200MW以上火电机组经济性诊断系统开发及应用

Development and application of economic diagnosis system for power unit above 200MW

针对典型的200MW以上火电机组特点,研究建立了通用性经济性诊断模型,并以此为基础开发了具有较好通用性的200MW以上火电机组经济性诊断系统,其主要功能包括数据初始化、机组经济性诊断、机组最好运行水平诊断、机组热力试验和机组日常运行管理等。通过实例验证和实际应用证明,该经济性诊断与分析系统具有准确、快速、全面的特点,能有效地提高火电厂的运行管理水平,是提高机组经济性和节能降耗的有效工具。

According to the characteristics of typical power unit above 200MW, the thermo-economics diagnosing models were set up. Based on these models, a thermo-economics diagnosing system with good generalization was developed including the functions such as data initializing, thermo-economics diagnosis, optimal operation level diagnosis, thermodynamic test and daily operation management. The example and practice proved that this system was an exact, quick and general tool to improve thermo-economics and energy conservation of power unit, which could enhance the operation management level of thermal power plants.
