摘　　要：受汽轮机主辅设备性能、现场系统布置和环境温度等因素影响,复合滑压运行参数不可避免地偏离厂家所提供的设计值,机组投运后对其进行优化是十分必要的。在对传统寻优方法研究基础上,提出了基于可行压力的复合滑压运行参数寻优方法,方法以可行压力计算为基础,通过对试验工况进行遴选,最大限度减少试验工况,有效简化了复合滑压运行参数寻优过程。实例验证了方法的可行性。Subjected to the factors such as performance of main and auxiliary- equipments, local system layout and ambient temperature and so on, operational parameters inevitably deviate from design value which the manufacturer provides in composite sliding pressure operation, so it＇ s very necessary to carry on parameter optimization after unit to be put into operation. On basis of traditional methods research on parameter optimization, parameter optimization method based on possible pressure is proposed, which is based on possible pressure computation. Parameter optimization process is effectively simplified by means of prudently selecting test condition to farthest reduce test condition. The example validates feasibility of method.
