封面故事 智能控制技术为主。” ADI Processor-DS亚洲 业务区域经理陆磊认为,风 力发电的主要挑战来自风电 系统动态控制。由于风无时 无刻不在变化,为了最大限 度的利用风能,提高风力发 电的效率,必须要对风力发 电系统进行实时的控制。 陆磊说:“对于发电系 统,大多数系统设计的任务 是执行实时控制算法,因此 大多数的控制系统采用了高 性能的处理器或DSP,其中 所用的DSP要能够满足一系 列需求。” 他表示,ADI的浮点处 理器特别适合用于应对风电 控制算法的复杂性。其中 SHARC浮点处理器作为核 心算法处 理器为业 界提供了 一种可行 的解决方 案,来满 陆磊:风力发电主要 足设计风 挑战来自风电系统动 态控制。 力发电系 统的所有关键需求。除了能 解决上述的挑战,SHARC 处理器还使开发人员可以用 一种非常灵活的方式将内部 存储器分为数据和程序存储 器,使应用程序能适应未 来需求的变化而无需改动 硬件。 此外,他还提到,对必 须在100微秒或更少时间内 执行的实时处理运算而言, 速度也是一个关键因素。另 外,风电系统的必要条件是 充足的处理器内存,以避 免造成处理延迟的等待状 态。“此外,内部存储器可 减少外部器件的数量,能最 大限度地减少电路板设计中 的EMI问题。”陆磊强调。 此外,张松刚还提到 成本和价格因素也是阻碍 风力发电增长的主要原因之 一。“风电开发最大的瓶 颈之一就是一次性投入巨 大,单位成本较火电、水电 高。”此外,长期维护也是 一个不小的负担。张松刚指 下接30页 » www.esmchina.com | 2010年8月 | 国际电子商情 29 http://www.esmchina.com/STATIC/SITE/DigitalEdition_201008.HTM#tj http://www.mitsumi.co.jp/chinese http://www.esmchina.com
