摘要

本文详细介绍了如何有效、准确地确定风力发电互联电网的时域谐波状态估计(TDHSE)。TDHSE 方法可获得电网状态变量和系统输入。该算法使用的测量设备数量有限,可能会受到噪声和/或严重误差的污染。风力发电源模型代表了风能转换系统的动态运行。它基于一台 4 型风力涡轮机和一台直驱永磁同步发电机,以及一个全比例背靠背功率转换器。风力发电源假定风力波动和角速度控制驱动器的变化,以估计其动态行为和对电网的影响。案例研究考虑了三相电网的分析,即谐波注入、风力发电源和风力发电场。通过与 PSCAD/EMTDC® 解决方案直接比较,验证了所分析案例研究的 TDHSE 结果,TDHSE 与模拟器响应之间的一致性非常接近。

Time-domain harmonic state estimation of three-phase power networks including wind generation sources

Time-domain harmonic state estimation of three-phase power networks including wind generation sources

This contribution details the effective and accurate determination of the time-domain harmonic state estimation (TDHSE) of power networks interconnecting wind generation sources. The TDHSE method obtains the state variables of power networks and the system inputs. The algorithm uses a limited number of measuring devices, which can be contaminated with noise and/or gross errors. The wind generation source model represents the dynamic operation of a wind energy conversion system. It is based on a type-4 wind turbine and a direct-drive permanent magnet synchronous generator with a full scale back-to-back power converter. The wind generation source assumes wind fluctuations and changes in the angular speed control drive to estimate its dynamic behaviour and the effect on the power network. Case studies are considered for the analysis of a three-phase power network, i.e. with harmonic injections, with a wind generation source and with a wind farm. The TDHSE results of the analysed case studies are validated through direct comparison against the PSCAD/EMTDC® solution, obtaining a close agreement between the TDHSE and simulator responses.
