Abstract

This paper presents a direct analytical method to predetermine the steady-state values of a permanent magnet synchronous generator (PMSG) based wind power system (WPS) at each stage of power flow. A generalized structured is developed with two independent equivalent circuits, that is, PMSG and grid side. To effectively determine the converters performance numerals despite grid disturbances, steady-state model is structured with positive sequence components of grid voltage. The advantage of the proposed model is that the methods evade the requirements of d-q modeling and a dedicated controller to evaluate the system performance. Using the proposed steady-state model, the entire WPS components ratings is predicted evading time domain simulation with complicated controller design. Also, the simple controller design is proposed to aid in optimal power flow supplement with FRT requirements under all possible system operating conditions. Ultimately, validation of predetermined values with the simulated PSCAD/EMTDC response including the proposed controller is investigated.

基于PMSG的不同工况下WPS稳态值的直接分析预测定

本文提出了一种基于永磁同步发电机(PMSG)的风力发电系统(WPS)在潮流各阶段稳态值的直接解析预估方法。提出了一种具有两个独立等效电路的广义结构，即PMSG和栅格侧。为了有效地确定电网扰动下变流器的性能数值，采用电网电压正序分量构建了稳态模型。该模型的优点是避开了d-q建模和专用控制器的要求来评估系统性能。利用所提出的稳态模型，预测了整个WPS组件的额定值，避开了复杂控制器设计的时域仿真。此外，提出了简单的控制器设计，以帮助在所有可能的系统运行条件下的最优潮流补充FRT要求。最后，通过模拟PSCAD/EMTDC响应(包括所提出的控制器)验证预定值。

期刊介绍： Having been in continuous publication since 1977, Wind Engineering is the oldest and most authoritative English language journal devoted entirely to the technology of wind energy. Under the direction of a distinguished editor and editorial board, Wind Engineering appears bimonthly with fully refereed contributions from active figures in the field, book notices, and summaries of the more interesting papers from other sources. Papers are published in Wind Engineering on: the aerodynamics of rotors and blades; machine subsystems and components; design; test programmes; power generation and transmission; measuring and recording techniques; installations and applications; and economic, environmental and legal aspects.
