基于TOP平台的开放式算法容器设计与开发

Design and Development of Open Algorithm Container Based on TOP Platform

发电企业采用先进控制技术是提高机组控制性能的重要手段,但常规DCS(分散控制系统)和外挂先进控制系统很少支持第三方控制算法模块嵌入,为此,设计了基于TOP(电站热工优化控制平台)平台的支持可扩展算法接口的开放式算法容器。介绍了开放式算法容器的基本原理、实现方法、算法封装接口和算法载入界面,算法容器可嵌入使用C/C++和Python语言编程实现的、符合接口标准的高级控制算法,通过载入界面将算法容器导入至TOP平台控制逻辑组态软件,与其他内置模块同样使用。以动态矩阵控制自定义算法为例,验证了高级算法容器的可行性,仿真测试表明,利用动态矩阵控制算法容器可以获得比传统PID控制更好的控制效果。

The use of advanced control technology in power generation enterprises is an important means to improve units control performance.However,the conventional DCS system and external advanced control system rarely support the embedding of the third-party control algorithm module.Therefore,an open algorithm container based on the TOP platform supporting a scalable algorithm interface is designed.The basic principle,implementation method,algorithm encapsulation interface and algorithm loading interface of the open algorithm container are introduced.The algorithm container can be embedded with the advanced control algorithm which is programmed in C/C++and Python language and meets the interface standard.The algorithm container is imported into the TOP platform control logic configuration software through the loading interface and can be used in the same way with other built-in modules of the TOP platform.As an example,the feasibility of the advanced algorithm container is verified.The simulation test shows that the control effect of the dynamic matrix control algorithm container is better than that of the traditional PID control.
