1、摘要全球人口增长和发展中国家的经济扩张,到2050年,世界能源需求可能翻番甚至增加两倍。地球上的全部生命都依赖于能源和碳循环。能源对经济级社会发展都至关重要,但这也带来了环境方面的挑战。我们必须探索能源生产与消费的各个方面,包括提高能效、清洁能源、全球碳循环、碳资源、废弃物和生物质,还要关注它们与气候和自然资源问题之间的关系。风力发电的发展是时代的需要。 在风力发电控制系统中,基于PLC为主控制器的设计是未来的发展方向。本设计基于PLC的风力发电控制系统,旨在保证风力发电机组的各类轴承、齿轮箱、风轮、发电机正常工作;通过选择合适的控制方法,使系统能更加稳定的运行,进而可以有效提高风力利用率。设
2、计中主要对发电机控制电路、偏航控制电路、风轮和齿轮箱及液压站的运行和工作情况进行了设计,并绘制了相应的电气原理图。在控制电路中还说明了PLC、电动机及相应低压器件的型号选择,绘制了I/O接线图;在发电机控制电路中,设计了发电机的转速控制方面;偏航电路中,设计了对风、解缆功能;在齿轮箱系统中,设计了油位控制功能。同时在设计中还详细编写了各部分的控制程序,并进行了相关调试,另外利用S7-200仿真软件进行了系统仿真验证,仿真结果满足设计要求。关键词:可编程控制器;故障监测;控制系统;传感器;风力发电窗体顶端In recent years, by the international and dome
