Abstract
For a regional power network, when under the isolated network operation condition, how to regulate the frequency to ensure the stable operation of the system has always been lack of systematic guidance. Aiming at solving the problem, based on a further study of the frequency dynamic characteristics when the isolated network was formed, a control strategy which takes islanding frequency characteristics into consideration is proposed. Firstly, according to the frequency characteristics of isolated network, a simulation model which is adapted to islanding operation is established, also the main factors which influence islanding frequency response is analyzed using simulation, then the strategy of primary and secondary frequency regulation of islanding is raised, finally, with the control strategy as a guidance, an islanding examination is conducted. The results demonstrate the control strategy to be correct and effective. The frequency control strategy presented has strong adaptability, and can be used as a control guidance of various types of thermal power unit faced with the isolated operation condition.关键词
