摘要
燃气轮机控制系统普遍采用数字电子控制技术,国内自行研制的数字电子控制器多为集中式控制器,控制软件复用率低、研发周期长,可靠性的提高受到了制约。而国外正在朝着模块化、通用方向发展。提高我国燃机控制系统的设计水平,研制具有自主知识产权的燃机数控系统变得越来越迫切。
本文首先介绍了通用燃气轮机控制系统的组成及工作原理,阐述了控制系统的发展历程及各阶段采用的主要技术,论述了采用实时以太网进行控制软件设计的必要性。在对几种工业控制网络分析比较的基础上,确定了基于EtherCAT实时以太网的电子控制器方案,然后开展了基于EtherCAT的控制系统的设计。在控制系统的实现中,设计了以PowerPC处理器MPC5200B为核心的主站和以DSP处理器TMS320F2812为核心的从站,并完成了主站控制软件、主站通讯软件和从站通讯软件的开发。最后进行了主站软件和从站软件的EtherCAT实时通讯调试,验证了设计方案的可行性。研究表明,以EtherCAT实时以太网构建的燃机控制系统具有实时性好、软件维护方便、可靠性高等优点,是燃机控制系统软件设计的发展方向。
Digital electronic control technology has been mostly applied to gas turbine control system. Most domestic independently developed digital electronic controllers are the central controller, the control software reuse rate is low, research and development cycle is long, the reliability improvement has been constrained. But there is a trend of developing the control systems with general modules in western countries. Improving China's gas turbine control system design level, and developing independent intellectual property rights of gas turbine control system have become increasingly urgent.
The constitute and working principle of common gas turbine control system are firstly introduced, and then the development and the main technology adapted in each stage are expounded, the necessity of control software design based on the real-time ethernet is discussed. It is determined to develop electronic controller based on EtherCAT on the basis of comparative analysis to several industrial control networks, and then carries out the design of its control system. In the process of implementing control system, the paper designs an EtherCAT master station based on the PowerPC processor of MPC5200B, and several EtherCAT slave stations based on the DSP processor of TMS320F2812. The EtherCAT master station software and the slave stations software are developed. At last, the real-time performance of EtherCAT bus are tested between the EtherCAT master station and the EtherCAT slave stations, the feasibility of the design is verified. The research shows that gas turbine control system has the advantages of good software real-time, easy software maintenance and high reliability and so on. It is the development direction of gas turbine control system design.
