燃气-蒸汽联合循环机组在线性能试验研究

Research on online performance test of gas-steam combined cycle units

机组性能试验是掌握火力发电机组、系统和热力设备等运行经济性的重要技术手段。为全面实时地对燃气-蒸汽联合循环机组进行性能监测,采用maxDNA组态语言与C语言联合编程,开发了一套在线性能试验系统,在系统中植入联合循环机组相关计算公式,通过计算模块对机组进行在线性能试验,实时监测机组的状态,为电厂节能监督工作提供技术支持,提高燃气发电机组的运行水平。

Performance test is an important technical means to master the economy level of thermal power units, systems and equipment in operation. In order to realize full monitoring the real-time performance of gas-steam combined cycle units online, a set of online performance test system was developed by maxDNA configuration language and C language, and the relevant calculation formulas of the combined cycle units were implanted into it. The real-time online performance test on units was carried out by the calculation module,and status of units was monitored. The test provides technical support for energy-saving supervision, and improves the operation level of gas-fired units.
