摘要
提出了一种对火力发电厂厂级监控信息系统(SIS)中机组负荷经济分配问题的可行解算法——RDT算法,并给出了算法框架。该算法是一种基于最小开关机时间约束的机组离散状态序列的枚举算法,可求得火电厂机组负荷经济分配的理论全局最优解。算法具有2层结构,低层求解若干凸二次规划问题,高层求解一个离散动态规划问题。求解中实现了离散变量与连续变量的解耦处理,显著降低了问题的复杂性。
An algorithm for feasible solution of units＇ load economic distribution in plant-level supervisory information system（SIS）,which is called RDT algorithm,has been put forward,and the framework of said algorithm being given.The said algorithm is an enumeration algorithm for discrete state sequence of units based on the constraint of minimum start-up and shutdown time,and it can get the theoritical global optimal solution of units＇ load economic distribution in thermal power plant.The said algorithm has a two-level structure;solving convex quadratic programming problems in the low level,and solving discrete dynamic pragramming problems in the high level.The decoupling of discrete variables and continuous variables has been realized,simplifying the complexity of problem significantly.
