To avoid dealing with the zero dynamics limitation brought by the bidirectional power flow through the back-to-back converter in a doubly fed wind generator, a new energy-based modeling and control approach for the grid- side converter is presented. During the modeling process, the grid-side converter is divided into two subsystems with the feedback interconnection structure, and the interactive matrix of the model takes into account the concrete port structure. Then, an energy-based controller is proposed to realize the grid-side control objectives based on the new model. Simulation studies are carried out in MATLAB/Simulink. Comparative results between the proportional-integral controller and the energy-based controller show that the latter one can obtain faster convergence rate and global stability as the load current varies. Moreover, the energy-based controller is also competent for grid-side control when simulated in a 2 MW wind energy conversion system with random wind.

An active crowbar protective circuit is an effective and common approach for low voltage ride through(LVrT) of a doubly-fed induction generator(DFIG). The crowbar resistance value and its switching scheme both have crucial effects on safety recovery. The effects encountered are correlative dependence and interplay so that analyzing them from a single factor, as most existing LVrT control methods would do, obtains a partial optimal solution. This paper combines these two factors toanalyze their coordination effects on the LVrT control,and to also investigate whether the global optimal performance of these factors can be achieved. The principles for resistance selection and the schemes for crowbar switching are discussed first. Next, the coupling relationship is ana-lyzed based on statistical sampling simulation data with different resistance values and various switching *** results demonstrate that their coordination has critical influence on rotor peak current, DC-link voltage and reactive power. The optimal coordination will be different according to specific requirements. Hence the global optimal combination could be achieved when all requirements are taken into consideration.

在含海上风电场的基于电压源换流器的多端直流(VSC-MTDC)输电系统中,为提高陆上电网的频率响应能力,传统附加频率控制策略会同时启动系统中的电压源换流器(VSC)来参与频率调节,这导致频繁的小扰动下,海上风电场中的风机总是偏离其最大功率点跟踪状态。为此,文中提出了一种无需通信的场网联合顺序控制方法。该方法可通过直流电压和频率阈值的判断,按照陆上电网电源到网侧VSC再到场侧VSC的顺序逐次启动系统中的调频设备,仅当扰动较大使直流电压超过阈值时,风机才参与陆上电网频率调节。与"同时"控制相比,该控制方法可显著降低频率调节对风机运行状态的影响。最后,通过一个含海上风电场的四端VSC-MTDC系统验证了所提控制方法的有效性。

对电力系统中重要节点进行有效区分,有助于在资源有限的条件下对重要节点施加额外保护或改变拓扑结构,从而提高系统鲁棒性、降低事故发生的概率。受网页排序算法启发,提出电气链接结构分析的随机方法(electrical stochastic approach for link structure analysis,E-SALSA)用于电力系统重要节点评估。该算法综合考虑了电力系统拓扑结构、潮流等因素对节点的影响,能够有效反映电力系统的真实情况,并且其特点更符合电力系统背景。在IEEE300节点电力系统中,使用失负荷规模和最大子群规模两个指标对E-SALSA算法与电气介数算法、基于共同引用的超链接引导的主题搜索(model based on co-citation hypertext induced topic search,MBCC-HITS)算法进行了对比分析。结果证明E-SALSA算法相比电气介数算法在两个指标上都具有优势,相比MBCC-HITS算法能够更综合考虑各方面因素对节点的影响,进而证明了E-SALSA算法的合理性、有效性。

目前,电力变压器的保护研究及优化多是针对传统电源,少有文献研究双馈风电场电源下计及rSC控制电路的变压器保护。而当双馈风电场并入弱电网时,传统变压器差动保护又存在动作性能变差的问题。基于此,分析了系统发生故障时,计及Crowbar保护电路与计及rSC控制电路的短路电流特性,推导了两种运行条件下短路电流经傅里叶算法提取后的误差表达式。在此基础上,分析了致使传统差动保护性能降低的原因,从而提出利用同步挤压小波变换进行故障特征提取并联合归一化二维轨迹图对故障进行识别并动作的保护新方案。该方案不受风电场短路电流特性的影响,在双馈风电场送出变中具有更好的适用性和更高的精确性。最后,在Matlab/Simulink平台上搭建双馈风电场仿真模型,验证了该方案在不同故障类型、励磁涌流、不同大小噪声及非同步数据传输影响下的有效性。
