The control technology for the thermal power units experienced a development from analog instrument to digitization and informatization, were developing towards the target of higher performance in automation, reliability, energy saving, and environmental protection control areas. Through the realization of the global balanced control aimed at the multi-object to the security, economy, and performance, the intelligent fine control target will be eventually realized. At present, the main factor which restricts the technology development is the lagging behind of the basic research, which limits the applied research progress. The research on the new technologies of the measurement and detection, advanced control, combustion technology of optimization, energy saving control, global sequential control, information utilization and grid-source coordinate control fields will promote the technology progress from the base to the application, realize the high speed and sustainable development of the thermal power industry automation technology.%火电机组的热工控制技术经历了从模拟仪表到数字化、信息化的发展，正向更高性能的自动、可靠、节能、环保的控制目标迈进，通过实现安全、经济、性能多目标的全局均衡控制，最终将实现智能精细化控制目标。目前制约技术发展的主要因素是基础性研究的滞后，限制了应用研究的进步，在测量检测新技术、先进控制、燃烧优化、节能控制、全局程控、信息利用以及网源协调等领域的技术研究将推动从基础到应用的技术进步，实现火电行业自动化技术的高速可持续发展。
