In this article it analyze generating unit's run by slip pressure to start with some factors. It established a optimizing mathematic model for large power station generating unit. I solve it by the way of square polyhedron. Taking a 300MW generating unit for an example, it is optimized by this way. The account result indicated that it can offer the scheme for generating unit's run by slip pressure of large power station generating unit%本文从机组滑压运行的相关因素入手,建立了大型火力发电机组滑压运行优化教学模型,采用正多面体法进行求解.以300MW机组为例,用此法进行了优化,计算结果表明,综合优化可以为制定大型火力发电机组滑压运行方案提供依据.
