Abstract
This letter proposes an optimized frequency-locked loop (FLL) for the permanent magnet synchronous generator-based wind turbines to achieve fast inertial response. First, the principle of inertial response is analyzed, finding that changing the FLL output phase can realize inertial response. Then, the optimized FLL is proposed by integrating the estimated angular frequency error and its derivative into the output phase, which enables an instantaneous inertial response. Compared with the classical
df/dt
inertia control, the proposed optimized FLL reacts to frequency changes faster, and better rate of change of frequency and frequency nadir are obtained. Finally, the proposed method is validated by experiments.
期刊介绍：
The IEEE Transactions on Power Electronics journal covers all issues of widespread or generic interest to engineers who work in the field of power electronics. The Journal editors will enforce standards and a review policy equivalent to the IEEE Transactions, and only papers of high technical quality will be accepted. Papers which treat new and novel device, circuit or system issues which are of generic interest to power electronics engineers are published. Papers which are not within the scope of this Journal will be forwarded to the appropriate IEEE Journal or Transactions editors. Examples of papers which would be more appropriately published in other Journals or Transactions include: 1) Papers describing semiconductor or electron device physics. These papers would be more appropriate for the IEEE Transactions on Electron Devices. 2) Papers describing applications in specific areas: e.g., industry, instrumentation, utility power systems, aerospace, industrial electronics, etc. These papers would be more appropriate for the Transactions of the Society which is concerned with these applications. 3) Papers describing magnetic materials and magnetic device physics. These papers would be more appropriate for the IEEE Transactions on Magnetics. 4) Papers on machine theory. These papers would be more appropriate for the IEEE Transactions on Power Systems. While original papers of significant technical content will comprise the major portion of the Journal, tutorial papers and papers of historical value are also reviewed for publication.
