different ways being proposed to improve the dynamic performance of the system, a round rotor structure doubly-fed asynchronous machine （DASM） is investigated in the paper to control the active and reactive power of the system.On the other hand, because of the dynamic and stochastic nature of t...
