相关技术与谱分析技术是近几年发展起来的一门新的边缘科学,它是建立在概率论和随机过程理论基础上的。目前这种技术已广泛地应用到控制、力学、地震学及医学等领域。以前测定调节系统或元件的动态特性是采用飞升特性或频率特性法。这种方法不仅时间长,而且要求离线进行,对于发电设备,离线试验的机会很少,成本高。用相关技术与频谱分析技术来识别系统或元件的动态特性,可以实行在线识别,因此对动力设备的动态特性研究具有很大意义,本文介绍了如何在哈汽厂电液转换器试验台上,应用数据处理计算机识别动态特性的,希望为电厂动力设备的在线识别积累经验。
Related technology and spectrum analysis technology is a new edge science developed in recent years. It is based on the theory of probability and stochastic process. At present, this technology has been widely applied to the fields of control, mechanics, seismology and medicine. In the past, the dynamic characteristics of the control system or components were measured by soaring characteristics or frequency characteristics. This method is not only a long time, but also requires off-line, for power generation equipment, off-line test of few opportunities, high cost. Therefore, it is of great significance to study the dynamic characteristics of power equipment by using the relevant technology and spectrum analysis technology to identify the dynamic characteristics of the system or components. This article describes how to test the dynamic characteristics of the system or components, Application of data processing computer to identify dynamic characteristics, hoping to gain experience in on-line identification of plant power equipment.
