摘要
随着现代工业生产发展,电能需求日益增强,电力工业进入了大电网、大机组和高度自动化时代。单机组容量进一步扩大、我国国民经济稳步快速发展造成的用电结构发生了巨大变化,电网峰谷差别进一步拉大。因此对大型单元机组的自动控制系统提出了更高的要求。对于主要发电设备汽轮机来说,其控制系统数字电液控制系统(DEH)也提出了更高的要求。
本课题以汽轮机数字电液控制系统为研究对象,对其控制原理、组成以及控制策略和在浙江浙能舟山超超临界1000MW机组上的实现方式的研究。主要工作如下:
1.研究了汽轮机控制的原理与调解特性。介绍现阶段数字电液控制系统的原理与调节特性参数。
2.结合数字电液控制系统的原理和调解特性,提出汽轮机数字电液控制系统的设计方案组成。
3.根据控制原理提出本课题的控制策略。结合待建的浙江浙能舟山六横电厂1000MW超超临界机组的实际情况,提出浙江浙能舟山六横电厂舟山配置的配置方案。
Following with the modern industry production development, energy demand increases increasingly, power industry to enter the more power grid, big unit and highly automation era. Thermal power unit also gradually from the previous small capacity units ( mainly 300MW following volume ) for the development of large capacity, high parameter unit(Even more than 1000MW unit 600MW).In 2004, the first domestic 600000 MW Supercritical Unit--Henan Qinbei Power Plant Unit 1 operation. In 2006, the first domestic ultra supercritical 1000MW unit in Zhejiang Yuhuan plant. As of December 31, 2010, China has been put into operation in 1000MW ultra supercritical unit reached 32 units, and is on the rise. At the same time, large capacity 1250MW, 1300MW units also began to enter into people's vision.
Along with the single unit capacity to expand further and our country national economy steady and rapid development caused by electricity structure also produced tremendous change, peak valley difference is pulled further big. So for large unit automatic control system has put forward higher requirements. The main power equipment of steam turbine, the control system of digital electro-hydraulic control system ( DEH ) also put forward higher requirements. This topic in the steam turbine digital electro-hydraulic control system as the research object, the control principle, composition and control strategies in Zhejiang and Zhou Shan for the supercritical 1000MW unit implementation way research. The main research contents are as follows:
1. The first issue of the combination of domestic and foreign situation as well as the history of the research background of this topic is expounded.
2. This paper studies the characteristics of steam turbine control principle and mediation. At present digital electro hydraulic control system principle and adjusting parameters.
3. Combined with the subject of digital electro hydraulic control system principle and basic characteristics of the proposed mediation of steam turbine digital electro- hydraulic control system design.
4. The research combined with the control principle of control strategy of this paper
5. Combined with the building of Zhejiang Zhou Shan power plant for six transverse 1000MW ultra supercritical unit of the actual situation, put forward Zhejiang power plant in Zhou Shan for Zhou Shan and six horizontal configuration scheme.
6. Presenting the summary and prospect.
