火电仿真技术研究

Study of the simulation technology in the thermal power plant

在电力行业中,计算机仿真一直是不可缺少的工具,它在减少损失、节约经费、提高效率、确保安全经济运行等方面发挥了巨大作用。主要介绍了计算机仿真技术在660MW火电站中的具体应用情况。以邯峰发电厂#1机为对象,采用STAR-90仿真支撑系统,建立起660MW火电机组1∶1仿真机,并在机组投产前建成,取得了良好的培训效果。论述了火电站仿真机未来的发展趋势,包括开发高精度机理性仿真数学模型以及真实的DCS仿真模型、进行性能计算与故障诊断、应用于热工人员培训及机组调试等。

Simulation is a necessary aid for development of electric power industry. It can greatly reduce losses, save costs, improve efficiency, assure the safe and economic motion. This paper mainly describes the specific application of computer simulation technology in thermal power generating units, Taking unit ^#1 of Hanfeng Power Plant as the simulation object, a 1： 1 simulation machine of 660 MW thermal power generation units is established based on the STAR- 90 simulation support system. It is put into operation before the real unit, which has gained good training results. And the prospective development trends of simulation machine of thermal power generation units are discussed in the last section, including developing highly precise simulation mathematics model based on the mechanism, calculating the properties, checking the faults, and application of which on training thermal control operator ＆ testing the units etc.
