摘　　要：为了有效地提高我国中小热电厂的热力系统控制技术水平，采用模块化的编程和分析方法以适应热动力系统的结构多样化，运用分级多层次冗余容错结构提高系统的可靠性，并综合应用新型的控制理论和策略以解决常规控制难以解决的控制难题。介绍了软件包的构成以及采集、控制、执行模块的划分和建立方法。该软件包具有适用面宽，可靠性高，使用方便等特点，为热力系统的自动化改造提供了一个灵活的集成工具。经不同组态已成功应用于多个小型热力系统中，初步显示了其优越性。In China, in order to effectively enhance the automation degree of the thermal control systems of the medium and small power station in China, and to adapt the different constructions of these thermal systems, the strategy of using modular analysis and programming method is taken. To improve the reliability of the systems, hierarchical multi tiered redundancy error tolerance structure is presented. Some new control theories and tactics are applied to solve the control problems on which normal control methods can hardly obtain successful control effects. The software package presented has the features of general purpose, high security, easy to use, etc., and provide a feasible integration tool for thermal system automation reengineering. The details of software configuration, data acquisition control strategy, modular setup and implementation are listed. It has been successfully applied in several thermal systems.
