摘要

本文讨论了一种与机械装置相关的风力涡轮机框架的pid彻底控制,其中计算已经产生,允许使用与矩阵侧相关的四腿逆变器的控制结构,以注入可访问的活力,就像填充一个功能的力通道一样,减轻负载电流恶化并改善力质量。考虑具有三级和单级直载荷和非线性载荷的四线框架。在风力涡轮机的关联中,公用事业侧控制器的目的是补偿在接受性、非直接和不平衡的单级和级内负载附近引起的不安影响,尽管它提供了所需的动态和响应功率。在没有风控的情况下,提出了利用直流连接电容器和连接到晶格的功率转换器来提高电能质量的控制器。本文中所提出的技术与其他技术的根本区别在于,所提出的控制结构依赖于保守权力理论的退化。这一决定为逆变器控制提供了解耦的功率和电流参考,提供了真正的适应性,特殊和突破性的功能。一直进行编程基准测试,以评估所建议的控制计算在完全连续使用下的执行情况。利用Opal-RT和TI DSP在其上的设备(HIL)上实现并验证了控制技术。在MATLAB/SIMULINK中对控制系统进行了实现和验证。结果证实了我们的能力质量改进控制,并允许禁止分离通道,增加了一个逐步最小化的、适应性强的、可靠的电子执行,这是一个敏锐的框架控制。

Pid Controller Based Grid Connected Wind Turbine Energy System for Power Quality Improvement
A thorough control of a breeze turbine framework associated with a mechanical plant with pid is talked about in this undertaking, where a calculation has been produced permitting a control structure that uses a four-leg inverter associated with the matrix side, to infuse the accessible vitality, just as to fill in as a functioning force channel, alleviating load current aggravations and improving force quality. A four-wire framework is considered with three stage and single-stage straight and nonlinear burdens. Amid the association of the breeze turbine, the utility side controller is intended to repay the unsettling influences caused in nearness of receptive, non-direct as well as lopsided single-and intra-stage loads, notwithstanding giving dynamic and responsive power as required. At the point when there is no wind control accessible, the controller is proposed to enhance the power quality utilizing the DC-connect capacitor with the power converter joined to the lattice. The fundamental contrast of the proposed technique as for others in the writing is that the proposed control structure depends on the Conservative Power Theory deteriorations. This decision gives decoupled power and current references for the inverter control, offering truly adaptable, particular and ground-breaking functionalities. Constant programming benchmarking has been directed so as to assess the execution of the proposed control calculation for full continuous usage. The control technique is actualized and approved in equipment on top of it (HIL) in view of Opal-RT and a TI DSP. The control system is actualized and approved in MATLAB/SIMULINK. The outcomes confirmed our capacity quality improvement control, and permitted to prohibit detached channels, adding to a progressively minimized, adaptable and solid electronic execution of a keen framework based control.
